    hi everybody
    can anybody tell my if a 299 is faster than 499?
    i have two spartamets
    i have change everything between two bikes exhaust, carb, ignition coil, cdi, and 299 is faster even with standard cdi 299 is more powerfull, the 299 climb a hill, the 499 don't even with a diy cdi
    i open the 499, engine and piston, ring, clutch, and a long etc are ok
    the only thing i cant change is the inlet valve cos the 499 comes with decompression valve (this one is checked too)
    sooooo i'm lost

    Just need some help with a Rotary Ladybike carburettor. Pulled it apart to cleam ad the bike had not been used in years and was all full of gunk.
    All good except I have a little round spring that I do not know where it came from. A longer round spring came from under a plastic part with 3 retaining screws. The sgorter one I have no idea.
    Anybody has a drawing of all the parts?
    Thank you.
