A grey cast iron cylinder with 75 cc displacement for everyday use.

The cylinder has a bore of 46.5mm, therefore it is necessary to spin on the engine housing (Ø=50.2mm, depth=30mm) to be able to mount the cylinder.
For an optimal power output, both the crankshaft and the engine housing should be machined according to the instructions (see Downloads).
