Shouldn't be a problem. You may need a gasket for the casing as well, they tend to stick and tear. By sheer chance I found this while looking for something else Oil

I think there are some formal parameters to define such a bike but can't recall where I saw them. I do, however, remember that when indicators became a requirement in the UK "trail bikes" (they were the ones people were worried about) were excused this and also the mirror requirement if my memory is correct. Probably covered in Construction and Use Regs, which incidentally render illegal almost every new road bike with a plastic stick, instead of a mudguard, to carry the rear numberplate.

If I had a fiver for every youth that I've seen leave the sport when adult life in the shape of girls, further education, drink etc came along then did not return for twenty years, if at all, then I'd be a lot better off than I am.

I thought EU regs permitted not having indicators on a machine intended for offroad use?

Duckswax looks excellent but softening of the leather is not really what you want on a trials boot worn to protect from injury.

Must be the only thing for which BMW dealers are the cheapest source?

I'd be intrigued to know what you think does cause fourstroking, if not a rich mixture.

It's easy to redo. But I have not had to tighten a spoke in at least the last decade (and, yes, my wheels are true) . But what happens to a rim tape solution if you are careless when changing a tyre? Choose your pIck, as they say.

300 degrees from what? How many turns out is it. I'm guessing, at that age, it may have been lying a while in which case the carb may need a better clean than you have given it in order to get gunge out the passages.

I've some sympathy with that view Breagh but, because I am an enthusiast, do feel that trials should have a world championship, but perhaps not what we've actually got. You are old enough to remember the estimable Ralph Venables and to have read his weekly thoughts; I suppose we youths regarded him as an old reactionary (much as some will see us now) but as I recall he predicted that trials would become the flea circus it has.

I don't know if anybody ever fully sorted the caburetion on these. I seem to recall that starting, especially when warm, was a perennial problem.

When I first took an interest, in the Sixties. Before your "trials" time?

I've never heard of it happening on a modern bike but have known the perforated tube in a silencer to break and fall at an angle such as to restrict the exhaust flow, thus cutting the power.

You are, as was the SSDT, to my recollection. Variety is the spice of life.

Edward Turner will be going well in to the red, spinning in his grave?

No wonder, lead in petrol was banned nearly twenty years ago. It was better stuff though (for vehicles anyway) - someone dragged a Scorpa out the shed recently and it fired up second kick on what had been lying in the tank.

Surely an enthusiastic importer should not have to be bodging up the exhaust on a machine produced in 2018 by one of the world's biggest manufacturing nations? While that test was not carried out to the FIM standard it doesn't lead me to think that the bike would pass such a test, which involves full throttle.

It's hardly a rumour - you only have to listen to the videos to hear the hideous racket (compared to other four strokes on video) . "Locals" don't care about meter readings, just what they can hear.

Trying to message you OTF but you can't receive. Can you PM me?

Possibly, it has been known for people to use a half link to keep the wheelbase short. There's an easy way to find out - see how much slack there is if you align the chain as if the half link either was not there or was a full link - tie the links together with wire for this static experiment.

Lot's of the newer stuff is '59 BSAs?

I'd be interested to see a picture of this, or a link to supplier's photo.

Sounds about right if, due to inexperience, you are slamming the front end down.

Back in the mists of time this was tried, with the involvement of some high profile British Olympians if I recall correctly. Perhaps the electric aspect and the fact that sections nowadays could be much more spectacular than in the twinshock era might give a higher chance of success. Whether that be a good or bad thing is a moot point.

You're not going to get the optimum performance unless you have the barrel plated to suit the piston. i'm surprised anyone has taken on the job of plating without having the piston also.
