Max psi on pump gas?
I'm sure this has been address many time, but came up blank on search. How high can I go and stay safe on 93 octane. We're talking about two stroke Yamahas in general.

It depends on the motor. In general, I beleive all of the two cylinder motors are about 185 PSI max, and the tripples are about 165 PSI max.

Powervalve motors can handle more compression than non-pv motors. With all the ethanol fuels now days, Id be more concerned with adding more fuel, even on stock motors
