Hey, guys. Love the site! anyways i'll cut to the question.
I have a 2000 Honda CR125 and last year i did the top end toward the end of the season. I had left the rings too long because there was a fair amount of blowby. The compression was at about 145-155psi. So i did the whole top end with everything stock. All new gaskets, piston, ring, small end bearing, wrist pin and circlips or course. So i break it in easy. Let it idle for a bit in my garage (up to operating temperature. Then took it out to the track. I drove it for 15 minutes each time and let it cool until the cylinder and radiators were cool to the teach. Each 15 minute session the throttle positions when up. First under 1/4 throttle, 1/2 throttle, 3/4 throttle, and then i gave her a good run and worked her hard. Byt now my compression is at like 135psi! When i deglazed the cylinder i used a 400 grit of wet emerycloth if that helps you.
What could be the problem? What can i do?
Thanks a lot for your help!
