Ratshee350 Posted October 19, 2010 Report Posted October 19, 2010 Hey guys, I ran a comp test on my shee the other day just for giggles. I came up with 110psi in the left and 105 in the right. Now i have a cool head on it but i just got the quad a few wks ago and i havent pullled the head to check what domes are in it yet. Would anybody have an idea just by the numbers i gave. Also what is the smallest dome i can run pump gas with. Around here i can get Sunoco 93 out of the pump. THanks Quote
Pasi S. Posted October 19, 2010 Report Posted October 19, 2010 ...just want to say this. I had exactly same numbers in my -06 low hour cylinders. After new pistons, bore & hone I did the compression check and it was only few PSI´s higher! Guess what, I had a leaking tester!! LOL! After knowing that I did it with a better tester and it was good but not as high as it should be with my milled head... Hmmmm after I looked around the forum I did a squish test... guess what - my basegasket was too thick and my squish was huge! Now I know - double check everything! -Pasi S. Quote

I want to say 160-170 is where you should be running race gas, but I could be wrong. Quote
Ratshee350 Posted October 20, 2010 Author Report Posted October 20, 2010 Thanks for the input guys. I thought it seemed low also. I found that stock is about 125. So this weekend im gonna check my guage and also pull the head off and see what domes i have. I really dont want to rebuild this thing till after the winter. I mean its running awesome right now.
