Title: Tips for running in a rebuild and long distance biking
Post by: owain on 11.06. 2017 17:20
First of all I need to thank Beezermacc for thick washer that he sent me for the ATD unit. Cheers!.

Righto, I've done a mechanical restoration on my 1950 BSA A10 sidecar outfit and that another BSA is back on the road after 50 years of sitting in a shed  *smile*. I'm aiming to motorcycle from Helsingborg, Sweden to Llandudno, Wales at the end of next week and I'm wondering if anyone has any tips on a) running in the newly rebuilt engine and b) if anyone has any tips from their own riding experience.

My current rough plan is to spend 2 days testing the motorcycle out in the Swedish countryside (do about 50 miles on it) and then change the engine oil for the 900 mile trip to Wales...then probably change the oil again there?

As far as preparing the long ride, I'm just taking some essential tools (spanners, sockets, screwdrivers) and a few spare nuts and bolts...

I'm leaving it to experienced long-distance A10ers to give advice as to what to bring. I do have a question, though. Are you riding back, as well?

@RichardL Yep, the plan is spend a few weeks holiday in Wales before motorcycling back to Sweden :)

Looks like Aberystwyth (thus, SRM) is about 3 hours from Llandudno. The former is a place I would definately want to visit on my trip to Wales if I'd just finished a 900 mile ride and about to start another.

Don't forget a spare inner tube. I assume you are running in new pistons and big ends. It's the usual stuff than. Don't labour the engine at low revs. Let it speed up on the downhills, slow down on the uphills. Don't try and run in on synthetic oil. Use a straight oil or a regular multigrade. Shut the throttle once in a while - it lets the thrust face of the pistons get a little extra lube. Enjoy the trip. As they say, if a bike will do 30 miles, it will do 300 miles. Just do that 3 times!

To break in new rings, (or glazed up bores) find a quiet straight road, get into top gear with low revs and accelerate up to high revs.
Change the oil after a few miles. Now, no labouring, extended idling or high revs for 500 miles. Change the oil again, it's false economy to extend oil changes.
If the engine starts first kick hot or cold (and doesn't leak a lot of oil) *conf* you have done a good job of it and should be able to do a long trip with confidence.
As Black Sheep says, take a spare tube. And levers and patch kit and a pump. I take a tool kit with WW spanners, screwdrivers, pliers, duct tape and tie wire.
 Log onto this forum if you breakdown, we are everywhere now and could assist you!   *smile* Take it easy and don't let them push you on the highways.  *eek*
Finally, enjoy the trip.
Cheers Peter

Rule #1 as others have said don't labor it. Warm up is essential but not too long (2-3 minutes). Do a few 50 mile runs then change the oil. Usually a head re-torque but if it ain't leaking, re do tappets and go for it.
Cheers

Defo a good head retorquing after a few heat cycles. I'd be tempted to pack a second annealed head gasket if you don't get to put too many miles on prior. But then I've previously been unlucky in that department.

Owain, I'm interested in the route you will be taking. A Google search shows a route of about 1900 kms ea way with at least two long ferry rides. That route is partly thru Western Europe.
Aside from packing lots of tools and spares, especially ignition related items(seems to be the weak point on old bikes) some hot shot hand warmers can be a lifesaver on high mountain passes, should there be any on your route.

Ok, no labouring the engine. It might be a bit hard with this one as it'll be pulling a sidecar the entire way. Otherwise, I'll try to take it easy with no high revs or prolonged idling. I'm putting together an extensive tool kit now, so I should be able to cope with most eventualities...except for a blown head gasket :/. Spare inner tube is a good idea. I'll put it on the list.

@worntorn, I'm trying to take the most direct route possible with as many ferries as possible so that the motorcycle I won't be riding the motorcycle non-stop for more than 2-3hrs + I think my dog needs a break as well from sitting in the sidecar ;). Current route is looking like this:
Day 1: Helsingborg (Sweden) to Helsingør (Denmark) and take the E47 all the way down to Rødbyhavn (about a 2hr ride). Take the ferry from Rødbyhavn to Puttgarden (Germany). Ride on autobahn 1 from Puttgarden to Bremen (about a 3hr ride). Sleep.

Day 2: Ride from Bremen to Amsterdam (Holland) with a pit stop along the way (about 3.5hrs). Have a cup of tea with a friend in Amsterdam. Then get onto the boat from Hook of Holland to Harwich (England). Get off the boat at Harwich and stay at a B&B somewhere.

Day 3: Possibly ride to Cardiff (S.Wales) and stay with a friend or ride directly to North Wales (M1/M6/A55)...Possibly jumping onto the A5 at Shrewsbury instead.

Hi,
I would try and avoid the motorways as much as possible
My experiences on UK motorways is that the minimum speed is 60+ MPH
Trucks hog the "slow" lane and often travel nose to tail  *sad2* *eek*

Good Luck
John

How would you drive if you were limited to 90k? Yes you would also be nose to tail.

If possible I would recommend 500 miles of testing  *whistle* I say this as despite my best efforts I had a few serious problems surface after quite a few hours of running in  *problem* (blown head gasket due to duff torque wrench, gearbox bush failure due to duff part supplied etc).

Avoid high revs obviously and dont labour the engine as has been said.

If you rebuilt it properly it will get you there and back no problem

As for what to take?

Lots and lots of cash cos if it does go wrong you will need it :)

i'd prefer to do at least a couple of hundred without the sidecar to ease the load on your new bottom end. the problem is the bottom end wants a peaceful low-load start to life and the rings want some serious work to bed in. so compromise is one-third to two-thirds throttle and vary your revs to help the rings, especially for the first 100 miles. so no steady-speed motorway riding. oil changes at 50, 500 and 1500 miles. and all of the above.
sounds like a fun trip coming up. has your dog got a helmet and googles like this photo? (sorry forum, i think its a b33 or M20 etc)

Awesome tips guys, I just got back from the garage now after fixing (I hope) an oil leak from the timing cover. Hoping to stick fresh tyres on the bike and get it through it's MOT on friday so I can start running it in. Will hopefully be out all weekend on it!.

As for the dog helmet....Of course, can't let the little bugger go deaf ;)

When you visit Llandudno, make sure you take the orme tramway, get to see some beautiful sites there, spent my teenage years on the north coast of Wales and then Telford by Shrewsbury. Always tell my wife how beautiful Wales is and one day will take her.

Hope you will have a great time and take plenty of pictures!
