Bought a rather neglected 101S with a rattle when it runs. I thinks its the CVT or the clutch, not the donk... Can anyone suggest where to start, like what covers to remove to have a looky? I've had a burgman apart before so am not scared of getting dirty and oily. It also seems to rev very high before the clutch (almost) engages. maybe it's just me not used to 2-strokes. Thanks, Jimbo
