I just bought a '99 400 with vry little time on it. After buying it, I have read and heard about "problems" with the clutch. If anyone could fill me in on any of these clutch problems, or anything else I should look for, I would greatly appreciate it. I am planning on spending alot of money to make it an enduro/HS bike, so anything I could do to bulletproof it, I want to do now. Also, any tips on gearing for tight woods and rocks would help out. Thanks in advance!
