2000 yz250 on 91 octane?

Recommended Posts

I used to run my yz250 on 91 octane, but after top/bottom end rebuild I am wondering if I should bump it up a notch, I could drive an hour or so to get 93 octane but would it be enough? Or should i just find some racefuel to mix in with the 91?

It should run fine on the 91. Most 93 octane pump fuels get the bump with ethenol, which doesn't really mix well with some pre-mix oils. Tdub
