For sale, bought his little dirtbike and got it running, but then the crank seized :( Is a cool platform but I don't think I have the motivation to see it through. Kickstart, liquid cooled, 4-speed manual, 50cc. Found on Malaguti Fifty Top/Top Fifty.
Transmission shifted fine and has Ducati cdi ignition. Liquid cooled, cylinder has some scoring, so basically buying a parts motor that definitely needs a crank, piston, rings, and probably a cylinder unless you want to hone/bore and find an oversized piston.
Mazzucelli makes a crank for these, if you want I can help you get ahold of one, there are also a few kits out there.
Anyway, you get the whole engine, and all ignition components. Make an offer if you think you wanna take on the project!
