I have noticed when my 200S is in neutral and i give it high revs suddenly a cloud of black smoke will puff out. However ive been riding it up the driveway and looking to see if it happens while the bikes in motion and it doesnt. Why would that be. It doesnt happen when Im just normally riding it. I also have reason to believe my bike is running quite rich. Would that have something to do with it. Its been doing this for quite some time now.
