It's cheaper to buy one than to purchase the parts and build it yourself 😁

I believe the quality of chrome was inconsistent, some flanked off within months. Keep an eye on it, it may be fine.

Run the front hub as it is, but check it regularly. The rear hub would have been chrome too, and has been relined. Inmotion used to do it, not sure if they still do.

IRC tube type is a very good so round tyre, perfectly suited to twin shocks. Don't worry about whether it's suited to complement the front.

I don’t think that the wear of the cam follower should affect the timing once set correctly, but I’d really like to replace with a ‘proper’ quality set if anyone knows where I can get some! Ware will affect timing, and the points were always poor quality.

Richard Allan and Jim Williams were doing a glass one. Later mono ones are very similar, but narrower.

Doubt it will stay on the rim without resorting to cutting it.

Define "bling"

Check towbar and car specs , I'd be very surprised if this is legal and in the event of an accident may invalidate your insurance.

Check your getting a good flow from the tank as it could be debris in the tank.

Speak to people in the area with trials bikes and find a mot test station that understands trials bikes. Agree with everything above, also check wheel bearing have no play, spokes all tensioned, swinging arm no play, steering no play but adjusted to move with no resistance. You do not need a reflector, but stick one on. Tyres should be properly inflated (not trials pressures) no cracks or signs of deterioration, directional arrows should be correct orientation (or removed)

Worth checking if it's already registered, DVLA have / had an off road registration service so your bikes on the system of it gets stolen. I used this on another bike and discovered it was already registered. I got the original number back for £25.

https://www.dvlaadvice.co.uk/about.htm I have used this company to get an age related plate. They are based on Bristol.

Cut down an old plug and use it to block the plug hole.

I'm curious how you know you have a 50% contact ? If you have stripped the cylinder off to check, what symptoms prompted this ? Personally, on an engine of that era, I would only ever use semi synthetic at 50:1. Generally once you have used about 5l of fuel, the piston should be fairly bedded in.

I believe any dampness in the timing cover causes slight rusting on the cam, this quickly wears the heal of the cam throwing the timing out.

I changed the "sealed for life" gear box oil in a vw at 100k miles, and it looked fine .....

Atf in clutch is good, not sure of quantity .

Virtual all clutches do this, type and quantity of oil has a bearing, but it is normal. Lots of different ways to free it off (and it will free off 99% of the time) Mins is start and warm engine, have plenty of space, push bike and slip it into gear, ride around with clutch pulled in. Maybe a bit of back brake too.

😂😂😂😂 we've all been there.

600g's, just cheched.

How much has brexit added to the cost ?
