Known problems, poor fitting air box lid and intake boots that leak at the head. Id do a compression test before making a decision. No matter how clean you keep a machine, those can sneak by anyone. If that checks out good and you like it, i would go for it. You'll probably need wheel bearings and a-arm bushings now or in the near future. But that is to be expected with that many miles. Seen posts on here with 20000 plus miles on there machines. Pics are mandatory if you buy the machine. Welcome to the club!
