Compression on a 2006 crf250r

Can anyone tell me how much compression a 2006 crf250r should have? I have looked all over on line and can not fine it anywhere.


I don't know the exact spec but 4 stroke motocrossers typically are in the 50-80psi range. Actual compression is much higher but the auto compression feature messes with your figures. I like to do a leakdown test if there is a concern about the engine.

Here is the page from the service manual
