Ok I got my bike used with about 600 miles showing on the Odmer. So I start going over it after 3 rides and find some pretty shocking stuff. Well, while its apart and clean, Ill check the valves. I start taking the motor mount bolts off and the last one, the allen head strips out :think . So I figure Ill drill it out and keep going. But Im all upset and its getting late and I want to ride the next day, so I say forget it and put it all back together. My question is, Have any of you boys (or girls) that beat the snot out of these bikes had to acutally adjust the valves on em? If so how oftern? And why would you have to remove the radiators to do it like the book says?
