Adam, I say thank you very much.
mo4/b(3-speed) morini (40mm) 50cc gila reedvalve conversion (very rare) cylinder kit. (new crankshaft seals and a little lok lokie in side and all is aok, vrom vroom soon)
It should work well on the microcar as a back up engine for me and my co-pilot.
I would like to buy a v1 minarelli v1 piston port and a v1L reedvalve.
I see you clone it spec from the factory polini/gila kit. Smart thinking.
