Not sure what the problem could be, I bought the bike used. It's an '02 with 2200 or so miles on it when I bought it. I've put on about 2000 or a lil more in the couple months I've owned it, but haven't done anything to the bike.....Just looked at the service records, and it shows he's had the oil changed 3 times in 2000 miles. If it helps any, I'm getting between 53-58 miles per gallon. As for practical jokers, I don't think anyones messed with my bike. Not too much crime or anything around here, only a small 12K people town.Curt said:As I understand, the timing is not adjustable on this bike. But if you think that timing is the problem, the timing chain may have jumped a sprocket. How many miles are on that baby?Go over the basics, too, like fresh gas, new plugs, clean air filter, etc.
Do you have any practical jokers nearby? A potato in the muffler can cause your symptoms.
