LawDog Posted April 13, 2012 Report Share Posted April 13, 2012 Finally did my first compression test on my shee i just got and my right side was 185 and the left was 167. dont know what the internals of the moto are (like dome size or port job or cylinder size). am i in trouble and i take it i need to run 110 fuel instead of 93. i ride at sea level +or-1000 ft. and what fuel to oil ratio should i be running. any advise would be helpfull thanks Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted April 13, 2012 Report Share Posted April 13, 2012 whever the motor was broke in on is the safest bet......but 32:1 is usually the go to mix. Also your gonna need some 103-110 for that one.......if not your gonna spend a whole lot more money real quick.... Quote Link to comment Share on other sites More sharing options...
bikerjon Posted April 13, 2012 Report Share Posted April 13, 2012 with that much variation between cylinders, you might wanna freshen up the top end. Quote Link to comment Share on other sites More sharing options...
Josh Z Posted April 13, 2012 Report Share Posted April 13, 2012 yep... 18 psi diff is alot... pull it apart and see if a hone and a new set of rings will help it... and yes with anything over about 155 you want race fuel or at least AV fuel.

RiDeTRIKES250R Posted April 14, 2012 Report Share Posted April 14, 2012 normally 3-5% difference is acceptable... thats way over 10%... i would take a peak. Quote Link to comment Share on other sites More sharing options...
