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..
