Moped Army

doesnt it seem kinda wierd that they make nice ass 80cc jugs for it, but you cant really use em? ive seen a link to a german site(of course i didnt save it or remember where it was) that sold "superclutches"... or maybe those jugs are designed for the 2-3 speed models with stronger clutches....... oh well. i do love my sachs. (it was my first) i do have a parts 5051d partsw motor, so i may just attempt to build one.... whos got the specs.
