what octane should I use

[Sidsol]

32cc domes
Wiseco 84mm pistons
Mikuni 44's
Speed Worx dry pipe
Crank is lightned and trued/balanced
TBM charging flywheel


was wondering what octane level I should be using? I went 35cc to 32 cc.

What is your compression?

32cc on an 84mm bore + Drypipe - sounds like you're solidly in race gas territory.
I run 34cc domes with a more forgiving ignition and pipe, and run 96 octane.

Around 200 -210 i forgot what he told me, yeah its a retired Race Ski. Also has the Advent ignition w/ external remote switch, so I can adjust the curve.

I was thinking no less than a 100 octane
