Valve specs for 02 CRF 450

[Erick82]

My friend recently purchased a 02 CRF 450, without a manual and is looking for the clearance/ valve spec info. I have read the other posts and did a search but couldn't find valve specs. Also, riding hours between checking.

Thanks

Intake .006 + - .001
Exhaust .011 + - .001
Decompressor arm. (Right exhaust valve) .014

Checking them every 6th ride should be good. Depending on how many miles you put on during your rides and how hard you ride.

If you notice any indication of the bike being hard to start. Check the clearance.

The cam/valve arrangement in this motor is a little different. It may be in your friends best interest to purchase a manual.

Just my $ .02

Thank you very much. I told him he needs to get a manual.
