    Replacing the carburettor sorted this out. I bought a BVF copy/clone from Poland (£45 including post). Started straight up and ran perfectly. The quality is pretty dire though (as you might expect for the money). Longer term I will be looking to put a Mikuni on it.

    Thanks Rob, Yes, I believe the spacer method would work equally well. I just got a 100mm M10 bolt and screwed it in, popped straight off.

    Well, I changed the generator side seal….. No improvement, so I got myself a clutch puller and an engine locker and changed the clutch side seal. Guess what…. no improvement.

    I will revisit the carb and manifold, although I thought I had been pretty thorough the first time. Perhaps I will try a different carburettor if I can get my hands on something that fits. The only thing I can add is that by trial and error I discovered that if I drop the throttle needle right down to it’s lowest position (top notch – weakest?) then it will run at a lower tickover (2000 rpm) but still if I blip it revs up and takes ages to settle back down to 2000.

    At least I have eliminated the seals as the cause, I know I have a good set of seals in and I won’t feel as daunted at tackling the job on other bikes in the future.

    That’s brilliant. Thanks very much Peter, that is exactly what I needed. I have ordered the seal and will see how it goes… If there’s no improvement I will tackle the drive side which I guess needs a clutch puller.
    Thanks again,
    Pete.
