Be worth spraying wd40 around the crankcase halves Gary when it's running. 
did you use sealant on the halves when rebuilding?

Hmm, I recently had a theory about using sealant, I know we all have done, but for the last fifteen years or so, every time I rebuilt the S1 I used sealant and let it semi harden before torqueing up the cases.
Each time, the generator side crank seal popped out sometime later, I think that letting it semi harden means it can't squeeze out of the joint effectively making a gasket and reducing the clamping force on the oil seals.
If lots was applied and left to cure before clamping up, I suppose it could lead to leaks in the casings, anyone else had strange problems that could be attributed to this sort of thing?

A crankcase half is so well machined that you could almost do without the sealant.The finest even smear on all of the crankcase gasket face and then assemble immediately and torque in the correct sequence will always work.The temptation is to put just that bit more on to be sure,but that is unneccessary.Also if the crankcases are not a close fit there are other potential risks to main bearings and gearbox bearings.

right getting closer to this now
the bike rides and starts,i have tried it with baffles out and no different
the bike pulls quite well up to 6k but wont rev beyond that, it just farts and spluters and wont go any more no matter how hard you nail it
the red light on the clock seems to start showing its face now
anymore ideas ?

the red light coming on means the battery is not charging
which could be why it won't rev above 6?

i have tried it with different carbs and it was no good
RB dropped by last sunday and i am going to try some v rated plugs ,he has had early h1 before that would not run with v plugs
also gonna wip the heads off and chec the deck heights of the pistons and try another set of heads

Have you looked to see if any 'tuning' work has been performed on the internals?
