amooseondaloose Posted November 22, 2015 I just pulled on of the cams on my 2005 kx250f because it cut off on me when I was riding last it acts like it isn't building compression and when i took the cam off, the bucket on top of the valve was broken and the valve appears to be broken I haven't pulled the head yet. Just wanted to no if this is a common problem. It also is a nsf head it seams like also wanted to know if that's a stock head. Share this post Link to post Share on other sites
teamgreen8 Posted December 2, 2015 Have you ever shimmed the valves? And how did the piston look on it? Share this post Link to post Share on other sites
