- Small sprocket 14 teeth

Attention:
This kit requires its own cylinder + piston + head and carburetor!
The own engine housing and side covers are reused! (Engine number remains the same)

Details 5-speed gearbox:

- Needle-bearing clutch pressure plate (ZT-Tuning)
- Clutch discs A12 with reinforced driver tabs (power absorption up to 20 Nm)

Other significant components:
- Gasket set Kautasit

- Screwed shift drum shaft
- Needle bearing for shift drum

Note:
The supplied crankshaft is designed for an engine capacity of up to 60ccm. Therefore, no larger cylinder + piston should be installed!
Reboring of the housing bore is not required for this engine concept.

- 50ccm, cylinder with 46mm liner
- 60ccm, cylinder with 46mm liner
- 60ccm, cylinder with 46mm liner, bored and ground to 42mm piston size

In any case, the free movement of the kickstarter pinion must always be checked. The 5-speed gearbox with long 1st gear requires a little more space, so the housing must be milled out in this area.
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 handled carefully and preferably with the fuel mixture 1:33. (We expressly recommend Motul 800 2T Road Racing)
