    i have a peugeot speedfight 2 50cc. when im riding it hits 20mph dies a little then carrys on accerlerating to top speed. but as soon as i hit any hill it will either climb it nice or the engine will die but carry on riding just at a slower speed.

    could this be the clutch or rollers?
    any help would be lovely :)

    this used to happen to my aerox, i could hit a hill flat out and i would just watch the speedo go right down to 15-20mph, used to piss me right off, i was running everything standard with a gianelli exhaust, i changed the exhaust to a pm360 and put in the rollers and clutch springs that came with that exhaust put and airfilter on and upjetted it and for some reason it solved the problem, so i was baffled to what the actual problem was, hope u get it sorted mate :thumbsup:

    hav you got a sports exhaust? if so did this only start to happen efter the exhaust was fitted?
    if so, it could be that you need to change your rollers, as you should change rollers, slightly up-jet and chang your clutch springs when you switch to a sports exhaust, also check your variator for wear, these should only cause that problem if you have recently changed from a standard exhaust to a sports exhaust..
