A buddy of mine is looking to buy a 2002 crf450r dirt bike. Does any one know where to look for problems or if that yesr had any significant problems? thanks

The Valves in this motor are really the only weak point, they are a 2 piece titanium that have a tendency to break. Just make sure the valves stay adjusted and that the cam tensioner spring is still very stiff.

Thanks for the info :)
