118 octane????

i didnt get a chance to buy any race gas this week. i usually run 112 octane. there isnt anywhere close around where i live at to that sells vp, so thats why im not running u4. a friend of mine has a drum of 118 and said that he will bring me a gallon to the track. do i need to tell him not to? i talked to a guy with an 05 r1 and he said that when he ran 112 it filed his plugs. will the 118 file mine? i dont want to do that because it looks like a pain in the arse to change the plugs on my 10. i have a full muzzy and a power commander with stock filter if that helps..

Fuel

What kind of compression are you running. If it is stock 118 octane is a waste. VP fuel has a chart that tells you what octane you should run via compression ratio. If the guy on RC51 was fouling plugs maybe he had it to rich. 112 should be fine for your application.

112 or 114 at the most. Wasting money past that. You could make your own oxygenated fuel. Have to be careful or engine go BOOM!

what are you guys doing to need that kind of octane? my understanding is the higher the octane the less power it'll make unless the engine can compress it?

I agree. I ran 118 in a pro stock race car. Can you say MAJOR COMPRESSION!

I run U4 in mine which is 92 octane, but when not racing I run 93 octane pump gas.

u4 or mr9

if you bike is stock as far as no after market pistons then you can run 93 or u4 but some guy don't understand that just because the rating is high does not mean that the bike will run better
