    My mk 1 zip sp has about 7000m on the clock. i fitted a pm70 kit to it with other mods as the thread shows. When im at a speed past 40 it sounds as its coming from the variator side make a like wobble kind of noise? its a hard noise to explain and no chance of getting a video/recording of it lol. anyone ever experienced this before?

    could be something as simple as a worn belt, I had a similar noise and that's all it was

    check discs for run out, tyre pressures are OK and wheel bearings dont have any play.
    Does the noise change/increase with revs or speed or both
