RE: Re: Fuel rating.
Avgas is 100LL, it has a couple advantages like always having the same octane level and also having a very long shelf life.
The problem is that it requires different timing and is also designed for high compression ratio engines in order to get the max out of it.
It can give you a boost, or not. It will make your bike smell bizarre and also tint your exhaust bit blue. Try and see.
