    Have any of you guys use 100LL Aviation fuel before on your high compression performance motors? It's 100 octane rating, I believe, and is leaded gasoline. Just wanted to throw an option out there for you all, some of these fuel are readily available at certain gas stations, I think, mostly near where there is an airport. Not that expensive either, I know some dirt bike riders use it on their motors and have had good results.

    Yeah I've used it off and on over the years and if you have high enough compression (between 10:1 and 12:1) it definitely adds power to your engine. I used to get it at Montgomery field airport for a reasonable price as well.

    Now I'm running VP 110 race fuel and a 15:1 compression ratio in my 215cc race bike........good stuff!
