    There is no replacement for displacement.

    I have said this so many times... What if the 2 stroke Had fuel injection? And you hooked it up to a computer,Like N-1 has for his street bike?

    1) the injectors would clog with the premix

    2) the plugs would still foul

    Don't get me started on the oil ratio debate!!

    A my son's 2001 CR80 has the workshop manual state 20:1.
    I have had many dealer and oil sales people say use this or that, "it's synthetic and can be used up to 80:1".

    Running at 20:1 it doesn't foul plugs (unless it is idled a lot), the little end bearing is always perfect come time to change it, the piston is clean (looks new)and it has never gone BANG like some of the engines of people whom with we ride.

    Yes it does blow some fat when he is giving it heaps, but it is a two stroke.
    Don't go changing oil mixtures without adjusting your jetting or a least check how rich or lean the mixture will be.

    I have never had a two stroke go bang when running manufacturers oil mix ratios, the same can't be said for other who have played.

    The fouling you had might not be caused by the oil but things like - too rich a mixture, dirty aircleaner, too much slow speed (can happen on some trails) and too much idling.

    Opps - told you not to get me going.

    i read an article or something about India and some asian countries that 95 percent of their motorbikes are 2 stroke and this company made a efi for them and it costs like $400 and it reduces emissions better fuel economy and more power so i doubt that the premix would clog the injecters and stuff because would the 2 stroke premix clog carby 2 strokes :lol: :lol:

    and if evinrude can build a efi 2 stroke boat motor well they surely can build one for mx 2 smokes braaAAAAAAAAAAAP!!!!!!!!!!
