Default Re: Suddenly running better

hmmm, interesting. I've read in several places /suppliers, that 91 octane was important, I wonder why? Perhaps useful for breakin since it "burns slower" to prevent pre-ignition and reduce likelihood of damage? But then again, aren't 2-strokes lower in compression to begin with, reducing likelihood of pre-ignition? 87 it is!!!!
