    Normal Compression

    Did a comp test on my 800... got 118 in one cyl and 119 in the other. I hear 120-125 is normal. Am I good???

    Every guage reads different, they are both very close so you're good.

    I think you should have closer to 150psi with a stock head.

    I've heard that stock compression on a GP1200R is around 125. Yours sounds fine.

    The 66E is 120/cylinder. If you are reading those numbers you are good to go.

    From reading the first sentence I gather this is a 800cc engine ?
