Will check the fueling, however it seems unlikely as it is fine when accelerating, which would use more fuel then merely cruising. Unlikely it is the float level or anything to do with the carbs as the bike was tuned on a dyno and I asked the tuner whether he checked the float levels and he did. He did mention that he thought it sounded like the crank seal, especially after I told him that sometimes when I accelerated it would hit 11,000rpm and just stop, although a new plug has seemed to fix that. Doubt it's the crank seal either as I just had a new one put in 2,000km ago. Any other ideas? Ignition system?
