You know whats weird though, a friend of mine just got the new 03 R6 and I could have sworn it says 91 octane on it?:confused1fastchick said:
Doc said:This has been debated before. A lot of it depends on your ignition. If your ignition is advanced, higher octane would be the way to go. If you are running stock and it runs just fine on 87, then go 87.
I think the better question is what brand of fuel you're putting in your bike. I only go w/ BP/Amoco. If I can't find that, then it's Mobil or Shell. However, I've only put Amoco in it since I bought it new...no joke.
