·My 99 M900 has started breaking up when it's revved regardless of whether or not there's a load on it. I've been starting it up during the winter to let it run and notice that it will breakup and pop through the exhaust, and occasionally through the intake as well. Nothing has been done to it, other than the dealer replacing a seal behind the clutch basket. It's only after it was there that I noticed this. It also floods easily and is running rich by the looks of the plugs. WhenI bought the bike it had a termi exhaust on it, jet kit, etc. It ran fine during the summer, but it's not looking like it will this spring. Hopefully someone has experienced this and can give me a good clue as to where I should start. I'm thinking it's jetting, but it should become more lean with the cold air... PLugs show no sign of being lean though
