change of TPS is the next step. Will post results when this has been done.
Keep me posted how you get on.

Blimey! Sounds identical to the problem I now have since fitting FIM UM171 Chip to my (bitsa) 916SPS (8000miles). Almost unrideable in lower rev range (2-4K rpm), splutters, spits and generally runs like a pig - making it impossible to ride smoothly and safely into and out of corners.
I have a JHP Chip for it but that is overfuelling (stinks of fuel) and is a pig to start. Am intending to call MotoRapido as I have a Trackday on Monday!

Bike has had a recent big service and TPS/throttle set up etc etc.

Maybe we can get a "job-lot" discount for finding a cure???

It's Fixed!!

Took my bike to Sigmaperformance and Neil S did some tinkering - needed a new TPS and now it is sorted.

Hurrah!! It's so good to have precise and smooth fuelling!!
