motocrossistheone Posted July 25, 2014 Here is the deal, my crf250 08 has become hard to start I have cleaned out carb and bought new plug. I recently done decompression mod and put new intake valves in and shims and the clearance was put back to 0.05 now I checked it and could fit 0.15 in both easy enough my exhausts can take 0.30 easy enough is that way out??

dirteta Posted July 25, 2014 If it was done properly and now the gap is bigger, something could be failing in the valve train Share this post Link to post Share on other sites
