OK, so I disconnect the TPS and it seems to be a lot better.. no stalling at tickover and no misfire on acceleration.
Took bike for a ride and got it really hot.. misfire came back so it wasnt the TPS.
Went to dyno man, issue was RH side was running RICH then LEAN then RICH etc etc at tickover.. WE WAS STUMPED
No idea why but I tried clipping the AIR VALVE pipe closed and the RH side went RICH and stayed stable.. fault identified!!
Took the Air Shutoof valve apart.. stretched the spring a bit and put it back, fault then moved to the LH side.. at last, we now had a fault we can produce!!
I am going to try and get a new one ASAP and see if it cures the problem.. if not I may just block it off completly..
At least now I have a direction on this fault.. been a few weeks but theres light at the end of the tunnel..
