Question about 2005 Honda CRF 450 R
Crf honda's run titanium valves which wear out very quickly if valve clearances not checked very regularly. what happens is the valve wears on its sealing face and clearances close up and then valve rides and looses compression,much like a leaking tap. bike will make more compression and valves will try to seal when warm. i probably rebuild one of these bikes a week with this problem. get it to your dealer and have clearances done. you can get stainless steel valve conversion kits which are much cheaper than honda titanium valves.
