I have a vespa grande for sale.bike looks like poop but is mechanically sound.
I would be open to just selling the engine/pipe setup too, but i wont ship it because i get lazy and dont ship on time and people get mad. so no shipping. Pick up in santa cruz.
engine specs: 50cc water cooled polini w/radiator, polini speed cases, simonini cdi, and ninja exhaust. Oh and malossi multivar variator.
its probably better for you to buy the engine. but please take the bike too i guess, i gotta move so i dont have room.
thinkin like 600? engines never siezed, and the head and cylinder were machined flat at NAPA's machine shop, so it will always seal super sweet.
one downside? needs cdi box. Can be found for like 40 bux.
