Re: opti-2 for break in
i broke mine it at 70:1. ran that till i used up my 2 gallon can, and then went 100:1.
i honestly don't think it matters. my next bike i'll dump 100:1 in it, just so i don't have to mix up a different batch.
there's enough people around here that started right out at 100:1, so i think it's all good.
by the way, my bike had absolutely no break in period. it went just as fast the first day as it does now. and it's fasssst.
