Ok, I have a '03 Yamaha YZ450F. In the manual it says to run the bike at 95+ octane, but all we have around here is 92 octane. Should I add octane booster to it? How about run stright 92 in the bike, would that be bad for it? And if not, is there any place to specificly buy 95+ octane in southern minnesota. Thanks, Travis.
