Typical DR350-clutch-problem: The bike creeps forward with 1st gear engaged. It's difficult to shift gears or get into neutral at the traffic-light:
* 1st make shure your clutch cable is adjusted correctly (2-3mm play)
* the thrust-washers (Pos 2) tend to wear out at the sleeve which holds the basket on the gear-shaft. If this happens, the basket and hub can get into contact.
* replace the thrust washers or turn them to the other side and put an additional thin washer 0.2-0.5mm in to clear the two baskets. (I got some of the thin washers in my cellar).
* Beware: The washers are hardened to 480HV.
* My bike had this disease right out of the factory. The dealer (Motothek) was not able to find the Problem within the warranty of 12 month :-((
* check clutch-basket for grooves which can hold the plates in axial position and file away the grooves until you get a plain surface.
