Note:
The delivered engine kit consists largely of individual parts! Assembly should generally be carried out by an experienced Simson engine builder with suitable tools. (e.g. engine assembly stand, heat lamp, shift adjustment tool, etc.)
In the first operating hours, the engine should be moved gently and preferably with the fuel mixture 1:33. (We expressly recommend Motul 800 2T Road Racing)
