42mm reed conversion kit for the Morini m01/m02/m03/m04 family of engines. Same design as the big 45mm kit but now 42mm! Fits most cases. Fun reed power without the headache of adapting the 45mm kit.
These come with a reed valve again!
Do note- either the reed OR the cylinder will need to be slightly modified for the reed to fall in place. Nothing you couldn't do with a file but a rotary tool would be easier.
Comes with cylinder, piston, pin/clips, ring, intake, reed valve, and gasket set.
