    In '07 I bought a Beta 200 new in the box. From day one it got nothing but VP race fuel, and full synthetic pre-mix at 80:1. More than 350 hours later, that bike had more compression than I have weight. That poor two hundred rode the Ute cup in '09, not to mention almost every weekend of hard riding for practice, and events. When I sold it two years ago, it still had the same top end(I never even took the cylinder head off), and like new performance. I'm no authority on the subject, just telling of my own experience.

    +1 on VP fuel and a good quality oil at 80:1.

    I run VP C9 fuel and Motul 800 on all my bikes.

    Yamalube-R,semi synthetic. Its whats for dinner,Ive always ran it and its always worked. 32 to1 because Im an old school 2 stroke guy. Never had to clean a power valve yet,never any buildup of any kind.
    Ive gone 4 years of abuse on a KTM200 and it still had 160 lbs of compression.

    80 to 1 is a rich mixture,not a lean mixture. The bike is burning the gas to make power,not the oil. less oil = more gas per gallon of mixed fuel. Bike just has to be jetted for whatever is running through it. Bike will run richer on 80 to 1 then it will on 32 to 1.

    I know these are tough things to hear sometimes.

    You sir,need a hobby. The one thing you dont want to do is keep changing what you run in a 2 stroke.
    Its not science,and the 2 stroke gods will be angered if you keep blowing different colors of smoke out of the same engine. This concentrated thinking about the pope and what hes wearing can only lead to no good.

    Nothing special just IPONE Synthesis 2 (half synthetic) with 1 : 75, sometimes less oil somtimes more oil depending to the course. For trial "hiking" with roads and longer downhill parts more oil, for training thight stuff less oil.

    Gasoline depending to the situation, Aral Ultima or Shell V-Power if I have to get it directly from the station otherwise Aspen racing, (because it can be stored really long and I don't have to rejet the carb and the gasoline doesn't smoke).

    I have heard about some old outboards that were plain bearings as well. They need the 16:1 to live. You can tell they have been on the water as the oil sheen keeps the mesquito larvi from breathing, further reducing the mesquito population.

    My chainsaw a Husky 266 XPG uses Aspen gas with Husqvarna two stroke oil 1:50, but now we are ou of topic I believe.

    To the bearing:
    This reminds my to my youth where a guy in the neigbourhood tried to tune up his 50cc moped engine until the
    engine finally - the wiser gives up in situations like this - abandoned.
