Hey guys. I've had a minor but annoying mis develop. Absolutely fine from cold, once hot at low speed under light throttle it will be jerky momentarily then clear. Also at no throttle when idling it will mis intermittently and can be quite jerky when moving from a standstill. At higher throttle no problem. Bike is stock. Your thoughts please...
 
Could be a MAP sensor or ignition related issue e.g. spade connectors on coil inputs aren't tight, HT lead has developed tracking.
was there any work or anything done to the bike recently?

No work done. Has just started out of the blue. If I am going up a hill about 30mph in say 4th and gradually roll throttle on it will mis momentarily then clear.

I'd add in the TPS as a posibility. The spade connectors and quick easy to check and may be the fix.
