Question fellas. What gas should i use for my yz 450f . I have been using Sunoco 93. I was thinking about some vp fuel. Will the different fuel make a difference in power on a stock yz 450 with a fmf 4.1 pipe?
I believe the manual calls for 95 octane fuel. This should be your minimum.
Cheapest would be 100LL Av gas.
Next would be 25/75 50/50 75/25. Recreation (no ethanol) fuel cut with VP110

Then rec fuel 25/75 / 50/50 75/25 with VP T4

It all depends what the octane of the Rec. fuel is to start with. It is 90 around here.
Next is VP T4 straight up, no ice.

I would use the straight T4 in a stock 4-stroke, especially in a 450.
Maybe its ETBE...ether way, I will know for sure soon.
