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.

My apologies, it seems that model has the seal inboard of the main bearing on the drive and that's the side that could be causing your problem. But you'd do both anyway. Still simple enough for a competent mechanic.

Seals can easily be changed from "outside" - any competent mechanic should be able to do the job for you in short order, if they obtain rhe right puller.

You have a valid point but it highlights something: In my heyday I could buy a bike pretty much the same as was used in the world rounds and I could use the annual performance improvements provided as they were appropriate for the sections I rode. The bikes used today at world level would be pretty much unrideable by me now or by today's equivalent of me in my twenties.

Someone on here recommended using Heldite on the spoke nipples. I used it successfully on those that were leaking and reckon that you could just about do away with the rim tape. Perhaps I'll experiment next time I have a suitable rim.

I think that would accord with convention.

Perhaps I should have added the words, as I had inferred, to my second last sentence, "in the UK".

As a rider from the classic era who rode a Rev 3 for twelve years I can say you'll have no problems getting round tight turns using an old fashioned riding style on that bike. I have not ridden an Evo though.

I check the filter at least every time I wash the bike so putting any old bit of poly bag or whatever over the intake is no hardship. How would you know the permanent cover had worked unless you looked? No effort saved then.

I tend to agree with Hillary and at one time would have been horrified that we didn't have a round but now, frankly, am not too bothered. I can't summon up enough interest in WTC to read the results and there was a time when I would never have thought I could say that. What we can be sure of is that lack of a round will have absolutely no effect on entries at the many dozens, or more, of trials run each weekend involving hundreds, if not thousands, of riders, nor will it affect sales of new bikes, or anyone's enthusiasm for the sport. Does this make WTC irrrelevant?

I suppose the opportunities for drowning the bike in seawater over 110 degrees C must be fairly limited so not too much of a problem.

Irregular spark - could be the trigger coils in need of replacement.

I doubt whether I could easily find the print of the e-mail after all these years but seem to recall that they felt the full synthetic was not as suitable.

Silkolene recommended I use semisynthetic in air cooled 70's motor when I asked their advice. Various ratios suggested according to terrain/use but 50:1 for what we do. Works fine with no sign of excessive smoke.

No wonder we think the Americans are profligate. With reference to the photo above, and to paraphrase Crocodile Dundee, "That's not a minivan, this is a minivan" 128.9 inch overall length They were occasionally used to transport bikes but the pickup version was more commonly used for such (sometimes two bikes). Should have been delivered with a complimentary pair of wellington boots though☺

Dry the filter out on a radiator (or even use a hairdryer) and get out tomorrow! Let us know how it goes.

By the time seals need replacing then I find it worth stripping the forks to clean them - a lot of black stuff comes out. I then use the old seal to drive the new one in.

Whilst the coolant may be OK you are dealing with temperatures way below what most of us have experience of. If you are that worried then the obvious remedy is to take a few seconds and drain the fluid completely for transit.
