I was wondering if it was bad to run 110 octane fuel in a relatively stock blaster? All the mods that I have is Delta Reeds, a Trinity Pipe, and airbox mod. I also took off the oil injection and pre-mix now. Are these enough mods to be running 110 octane??
Thanks

110 is way overkill, all you are doing is spending more money at the pump. 104 would even be a little much. Stick with 93, which is premium octane at most stations. It will give you all the knock protection you will need, and be a lot lighter on your wallet.

with my mods should i run 104? i run 91 which is premium in cali and i knock and ping at high revs.

 

or should i run it 50-91 50-104?

 

Well if it's still pinging with premium fuel then try adding octane boost to your tank, if that dont work try av-gas which is 100 octane and still alot cheapter than race fuel.

 

I heard that putting av-fuel in a 4 wheeler is bad. If its not I could get all the av fuel I want because my dad is the manager at an airport here. lol

I ran my old built warrior on av-gas for over a year and no problems. The only difference between av-gas and race gas is that race gas has a little more lead content, thats it.

 

here in so cal they sell race gas at the pump at 76. not sure what octane is but thought about trying it out. anyone from so cal try this or know what the octane is?

 

the race gas they sell at stations here in mich is typically 104 or 110, usually 104 though.
