    ok in the mornings this is what happens, the rpm's stick until all throttled out. After that it won't do it until the next morning. Sounds like an unlimited cdi but its stock.

    yes, thats your piston slapping from one side of the cylinder tot the other... you see, a piston gets warm and swells, this means when cold there is a big clearance between the cylinder and the piston that the rings just dont take up. (especially on an ac barrel as they get hotter) you ride like any other 16 year old... a wanker.. there is such a thing as mid throttle you know.. oh and if your gonna make vids get somone else to film you. riding about one handed wiht a camera is hardly intelegent

    I really appreciate the explanation, now I understand. Thanks m8 :good:
    So, I suppose after about 25miles it feels a tad sluggish pulling out of corners because the piston has fully expanded.

    *removes video, embarrassing :p

    Slipping belt? tighter clutch springs?
    It's got Malossi Variator with the big white spring, stock clutch.
    I'll order a kevlar belt as this stock one has done 20,000km !
