Misfire when rolling on the throttle.

Another update - Dead happy. Went for a longer run last night and the problem has well and truly gone. It pulls well from low down in the rev range without hesitation and feels like a 600 again rather than a badly set up 350. Looks like I'll be keeping her for a little while longer then, my eyes always start to wander to newer bikes when this kind of thing happens. The MT09 still looks sweet.
