i suspect you might have blown the head gasket when it overheated

IRC still do tubed type tyres with exelent grip

I would have thought that 28 was a bit big, but give it a try it will probably close as is.

If the same as mine, where they go into the hub they are M6. Bear in mind though that they are special shouldered bolts

I've just had a stator for a Fantic rewound at West Country Windings and they seemed very efficient, not fitted it yet but my brother had the same done some years ago and its still working

like you said it works the reverse way, the springs push the plates out to the pressure plate on the end, when operated the pressure plate pushes toward the engine and releases the clutch. I've only ridden a few 4RT's and found the clutch to be of a light action so I would compare yours to others before adjusting the springs. It may be you have another issue

Try central wheels

No, it does not matter, have rotated one on its centre and randomly put one on a villiers engine

they do appear to be equi-spaced. I think you will have to check timing after fixing them. You will need a dti to find top dead centre and then the required firing point so that you can mark the flywheel if it isn't already. The copper coloured coils are just for lighting and should be removed if you are not thinking of adding lights

check the ignition using a strobe. They don't normally alter, but obviously someone could have built it up and hot checked the ignition. The system is identical to the suzuki singles of the same era. The flywheel is in 2 pieces as it has an extra weight added for trialing

yes, preferably a much cheaper one with slightly less grip so we can ease the sections back a little too

Thinking about tyres having replaced mine in the last few months, what are the thoughts on having a cheaper control tyre for classic events?

Just had a new very expensive X-Lite front and does anyone else remove the moulding flash like I do? I was surprised how much came off much more than recent IRC rear

Try retarding the ignition

Not on a modern bike, but I use it in my Greeves as it did have a tendency to seize and it's the most tenacious of oils.

It would run, but with very little power

It was running last year, John Penny is the owner and a nice guy but runs it as a sideline. Join the Armstrong/CCM trials group on facebook and ask the question there, it's a useful source of information too

I wouldn't bother. From experience the weight is more suited to none clutch use as it prevents the engine stalling. When I firtted the electronis ignition to my greeves trials bike, I left the weight off thinking being used to riding bikes with virtually none I would be fine, but it was almost unrideable. I was gutted to have to add over a kilo of weight to the bike as I've spent a lot of time and effort reducing it's overall mass

A friend had one of these and he fitted slightly longer shocks which steeped the head angle and increased the ground clearence

Have you tried Central Wheel?

It is a Rotax, but that might not help you a lot There was a guy on ebay breaking them

There's a good chance that the ossa fork stantions etc will fit nicely into the RL bottoms

As long as the rims match ie both not shouldered, and have same number of spokes you should be OK. be wary of used rims, they are usually knackered

My experience with small bikes suggests the carb could still be blocked, the jets are tiny and take some clearing out as do the airways in the carb itself. Also if it has a dellorto carb, these often have 2 slow running jets in the same boss. i think your clutch issue is just that this bike could have come with a centrifugal clutch from new
