I have a 1999 cr250. I just had motor work done and now my compression just seems way to high. I am going to do a compression test on it soon to find out. The cylinder was ported cases matched, new reeds, oem piston and rings. I wanted to raise the compression a little so I had ten thousands taking off the head. Is ten thousands a reasonable amount to take off?
what is stock compression?
what would be to high?
