    I use the higher octane because the difference in cost is just pocket change. If it burns cleaner and doesn't contain the ethanol.. all the better.

    Shobiz - when you pull that small rod out make sure not to lose the spherical ball behind it. Mine dropped out and had absolutely NO grease on it. So I greased that up too.

    Hey Wicked - where do you find the Valvoline synthetic 2 cycle oil? I'm using the conventional Valvoline oil which works great but I might switch to synthetic after the break in period.

    The higher the octane number, the more compression the fuel can withstand before detonating - that's all it means. Ethanol is often used to raise the octane level of gasoline & the higher the octane rating is the more expensive the fuel is - as ethanol blended fuel phase separates (shelf life 30-60 days) & given that price for "premium", it's very likely that when you spend extra on that "better" fuel you are in actuality getting more ethanol not less & some amount of water mixed in for your troubles.

    "stuck using 87 octane and had to change a top end shortly after doing that"

    Interestingly this may have very little to do with a "clean burn" and more to do with the cleansing properties of ethanol - w/e the case if there's "crap in the gas" it's not the octane rating, it's time to find a different fuel station.

    and thats why i solely use mobil gas...got a local joint only sells 87 for dirt cheap...blew up a lawnmower and a weed eater...and that bgf engine...crap in the gas was exactly the issue...but honestly the cam2 gas does make MY bike go faster...believe it or not...up to you...but thanks for the info on the combustion, and the gas "octane" meaning...can always count on you for valuable info...

    There are no rubber o-rings or anything else in the carbs of the chinese two strokes. Ethanol isn't hurting anything.
