Whats up. I am trying to help my friend with his 800. I have told him that his stock compression should be about 140-150 psi. Can some1 tell me if this is correct. If you are guessing please dont respond. If you know 100% for sure I would like to here your answer. He is at Sea level. Thanks again.

HEHE

120-125. Actually we both are trying to settle a friendly wager... NJ thinks its 140-145 and I think its 120-125. Stock 800R numbers.

Help us out.

ANY1?? Compression? Arent the GP800 & GP800r's equipped with the same everything, just different hulls and jet pumps? There has to be some1 on here that knows the answer to this.
There is a $100 riding on this
