has neone had any problems with the gas caps on their 04' 650's? Mine never really did screw on right, didnt seem like the threads matched at all, then when i went riding the other day, i started smelling gas, i looked down and i didnt see the cap anymore, it had splashed all over my leg and the plastic. I walked the trails looking for it but no luck. I went back to my uncles house and grabbbed the cap off his 500, it fit better than my old one, and they are different caps. I just ordered a new one, hope it fits better, but they make u buy the gasket and the cap seperately.
