badbrad Posted March 10, 2009 Report Posted March 10, 2009 Doing a rebuild of my bro's cr125 '02. it hasnt had new rings or anything done to it at all since it was bought. It runs like a piece of total shit as you would imagine. What is a the usual compression around 1300 asl for a 125? I just want to test it before the rebuild to see how bad it is. Also wondering why rocky mountain dont offer sizes up on the pistons for after the bore... anyone? Quote
