Actually my first port of call would be to check the bike idle speed by ensuring the the engine has a steady tick over between 1450 - 1500 rpm at shut throttle. Other than that you might require a fuelling fix, by means of altering the Co2 values in your A/F mixture, in which case if after you've checked the idle speed, things won't improve then please send a pm to Kev who will point you in the direction of a few threads that can help you with that issue.

In any case don't despair, lots of helpful people here to lend their support every step of the way.
Cheers
