cylinder kit SCHMITT GST-60 CNC reed valve conversion 41mm for Simson S51, KR51/2, SR50

Schmitt GST-60 Limited Edition cylinder kit as a CNC diaphragm conversion, suitable for the Simson M500 engine case.

The exclusive Schmitt GST-60 tuner cylinder is ported by a traditional local company in small series on a 5-axis CNC milling machine and prepared for the Schmitt diaphragm box. 100% symmetrical ports, perfect angles, and reproducible quality throughout. The best—goodbye furniture screws! The flat surface created in the cylinder design plays its trump card here and, thanks to CNC machining, holds the diaphragm box with 2 threaded holes securely and force-fitted in position. We recommend using a usual surface sealant.
