    got this bike not a while back and sets off smooth and when I get to about 30mph then stop at traffic lights etc sets off very slows and takes quite a while to reach 20mph but when hit 20mph it flies off again does anyone know what could be wrong with it

    Too much fuel, too much air, rollers sticking, clutch sticking..................
    Have you got the standard air box or not?
    Has it been tuned at all?
    How long has it been like this?

    More details please of the set-up you have

    I haven't had it for a while but I bought it off eBay and the man said that it has a 70cc kit on it but that's about all the knowledge I have on it

    eeee' your a lad you scuba:D

    Lewis, take the variator off and see if any of the rollers have got big flats on them. You might have one or two that are sticking on the slides and not returning down to the bottom when you stop.
    This gives the effect that you are taking off in high gear and the bike won't get going until it reaches a certain speed then goes like the clappers.
