Title: Julian's Scrambler build "Post 1"
Post by: JulianM on 20.08. 2012 10:57
Hi, thought I would now start the build I mentioned before. Been compiling a few pics etc and hope I can keep it interesting for you all.

Firstly a little project background.
I bought a nice "looking" BSA Super Rocket that had been visually very nicely converted to a Spitfire Scrambler, and it had been built with all the right bits etc and photo documented. Should have been one to just take home and enjoy!  Guy was short of money so got it cheap enough without ripping him off. (I should be so lucky)

Here it is,
(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_IMG_4023.jpg&hash=53d2ec79df451aeb87cd13e92bd3032b03969f27) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=IMG_4023.jpg)

First thing to do was to fit some proper tyres fitting for such a machine.
(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_IMG_4320.jpg&hash=c1517653463f978824f68e3c7240548b35904049) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=IMG_4320.jpg)

And so I had a play with it in my yard, (which is quite big)
The performance was VERY disappointing and I kicked myself for only hearing it and not test riding it but as I collected it at 10pm it was not the easiest thing to test with no lights etc.
So I fiddled with it and eventually found the float level on the TT carb massively low. This was adjusted and performance improved tenfold!
However!!!!!!
After about 5 runs up the yard and back there was a loud nock under load, just like big end bearings! Subsiding when retarded.  *sad2*  *sad2*   So, put it away and decided to do a full rebuild on the complete bike.  I didn't love it any more  :!

Problem with me is that when I pull something apart I start to imagine and fantasize and get quite imaginative!  That's my job after all.
But sometimes I get a little carried away.  That's what happened here!
I had a set of old Marzocchi 38mm forks from an old 60s scrambler in my collection of bits in the "parts room" and thought I maybe should fit them, on offering them up they were 70mm longer than standard and would lift the front just nicely I thought. So one evening I fitted them in a mockup.
I also had some nice period looking "Redwing" racing rear shocks which happened to be about 1" over stock, so fitted these too.  Bike looked really good but the tank was steel and oil tank heavy etc etc.
I then managed to find a twin carb head on ebay while no one else was looking and got it pretty cheap in really excellent condition. Tested it as standard on my flow bench against my big valve single carb head and got some pretty impressive results for an un touched head that everyone says "won't flow"  ;)  
Mocked that up and mounted a pair of new 32mm Amal Concentrics from a Commando with a quick pair of manifolds I made.

Then it was off to my friend "Frank the Tank"  http://streugmetalshop.be/  for some finer modifications.

Here she is with Frank,
(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_bsajulian036.jpg&hash=89e73ab250600b3fa648e2de889c1b36c3bc5c8a) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=bsajulian036.jpg)
The new tank is ally and about 1 1/2" longer than std at the front end, and narrower at the sadle end. Subtle but very pleasing.
(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_IMG_5370.jpg&hash=18d02dcf257d96a8255ad2928d94f7b54777bf09) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=IMG_5370.jpg)

When it came back, I made some extensions to raise the rear an inch and a half more in order to get the look I wanted and then made the front and rear mudguards myself.  The rear mudguard is completely sealing off the rear "inner frame area" so as not to get mud in my air filters etc.

(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_IMG_9977zoom.jpg&hash=34b9148a9a3c8ffee90a7ea1d71b2aa259437cca) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=IMG_9977zoom.jpg)

Initially I was going to run with no front guard but in some classes you have to have one so I made this one to look period and I think it works quite well.

(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_IMG_0048.jpg&hash=91ffd5f3c42cfadf4c2b3894bd8928515b44d0dd) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=IMG_0048.jpg)

I also made a pair of long bent trumpets to go from the carbs to the air filter area under the saddle, this is bent ally tube with a nice big bell mouth formed on the end. Foam air filters will then fit offer the trumpets.  You can also just see the new oil tank I made to fit under the seat.

(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_IMG_9993zoom.jpg&hash=3a1a59f2623022c41580c6db1d76c71332ccf162) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=IMG_9993zoom.jpg)

Also cut and modified the front "roundel" to fit and mount directly round the new headlight and made the stainless headlight holder and mesh cover for the lens

(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_IMG_9857.jpg&hash=2f79530788e32c34b65814fce09fb525b0bbc4be) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=IMG_9857.jpg)

And then finished the inlet manifolds properly,

(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_IMG_0911-1.jpg&hash=3fe057319e98cf2445e13877685d67436323f28a) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=IMG_0911-1.jpg)
So this is how it ended up looking with me quite happy with the general look.

(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_IMG_0048.jpg&hash=91ffd5f3c42cfadf4c2b3894bd8928515b44d0dd) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=IMG_0048.jpg)

Stripdown time!
And time to do some mods to the frame.


(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_IMG_0152.jpg&hash=c992c7e97b83cae120f2f9d73e0223e0854897aa) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=IMG_0152.jpg)

Basically these consist of the following.
Rear mudguard loop.
Reinforcing swingarm mounting,
Front down tube bracing,
Modified head stock, extended and modified to fit the Marzocchi fork yolks and taper rollers.
Side stand and side stand bracket made to tuck the long stand up and out of the way when not in use.
Head stock bracing,
Steering stop tubes.
Numerous small tacking and bracing jobs.

Then off for frame painting.
I was going to do the frame and some of the tank etc Black, but could not sell it to myself in the end so chose a nice dark grey metallic.
Hope you like it when finished.

On return it was time for assembly to start.

Re-bushed the swingarm with newly made bronze bushes, and modified to take grease nipples, new spindle bought and fitted but drilled with a 3mm hole in the centre so the grease can get to the brake spindle also. Notice the much thicker frame support for the swing arm spindle.

(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2FBSA%2520Build%2Fth_IMG_0807.jpg&hash=3017c851abd6b4a3cff90021db9d752f06fba992) (http://s3.photobucket.com/albums/y96/lagonda/BSA%20Build/?action=view&current=IMG_0807.jpg)

Next job was to tidy and polish the yolks,
These were just tidied with the die grinder and a little weld here and there to plug unsightly holes etc. and then finished off with the rasp file and then a needle file where needed.

Followed by polishing on the mop and fitting up to the frame.

Dear Mr Admin,
On my "Hi" post I did ask where to post the build thread and this was the answer.

"Start a new topic in the engine board call it monster mash or something to suit.
Cheers"
 
However I don't mind where it is as long as people like to read it and enjoy.

a beautiful non standard bike, not easy to do, you need a mind that can see the finished article from way off.

congratulations JulianM , hope you enter the next photo competition

Might have to send the cafe over for a refurb. Any chance of knocking up another set of those inlet manifolds?

On my "Hi" post I did ask where to post the build thread
No problem, and I think will be widely read with great interest, don't worry. btw usually we are trying to avoid big pictures in posts (only thumbnails, to avoid 3 meters deep posts... or 2 meters wide if anyone links to some massive picture) but this post was nicely made with great content, and I suppose links to screen-size pictures should be allowed in the bikes & pictures board. Please do not edit or change picture hosting settings, or else all pictures will disappear from here, to avoid this it's good to use the forum attachments service (but ftm one cannot put pictures inside the post, they all end up at the end of the post). End of offtopic :O)

Thanks for the kind words everyone, it helps to inspire very much!

Will do the photo comp if it's finished in time and if I can take a good photograph!  Two big "ifs"   *smile*

Muskrat,
Yes, I can do some manifolds but need a bit of time first.  (very short on that at the moment)
Drop me a line and we should get together and natter about what you need sometime.
I only do things for free or for "swapsies" though as I try to stop it crossing over with work and stopping it being so much fun  ;o)

Regards,
Julian

PS.
A10gf,  Will try to make sure it's as forum friendly as poss.  Thanks for the pointers.

Hi Julian,
I was away last week and somehow missed your postings
The way the build is going there wont be much BSA left and mostly replaced by "Julian parts"  LOL *smile*
Looking forward to the engine build pictures, and those alloy barrels *ex* *ex*

Post by: JulianM on 03.09. 2012 13:39
*smile* *smile*
I know what you mean and partly true.
My "ethos" behind it all was to build a BSA based scrambler using all parts from the A10 Super Rocket (what my bike started it's life as) and ending up with what someone could have built in the late 50's early 60's  hense the 190mm front brake and steel wheels etc that ideally should be replaced to save weight etc, for a tidily japanese one from a 70's MX bike or a twin leader from something more trick.  Even the forks are Marzocchis from an ex-works 63 Husky apparently, (leftovers from a mate of mine that was lucky enough to have once owned one)  so it should be as much BSA as any real competition bike would have been in period "if you understand my meaning"  which is why I am going to the effort to make the engine fast and reliable instead of sticking in a Triumph motor.

A bit of a test to see what could be done to an open class BSA A10 with what was available at the time.

Regards,
julian

PS.
The new crank is almost finished   *smile*
Did I not mention the new crank? 
Well I "need" it to get as big and bad as poss.  so now it will be 780cc which is ok by me!

Small update,
Had a little chat with the CNC man last week as I was sorting out to start machining and we decided to get the bores ceramic coated and run the pistons direct with no liners, similar to Nikasil bores etc. This means with a little addaption to head bolt possitioning I can get a 75mm bore and my initially aimed for 800cc with safety! 
Crank should be finished this week.

Will keep you informed.

 Ceramic bores, thats trick. Didn't Honda do that with their oval piston GP bike in the '80's?
Shame your putting knobbies on it. Would love to try it on a black track.

Post by: JulianM on 19.09. 2012 09:40
Morning,

Yep, ceramic and coated ally bores are used quite a lot these days including F1.  Makes sense really and the company I am using have a special 4 day turnround for racers, and 24 hour if desperate!  and only 40% extra cost!  

I do kind of wish it could be tested on track also, maybe I will stick a couple of road tyres on for fun one day.
I am building another bike wich will use 19" Maxxis Flat Track tyres so maybe pop these on for a giggle!
I will need to fit a road tyre to the back when I rolling road it anyway so maybe that will be the oportunity.

Regards,
Julian

Next job i'm in the middle of now is converting to a Yamaha FZR Clutch, including Cush Drive
Why an FZR?   Because I happened to just have a dismantled engine in my shed. 
BUT it is a really nice little light clutch and capable of about 130 break +  so will not struggle with my micky mouse figures,

Pics to follow.

Clutch conversion.

Thinking about the power etc and what to do I had a few concerns. My idea is to get it to 800cc with a CR of 10.5:1 and make a real torque monster. Hopefully achieving 60hp in the process.  So a standard or even uprated A10 clutch will not do!
A Suzuki GS or GT500 is an easy swap but both of these are about 50hp in stock form and I know from past playing that the GT550 clutch is not capable of much more than 60hp and with nowhere near the torque of an 800cc 4 stroke!!  So I cancelled these out.
I considered a Commando conversion but then realized I had a stripped Yamaha FZR750 engine in my stores. And the clutch on this is the same as that on the FZ1000, both of which out power my meager 60hp by about double!  It's also a nice 8 plate job weighing a lot less than my standard A10 clutch unit. Plus it has a cush drive, so the plan was to make it fit!

I am not going through the process here as it is not an easy conversion and not a recommendation unless you really need a super clutch.
Just here to show what I'm doing and why.

The two compared for size

One of my guys just came in with the wheels after painting the hubs and re-spoking so lots for me to do.
Added to the fact that I just went to collect my new crank so it's all coming together!

Little pic of the new crank against the old one.  
88mm Stroke and 3KG Lighter.  65% Balance Factor.
And the crank counter weight mass is in a much smaller diameter so the weight saving will be multiplied grately!

Hi, the rebuild is awesome. I have a question? wont there come a time when the power will blow the cases and barrel to bits - as these bikes were never designed for this, as a standard bottom end and barrels prove time and time again.

It is still brilliant engineering whatever your motive.
Title: Re: Julian's Scrambler build "Post 1"
Post by: JulianM on 22.10. 2012 09:10
Hi there,

Yep, there surely will come a time, but I "think" for now I have covered every post,  New designed Crank and rods, new pistons, new designed stronger barrels, "Wills Ring" head sealing so no gasket problems. Strengthened block and head studs.  I don't think the crank case will suffer too much and due to the heavy duty barrel hopefully this should add strength to the crank cases instead of the other way round.
I am aiming for 60hp which in my thinking is not a great deal, though "we shall see"    Am fairly confident all will stay together. It's not an endurance racer either, so I'm unlikely to hold it at full power for long.
For my day job I do this kind of thing all the time and some engines make a BSA look strong so get used to looking for weak spots. I think it will hold together for anything I will throw at it. 

Regards,
Crossed fingers Julian.
Title: Re: Julian's Scrambler build "Post 1"
Post by: The pirate on 22.10. 2012 12:05
I remember years ago, throwing on - clipons, very high comp pistons, bigger carby and changed the oil and went road racing, illegal road racing- the barrel parted company from the rest of the engine and a conrod tried to walk along the road - funny if it was not so expensive.

Had the same problem but mine went in my own yard!
Probably due to the idiot who assembled it and partly due to being crap anyway.  *smile*

Stripped the box on Saturday and am so happy I did.  If anyone tells you "i'm and engineer" built it all myself, and lives in Barrow in Furness  RUN FAST  cos he has three left hands  *smile* *smile*   All the good bits but my god was he a crap builder!!

Hi Bob,

Barrels not costed but will try to do a costing.  However probably a bit pricey.
Crank was about 1000 euros all in. Steel billet, 2 x heat treatment and then grinding, plus imaginative price of machining etc.
Just do it as and when you can afford the parts and forget the total cost  ;)  that's what I do  *smile* *smile*

 Yep, it can be frightening if you add it all up. I WAS keeping a log of the '57SS when racing, put it away once I got over $25000AU then add another $5000AU to transform it into the cafe on the road. That was just parts so in all with my labour it owes me about $50000  *eek*

Hi Julian,
The engine bits are looking great  ???? ????
Looking forward to seeing it come together
Going back a little to the clutch conversion it looks as if you have (or are going to) weld the splined Yam shaft to the BSA shaft adaptor??
If this is the case how will you keep it true while welding? It also leaves in place the weak link in the transmission, (in my opinion) the taper and key onto the mainshaft!!!

Even on standard bikes these can cause problems, mostly due to the tapers not being perfect or the nut not being tightened enough  *eek*
I normally lap the taper and then use loctite retaining grade ( the one that is supposed to eliminate splines press fits and keyways *eek* *eek*) and then tighten the nut with the air rattle gun
It can be a right Bast**d to get them off afterwards though  *conf*

Regards
John


Title: Re: Julian's Scrambler build "Post 1"
Post by: JulianM on 23.10. 2012 08:02
Hi John,

A good question and thanks for mentioning it.
The answer is thus.  The splined Yam shaft is big enough diameter for the taper and key and will be bored and taper cut to fit the crank.  Lapped as you do but I then heat the fitting with a hot air gun to "spit" hot  (till it is hot enough to fry spit) and then do as you do with an air hammer (with caution)  do the same with our hubs and halshafts and cured an age old problem with this easy fix.  Like you say though. Not easy to remove without heat  ;o)

The collar was bored out "line perfect" to 0.002" under, Heated and then dropped over the shaft to the correct depth in a little Jig.  Onced cooled it was tigged into place on the back.  The collar is only to hold the clutch bearing and does nothing else so no real load other than a little axial thrust to hold the bearing seated.  There was no warpage during welding, though I did check with the clock.

Regards,
Julian

PS.
I may just use this adaptor as a sample and make in one piece, depends on how happy I am when finished and how well it all lines up. I don't have much room in the primary cover as the clutch is quite thick.

Little Q for all you experts!   *smile*

Just rebuilding my SC gearbox and after scratching my head and banging it on the floor a few times to find out why the selector won't work properly, I find that it's been fitted with a reverse pattern sellector plate,  Why would you need this in an SC box?   I thought it was only fitted and "Needed" on the RR boxes due to the reversal caused by the rear sets?

Any thoughts?    Not that it worries me as it matters not where the gears are as long as I have them all  *smile* *smile*

Hello Julian

Just seen your thread , very interesting on what you are doing with your project. A quick point, have you considered using a rephased crankshaft ? it drastically reduces vibration (50-60%) if you use a 76 degree or 90 degree rephased crank. While one piston is stopped at tdc or bdc the other piston is at mid travel in the bore and at maximum speed , offsetting a lot of the vibration. just a thought , srm engineering in wales are now doing the cams to match so no difficulty on that front, its just the ignition thats a bit tricky to get correct but its possible with a bit of work.

regards.     
Title: Re: Julian's Scrambler build "Post 1"
Post by: JulianM on 26.10. 2012 06:39
Hi Bonny

Thanks for the input.
Yes, I did consider, but in my thinking it would stop it being a BSA if it were not a 360.  Some of the fun is the vibes and the sound etc.  I am also pretty sure that with the redesign of the crank and the lighter pistons etc it will keep the vibes within reasonable bounds.
I am also building two Laverda 750SFs at the same time, one absolutely stock and the other converted to 1034cc with bore and stroke at 87mm.
That one due to its pressed crank layout will be built up first as a "90? i.e.  270/450 and then changed back to a 360 as an experiment "like for like"  as most 90 conversions have been incorporated with many other changes so hard to tell what gains come from what exactly.  I will leave the Laverda as a 360 in the end also for the same reason as the BSA.   It has to sound like a Laverda and not a Ducati!   ;)


John,
Thanks for the offer but sorted now,
Flicked the selector fork to not line up with the dots but be in a similar place on the other side of the fork and hey presto.
Strange though but hey!  that's the fun of these old things I suppose!  (although that was not what I thought at 12.30am on Tuesday morning *conf*)

Another little update,
As I don't like constantly leaking pushed in exhausts, i decided to make some proper fixings.

So first step was to bore out the exhaust port to 40mm dia.

Latest update.

After 110 hours work the barrel is now completely finished other than Nikasil coating the bores, and its going in a box to be sent away for that today.  75mm bores in the end, as you can see 76 would be a no no without moving studs.  As it is the bores have been moved slightly to centralize on the 3 innermost studs. Grove at the top is for the gas filled "Wills Rings" instead of a head gasket.

Hi Muskrat,
Skirts short as the pistons I will be using are short skirt type also,  The barells are just as long as the bottom of the piston and no more. weight saving and as you say, rod notch saving too.
weighed the barell last night at 3.85kg  the std cast iron one one was 8.2 so just a little lighter than stock  *smile*

Looking forward to bolting it all together.

Regards and thanks all for the kind comments.

Julian,

If I haven't said it before, I am in total awe of your skills. So, you said to yourself, "No big deal, I can carve a set of barrels in my spare time from a solid chunk of aluminum."? I had to look twice at your user name to see the "M" after "Julian", because I would have been disturbed if it was a "G".

Muskrat,

Ya know, when we give our bikes gender, it's always female, as in "the old girl", "she", etc. Clearly, Julian likes his girl with short skirts.

Hi Richard,
Thank you for the compliment, however making most of these things is more an attitude than actually "difficult" as such.
Most people who can use a machine "could" make similar stuff; it's just going for it that makes the difference!  And policing the quality and the level to which you take it.
I find myself being a little "blasé" about these things because I am spoilt in my day job, we do these types of things all the time and making new cranks and rods etc., stroking engines and making new engine parts becomes common place. Then you forget just how lucky you are to be in a position to do all this fancy stuff.
I also have friends around me who can advise me and help when the going gets tough. 
I have the sad habit of immersing myself in engineering and engine design etc, for most of my spare time, even when in front of the TV I read tech books and design parts. Sad but true!  My life for the last 35 years has been so, and probably before that also. 
When you live, eat and breathe metalwork you do seem to look on things with a different perspective. 

Hopefully though my thread will show others how "easy" or should I say "possible" it is and not how hard it is.  If you can throw time at it and be lucky enough to have a fun toy shop to play in.

Flatted all mating surfaces on the big face plate,
Then cleaned and then epoxy painted the internals,
We use Glyptal Epoxy in all our engines as it really helps to keep things non porous and clean.
Never seen it come off either if applied to well prepared surfaces.

More bits to follow but loads of things still out for ceramic coating and Nikasil etc.
hope to see them before Christmas but will see.

I had wondered if you would move the stud spacings.
As others have said, this is lovely work. Can only imagine that kit and expertise.
If you can find the time to knock out any more of those barrels, count me in for a set!

With your crank and piston changes am interested to see what rod lengths you're opting for and compression planned for.
I'm still months away from having my 6" rod 358 cam bottom end together, but its decidedly amateur in comparison to your work.

Tim

Hi Tim, and Happy New Year!

Rod lengths will be standard with lowered piston crown height.  Pistons in manufacturing now with Arias.
CR will be 10.5:1 at least with 11 as a little thought in the back of my mind as I may use a 50/50 methanol - Petrol mix if I decide to be stupid  *smile* *smile*    But I "hope" 10.5:1 will prevail as it would be a lot more useable.  (read intelegent)

I did think of moving studs but decided that 777 was good enough engine size and it saves a lot of messing around.

Keep you informed when the barrel gets back from nikasil.  Soon as just been told it's finished.

Best regards,
Julian

I have said it before, and I will say it again,............Amazing! Any chance of a warts and all video of the first time attempt at starting? Didn't Porsche nikosil bores years ago? 1970's/80's? The only thing I don't like is the sealer you have coated inside the engine with. Clearly you have faith in your prep work to make it 'stick', but it would always be in the back of my mind that just maybe a bit had come loose. I am sure it will not in your case because you are a professional engineer and not a purveyor of gimmicky tat!
As for S.R.M. I am not in the least surprised you are impressed with them, personally, I don't know why people go anywhere else. Other than price they can't be beaten, and there is always a reason for that. Take pressure relief valves for example, they are dearer from them, but I know of two good engines that have gone for a burton due to cheaper copies being fitted, and one of them is mine! I fitted it because it came with the bike (750 Bonnie) and unlike S.R.M. ones it can't have been tested before it was sent to the customer. I must admit I do have an allegiance to them.............it's twenty odd years of fault free riding!
Title: Re: Julian's Scrambler build "Post 1"
Post by: JulianM on 22.01. 2013 15:27
Hi there,

I do understand your reluctance to embrace internal coatings etc but I have found prep to be everything once a good sealer is found.

We paint the internals of every single engine that we build here and meticulously clean the surfaces first so you "almost" don't need it. However it is nice to seal any porosity and any last tiny dirt particle from causing trouble.  To date we have never seen any paint come loose even after 10 years or so of use and even on Methanol burners!  I did some tests long ago with a painted part in petrol and it's still there on the shelf looking good and soacked in petrol, some 5 years later!     To be honest it's also a little bit of showmanship, it looks extremely nice when a customer comes in and sees how clean and nice their engine is, even on the inside!  Makes me feel all warm and fluffy inside  ;o)

As you say Julian, preparation is the thing, you clearly have faith in your prep! Sadly, a lot of so called professional engineers can't be trusted to pump a tyre up properly, never mind something as critical as that. My point was not so much the quality of the coating correctly applied, but the quality of the person who did it. There are very few people I would trust to do it, you would be amongst those I did trust!

it made me think when i first saw the pictures the other day about using it inside some porous J.A.P crankcases.I read the tech sheet which states its for use on the inside of machines and engines,but doesnt say that its resistant to castrol r40 or methanol,i take it you have'nt had any problems with the dope engines you've done ?,how did you mask the areas where you didnt need it ?,or did you machine it off ?cheers andy

Title: Re: Julian's Scrambler build "Post 1"
Post by: JulianM on 23.01. 2013 09:07
Hi Andy,

Yes, I would strongly reccomend it for that use!

We run 90/10  Methanol Toluene and if that won't remove it, well it is ok with me  ;o)
We use either R40 or M  which is R40 but modified for Methanol use.  No problems.

Generally I don't mask, I just paint carefully!  You can wipe faces off with thinners when it's wet if you need to.

Best regards,
Julian

Hi Jim,
Been busy on a lot of things including the BSA,
Just had a little baby also so the camera was swiped to go to hospital so a little bit of the engine build missing but not anything terribly exciting.
Picked up the paintwork from SRM in Wales on Wednesday and WOW!  Fantastic job!  Have a look.

Hia Julian, that's coming along nicely! Did you meet Heffin the painter at S.R.M.? He's a real nice bloke who's only concern is the finish. I spent a day there working on my engine late last year, and he spent all his breaks discussing my paint job and the tricks he has used in the past applying custom paints, most sprayers like to keep their stuff secret but he is very open about his methods, and he was most kind in his praise of my efforts...... He loves the whole process of spraying and it shows.
He has a trick up his sleeve when it comes to pinstriping that you now benifit from too!

Post by: JulianM on 16.03. 2013 08:36
Hi Guys very nice to see you are all paying attention and keeping me on my toes!  *smile*

No Dynamo, Ignition is a Mag and a fancy modern light weight (700g) all singing and dancing battery for the lights if/when used.

Have the usual breather arrangement and cork seal but nothing on the outer side of the idler shown in the pics.  My reckoning is that as it's only splash fed it isn't going to pressurize the dynamo drive housing and at worst it can "maybe" fill the cavity with oil and flood the same bearing that feeds it, if oil comes out that way then it will then go back that way due to a greater "head"  Think it will be ok unless I'm mistaken of course  *smile* *smile*

Wet sumping valve? NO! Not anywhere! I used the ss housing that you can see but even removed the internal ball that seals against the new pump. All internals removed and I will be fitting a ball valve that interferes with the kick start when in the off position for when not running.  Really don't like non return valves in comp/performance type engines.

Heffin.  Yes, what a nice bloke!  in fact I found all the guys that I met at SRM to be really interested in their company and helpful to the extreme!  SRM will go far with guys like that and probably the reason they have so far!

Off to play with my new bits now!  ;)

Is it your company or are you like my mate, recently retired from Cosworth, who replaced all the chrome on his old shovelhead Harley with stainless, using "off cuts" during his "tea breaks". You can plead the 5th on that  *smile*

Hi there,

No is the short answer,  Don't video anything as most of the time my work is a bit spontanious,  I am restoring / building three bikes at once and the limited time I get to work on them, my time is spread between jobs as well as dealing with phone calls for work etc. Even at weekends.
Videos would just use time i don't really have. Besides, I am no expert, so I will leave the vids to them.

I like doing pictures though  ;) ;)

 Lookin great mate, I too like the stand but wonder why it's on the wrong (don't think there is a wrong on that bike) side. Even left foot starting would be different with her leaning that way.
If only BSA had you working in the race & development shop.

I thought it might be something to do with the a*** first direction you race, I recall Ozzy speedway riders saying this, could be of course they spinning a yarn to cover a poor race.

Right hand side stand "Reason"?   Well actually yes,  but a little disgracefull to be honest!  *red* *red*

The best side to look at when parked is always the exhaust side right?  (or should I say Left) and the exhaust I have planned is hopefuly going to be quite trick looking.  so the bike will look best parked leant slightly to the right hand side.  Side stand on the right purely to look better when parked.  *roll*   

When standing on it the bike is almost vertical with the rear suspension compressed a little so you can actually kick it comfortably. (or should I say the kick is in a comfortable position as kicking a high comp 780cc motor is probably not going to be a joy)

Ha, I didn't take you for a show pony Julian. But then you'll need a leg like one to kick it, half way up a muddy gnarly hill.
I had to go back to page 1 to remind me of the pipes. Yes it will look good that side, but it will look great from any direction.

Ah!

That is where I recognise the red barrel from!  Looks cool by the way.

I had seen this page a year or so back and found it very interesting!
I almost went for the 89/90mm stroke also but thought i would get rather closer to the crank case for comfort so opted for 88mm.
I like the way you think!  very interesting project!

Will keep in touch and will try to meet up when over your way.

Best regards,
Julian
Title: Re: Julian's Scrambler build "Post 1"
Post by: Briz on 10.04. 2013 21:10
Yes, the 89mm stroke does often need some clearancing. The first one I did many years ago was on a plunger set of cases which needed no clearancing at all. But I did use a pair of steel Norvil capscrew rods which didn't have the upper shoulder of BSA & Triumph ally rods.
This time, we're making our own rods, so we should get them to clear OK. Dont really want to weaken the cases if we dont absolutely have to.
Title: Re: Julian's Scrambler build "Post 1"
Post by: JulianM on 15.04. 2013 07:45
Must say that now it's all assembled with my SRM Rods, I could have got another 2mm stroke in there I think without too much probs as I have at least 2.5mm all the way round so 1.5mm between rod and case "should" be ok unless I got a hell of a lot of crank flex.  
"Next time" *eek*  *smile*

Looking forwards to visiting and poking my nose into (pinching) your ideas   ;)

Just fitted the followers in the barrel and gapped the rings etc,
Now to the final assembly,

Just also arrived is my Scrambler kick start, this is a longer lever that has the pivot at the bottom and flicks round forward when not in use so if I fall off I don't get collected by the kickstart "hook"

Hi,

Yes, cam followers Stellite coated, reground with larger rad for a little faster velve opening and ceramic coated with some fancy stuff I am assured will stay on  *smile* *smile*  holes drilled for more oil aimed at hopefully the correct place.

These pistons are from Arias.
I use both Zzuhl and Arias depending on my mood.

Small update,

Clutch conversion finished!
I would not advise trying to use the FZR unit unless you like work!  It made me fight!  But I think it was worth it as the action is light and it should cope with an excess of 120hp so will laugh at my engine.

(https://www.a7a10.net/forum/proxy.php?request=http%3A%2F%2Fi3.photobucket.com%2Falbums%2Fy96%2Flagonda%2Fth_IMG_2142a_zps1cb901cc.jpg&hash=baf7934ceb0b9a19427db773315e9221ff8be390) (http://s3.photobucket.com/user/lagonda/media/IMG_2142a_zps1cb901cc.jpg.html)

Notice that the chain and sprockets are more than 10mm in from standard,  I removed the spacer from between primary cover and crankcase and then fitted the sprockets as close in as reasonably possible. Mainly to relieve stress on the end of the crank and gearbox shaft.  I also made a modern oil seal conversion for the gearbox output shaft.

Pistons and Block went on.
Notice the special HT block studs made with rolled threads, and little ARP HT nuts.

Did it in a non orthodox way by fitting the pistons into the bores up to the pin holes, fitting the circlip on the inner side first, then fitting the pin protruding a few mm and then dropping the whole lot onto the rods,  locate the rod eye by feel and push the pins in, circlips on and drop the lot down,  took me about 15 minutes from start to finish. Luck came back after the fight with the clutch  ;o)

Julian,

I love the look of copper & alloy, what are the two copper pipes visible over the primary case, are they oil pipes to a non standard oil tank? breather pipes?

gav
Title: Re: Julian's Scrambler build "Post 1"
Post by: muskrat on 25.04. 2013 08:57
Just brilliant. I've never put barrels on that way, but should be easier with light alloy jobs. Must be a pain starting the base nuts with the barrels sitting up a bit. I see the barrel skirts don't have cut outs for the rods. Are they short skirts? I luv short skirts  ;)
Cheers
Title: Re: Julian's Scrambler build "Post 1"
Post by: JulianM on 25.04. 2013 09:12
Morning guys,
Thanks for looking so closely!  makes me feel like you are trully interested.  *smile*

The copper pipe is simply a breather from the timed breather port,  a copper pipe was fitted to the crankcase hole, and joined to a mating copper pipe curved over the primary (that you can see)  it then does a loop to come back down and fit into the little hole above the chain sprocket.  Breathing and dripping any oil onto the chain.  (hopefully not too much as the oil tank breather also ends above the chain)

Locating the pins was actually a 30 second job although I too was expecting to fight a little. 
Due to the ring pressure and me locking the clutch I could slide the barrels into the right position in order to fit the nuts fairly easily, and all being new I could run them down with my fingers before tightening.

Complete job from checking pistons to final tightening was miraculously less than an hour.

No cut outs for the rods due to shorter barrel skirts, only down to bottom of piston at lowest point. and bigger bores giving more clearance.
And some luck  ;)

Hope to post more after the weekend.
Regards,
Julian

Little more work done these last few days,

Clutch fought me again, primarycover would not go on!  so now it's a 7 plate job with only about 120 bhp capacity   *smile*

Finalised the head build and fitted,  11.06:1 cr     so happy with that,  
Motocross kickstart fitted 25% loger than std,  (will eed that)
Still need to finish the rocker box etc but as that will be polished and i'm too lazy at the moment for that so I thought I would start on the exhaust.
Primaries finished and within 5mm in length of each other and tucked in very tight.  Very pleased!

Hi Jim,

Used Spitfire / GS a cam after much consultation but had the followers reground with a flatter 1 3/4" radius for faster opening.

Am fairly sure this will work as good as any.

Morning Neil,

Have a quick look at page 3 of this topic and about half way down you will see the modifications I did to the exhaust ports and flanges, I hate the standard push in and hope arrangement so made bolt on flanges with small locators so they will just "snap" in and bolt up, makes life easier and less leaky  *smile*

Good observation though!  impressed!

Bit more work in the shed recently.

Rocker cover cleaned and lightly polished, Built up and fitted,  tasety alloy covers fitted,
Ignition leads fitted, (the right way round)  *smiley4*
Carbs and manifolds fitted, Choke slide cut down and Araldited into the main slide.
Carb bell mouths and filters fitted,
Fuel taps fitted and fuel lines made and fitted,
Head light moved slightly closer to the bars,
Getting closer to the big day but off to Italy for a week now so nothing more for a couple of weeks.

Looks the bees knees Julian, can't wait to hear and hopefully see her burst into life! pray tell how you're going to protect your nuts from the oil tank cap will the seat cover it and hinge I know you'll have thought that out so I wait with baited breath . Just reminded me of the Dunstall dominator/Triton oil cap ,which along with the triumph tank grid  rendered quite a few riders hors d'combat in the child rearing department . best wishes BobH

Hi Bob,
The seat covers it and is very fast to remove, just pull on a "pip pin" and the seat removes backward.  Steel uder side so should protect balls hopefully  :o)

New scrambles kickstart, polished and chromed and then wrapped with string which was soaked in varnish, left to dry and then re-varnished for both protection and to make it stick to the kickstart.

New X link Gold chain fitted, a bit wide to be honest but looks cool!
Chain tensioner pad needs modifying to sit correctly.

Tyre clearance is minimal as I had to bring the wheel more forward than ideal due to not wanting to use a half link in the chain.

However I can make just as many cockups as others.

Just tightening the fork spindle pinch bolts and Crack!!!   Over tightened without thinking and snapped one of the sections!
Now I have to remove the fork leg and weld it up before re-polishing and fitting!  Half a days work just ***** away!  *sad2*
Kicking myself!

Hi there,

Well even with the 60t rear sprocket I calculated that it will still pull 85 MPH @ 6000 revs in top.   What do I do?    can't gear it much lower  *smile* *smile*    or Higher!

Wheelie machine?   Yeeehhhhhh   *eek* *smile*

Made the exhaust last night and this morning,  Made a tapered tube from collector back to reverse cone.  Turned out just as I hoped,
The complete exhaust will be satin black ceramic coated.  

What do you think?

Post by: JulianM on 25.09. 2013 08:33

Morning all,
Had some luck yesterday,
Big startup, oils filled, engine oil primed, fuel tank semi filled, carbs then flooded and Kick, Brrrr up, Kicked again, and again, and again but would not catch, just firing slightly.
So after about an hour of checking and double checking and half killing myself (remember this is 780cc and 11:1 cr) we towed it up the yard, after a while it was running fine on very small throttle openings, let it warm up fully and running extremely well for "guestimated" settings. (need to re set the ignition though as it only runs in fully advanced position)
Now fires up within a few kicks from cold but is still extremely lean I think as it really does not like any throttle when cold.  Idles perfectly though and sounds F-----g amazing!  But also LOUD!!!     Video to follow later, maybe today.

Regards,
Julian

At last downloaded the vids.

Primed the oil, re-fitted the pressure regulator, kicked it until oil circulated into the return, re fitted the plugs and seat and on with the vid.  Was extremely lucky with the setup Guessing!

Post by: JulianM on 10.10. 2013 08:15
Have I ridden it yet? Well of course I had to give it a little test didn't I :o)

Once warm it runs very well indeed, still very lean so I have to use the throttle lightly but it goes extremely well and pulls very strongly even at small throttle openings. Rides fantastically well and the clutch is very smooth although slips if I use more than half throttle but I think that that is because I stupidly used 80/90 gear oil in the primary and remember now that the Yam clutch is designed for engine oil. I will change it to ATF for optimal grip I think. Gearing seems perfect and theoretically will do 90mph @ 7k which is easily fast enough!

Will keep you all informed on final setups and rolling road when I get round to it.

Regards to all and big thanks for the encouragement, it makes a massive difference having you all behind a build like this.

Julian

Jim,
I will certainly try!  It would really be a great event to see it run the hill !    With someone good on it rather than me being a knob on a tasty bike   *smile* *smile*

Clutch slip finally solved and turned out it was my fault.
When I shortened the basket and removed a plate etc I thought I had shortened and checked the spring cups enough,  I hadn't, the cups were just touching on the fillet radii at the bottom of the towers for the centre spring bolts and thus holding the plates from full engagement.
Shortened the cups, (lip for springs disappeared) bored the cups with milling cutter 1mm larger to create a new lip inside, dropped in a tight fitting bored out steel washer and hey presto, all working after making a small spacers to hold the spring bolts from bottoming and causing the springs to go coil bound.
Grippy and easy clutch now working well.

Just leaves a bit of jetting to do and maybe will get the mag converted to give auto advance etc, a bit risky kicking this into life at the mo.  You have to remember it's all or nothing. and it needs much more fuel also.

Will keep you informed of my new business plans,

Regards,
Julian

PS,
I have a rider for Red Marley,
A mate in the UK runs a specialist ally panel shop and one of his guys races classic bikes,
I am going to drop over my Metisse for him to race and he will also then get to use them both at Red Marley.
Keep you posted.

Hi Guys,
Been away for a while, some changes here in Belgium.
for some time now I have been unhappy with the situation at my old company and it came to a head mid last year and I attempted a takeover with the aid of a friend. Unfortunately, after a promising start the bid failed and we had to pull out of the deal before we were left with a lemon.
Plan B went into action last November.  I have now started up my own company with no partners this time. Just a great work team and some great customers and friends.
Here is a link to some pics of our opening doo last Sunday.

The web site  - www.historiccompetitionservices.be -  should be up and running in the next couple of days and if anyone is in the neighbourhood then just come on down and visit. You will be made more than welcome.  This is motorhead Valhalla!!!  and I wish i had done it 8 years ago.

Glad to be back.

G'day Julian.
My grandad used to say "If you love your work you'll never work a day in your life". It looks more like a passion to you. Best of luck with the new venture. I didn't see the scrambler there.
Cheers

No doubt that bike is a stunning testament to your abilities!  *respect*

The big question is now that you have your own business, how many forum members orders will it take to secure an alloy barrel ...
A small batch would go a long way  *wink2*

Pencil me down for one  *loveit*

The new business looks very good, Julian.  Please keep us posted on any 'open days' you might plan to hold.  Antwerp is not too far from us in the SE of England and there's the added attraction of great Belgian beer to prompt a trip across the channel.
Good luck with the work.

Hi all,

Big thanks for the heads up,

The scrambler is in the showroom looking cool and shining brightly but no time to play with it i'm afraid.
The business is cars only so no intentions to do any ally bike barrels at the moment. The bikes stay as my hobby so as not to confuse things.
We will have many open days etc as we have a 1000sq/m car park to ourselves so plan to have ride in / drive in days regularly for both cars and bikes to meet and have fun.
Will keep you informed and you are welcome to arrange something your selves if you feel inclined.
Keep an eye on the web site opening soon.

Regards,
Julian

Fantastic. Some of us (finger pointing at self) only dream of such things. I already have a very clever name of the TV show that will soon be coming to us from Historic Car Services. Tell me if it's not inspired. "Julian's Garage."

Small update.

Some things I wasn’t happy with so have set about changing.

A, it looked too modern.
So lowering the back an inch.

B, didn’t like the iron hubs.
Found an alloy quick disconnect rear hub. Bought an alloy twin leading shoe front hub complete.

C, heavy wheels
Bought a 2.5 inch x 19 morad rim
And 1.9” x 21 front
Stainless spokes and some lovely shenko trials tyres.

D, forks were soft
Sending away to Maxton for modern internals.

E, oil tap buggs me
Redesign it.

F, oil tank too small
Remake it bigger and better.

G.
Use it

Keep you posted
Jules

Hi All,

I have missed you   *smile*

Lots happening at work so real busy but thought I would post a final pic of the last mods done to make it look a little more period correct.
21" front wheel, twin leading front brake, trials tyres, lower ride hight.
Now sadly gone to new pastures as I was offered a good price at the right time.  All things must move on occasionally.

Hope to chat again soon,
Julian

PS, one of my colegues has a cool A10 custom, I will get him to join.

G'day Julian, we have missed you too.
Don't leave it so long for next visit (3 years)
Wow she looks a weapon. Luv the pipes. What hub is on the front? Looks like a converted Ariel alloy hub. Has she been run in anger on a track?
Cheers
