Fuels (and GSXR1000's...)

[JP]

Any fuel with a higher than normal density will alter the height at which the carb float sits. A denser fuel will cause the float to sit higher giving a leaner mixture (ask the motocross boys about Optimax and detonation).
The GSX750F is not as critical to proper air/fuel ratio as say the competition two strokes, but the same applies to the float height The bike will run higher float height with Optimax. Will the higher density compensate the higher air/fuel ratio? Competition experience would suggest not. <i></i>
