Auto decomp not working on 06 CRF250R

Recommended Posts

06 CRF250R. Auto decomp does not work whatsoever. The autodecomp lobe does not contact the exhaust rocker at all, so the valves aren't opening. There is a lot of wiggle room in the lobe though, enough to make it touch the roller on the rocker. What is my issue here? I don't think its the exhaust valves being not shimmed right, they are right at 0.010". Bike runs fine, apart from the fact that I need to bump start it as I can't kick it over fast enough. It also has a Hot Cams Stage 1 cam.

Yeah, I have Hot Cams Stage II cam in mine and the compression release does not work also.  When I have the top cover off and turn it over by hand it appears to work fine opening the exhaust valve as it should.  But, when I button it up and kick it, I am getting full compression.  Next time I service the top end I am going to take the compression release stuff out.  I don't get it either...
