I had the brainwave of fitting castors to my bike hoist. I can now move it to get easy access to either side of my shed.  *good3*

Mind you, it's three inches higher now. The ramp is steeper. I walked it on in first gear as I normally do.

My little seig mill dropped its lunch the other day.
Pulling it to bits today and found a string of triacs or IGBT's have the guts blown out of them.
With any luck it will just be the semi conductors and not all the clever bits.
This could get expensive.
cheers

Any ideas about why that has happened? A full short somewhere maybe?

V50 gearbox is out and gone off in the post for specialist attention. Only took around 2 hrs to drop the motor/trans, must be from all of the practice - and it's a lot easier to manage than a big block.

I was wondering if having castors on the hoist might be a problem. Although two of the castors have a brake, it doesn't seem very effective. The hoist will tend to move if I have to push hard on some part of the bike. I've been thinking about making 4 of these jacks.

The issue is that when the hoist is against one side of the shed, I will not be able to get at the jacks on that side.

And then I thought, what about having a chain and sprocket arrangement so I can lower and raise the jacks from an accessible position.

Later.
Actually I'd only need to pair the jacks with a (bicycle type) chain across the hoist, so when one is turned it revolves the other side...Simples! Chain and suitable sprockets are available on Ebay for a reasonable cost.

Struggling with that one - seems like looking for a problem to fit a solution. If the jacks are joined by chain, how do you move them independently to account for floor level irregularities depending where the hoist is? You're bound to end up with it rocking on three. And with two jacks down, how is the other half of the hoist going to move anyway? Just my thoughts.

The floor of my shed is flat. It's T&G boards.
My thinkings were:
1) The hoist is not going to keep still while I work on the bike.
2) The castors, although rubber-tyred are marking the floor.
3) I'm worried, (probably unnecessarily) about my blobbing welding. I don't wish to open the shed door one day to find my bike laying on the floor, with the hoist on top of it.

The chain idea would just pair up jacks on opposite sides of the hoist.

My mate finally got his cylindrical grinder sorted, so was able to grind the existing cam off the distributor for my project (as members may recall, I decided to modify a distributor to 60* to replace the magneto currently fitted as I%u2019m having extreme difficulty starting it). 1,000cc and just under 9:1 compression means it goes over TDC too slowly for a decent spark, even with the front cylinder decompressed.
I%u2019d already made the replacement cam so fitted that today. Next job is to see whether the rotor arm will align with the dist cap pickups or whether I have to make / modify the rotor arm as well (remember the cap pickups are set 180* apart). I%u2019ve not yet cut the rotor arm locating slot in the cam, as I%u2019m hoping I may be able to fudge the location and use a standard arm. Whatever, the rotor arm / cam location is going to be critical. Onwards and upwards as they say....

edit/ update.
Last night, after a bit of fiddling about, came to the conclusion the rotor arm would service both dist cap poles with the new cam, so this morning (Sunday) I machined the locating slot for the arm. Just waiting now on delivery of an m4 allen screw to lock the bevel gear to the shaft and then I can fit it to the bike and time it up. Got allen screws / bolts coming out of my ears in imperial and metric, some up to 200mm long - but no m4!

Great day out on the A10. Met up with 2 mates with alternative marque vertical twins of the 650 cc persuasion. Blasted off to a cider farm in deepest darkest Somerset. Had a most enjoyable time catching up whilst maintaining social distancing of course. Was nearly dry by the time i got back! Needless to say the bike ran like a dream,apart from the piston slap, shocking front end, brakes etc. All of which is irrelevant 'cos it got me there and back in great style, started when asked and didn't let me down. A happy and welcome day after all the lockdown misery.

Well at long last I got the bike out of the garage ,sorted out the HT leads one od which I'd pulled out of the maggy connection when I was fitting the ski slope last week . Dried out the oil and was surprised to find a thin shard of carbon in the connection has the connections  haven't been disturbed for over 10 yrs it must have come of the carbon brush which was still serviceable , anyway once done I turned my attention to the other and after a break flooded the carb and gave her a big kick second time bingo ran pretty damn good , she's done this for as long as she's been back on the road so once again can't help but say that the refurb done to the maggy  was  some of the best money I've spent on the bike . next week out for my first ride of this year, watch this space!!

Yep, happy with my mag for sure.

I got most of my Guzzi V50 back together at the weekend. Outside of that I've still not started an engine or turned a wheel since lock down commenced here in the UK.

i got the rrt2 out and took the kick start quadrant out to put back in the std gearbox because it is adapted for the Suzuki kickstart. I might have discovered why some kickstarts jam even though they have the correct quadrant and pinion. with both gearboxes on the bench I started to have a look why mine was sometimes jamming. resulting in pulling the clutch in to free it up. I noticed the flat bit before the first tooth on the quadrant could jam on the top of a tooth on the pinion . I tried another quadrant and noticed that the flat bit before the first tooth touched a tooth on the pinion pushing it forward ready for the first quadrant tooth to fully engage with the pinion. I tried 5 quadrants and noticed they had more chance of the flat bit jamming on the top of the pinion tooth the more the shafts were worn. so to have a worn kicker shaft and worn steel bushes the more chance it has to jam up. I think I will grind the lead bit down so it can't jam on the top of a tooth and try it out tomorrow. thankyou for listening have a nice time
