svtjames Posted July 14, 2004 Report Share Posted July 14, 2004 (edited) Hey I jusct recently checked my compression and I'm at 181 in both cylinders. I've been running a 93/110 octane mix but I was wondering if its high enough to just run all 110. Edited July 14, 2004 by svtjames Quote Link to comment Share on other sites More sharing options...
MotulMonsta Posted July 15, 2004 Report Share Posted July 15, 2004 It'll run 110..But just remember...Octane rating is the anti-dentonation properties of the fuel. When you run a low grade furl say 89 pump gas in a high compression motor, the heptane will ignite before the piston reaches top dead center and you'll have engine knock or detonation..bad shit. Octane on the other hand slows the combustion of the fuel and prevents it from spontaniusly igniting. So you can run a high octane fuel in a low compression motor..it won't hurt anything but if you ran a low octane fuel in a high compression motor..you might blow it up...If your bike runs fine on pump gas..use pumpgas as it's cheaper...unless you don't care about the cost..then go balls out on high grade race fuel. My shee had about 181 psi of compression and I ran it on pump gas. Quote Link to comment Share on other sites More sharing options...
SICK BOY Posted July 15, 2004 Report Share Posted July 15, 2004 That's the compression I have and I run straight Sunoco 110 leaded race gas. Quote Link to comment Share on other sites More sharing options...
