No Roy, I haven't because I don't own a 50cc. I wish I did, they sound fun. That sure looks like a quality item though. The price seems right for a high quality crankshaft. I bet you'll be the adventurous guy as usual though and get one.  Rich

I,m going to get one. I plan on a 50mm bbk big bore head. I'm looking for an old non running engine and will do a complete rebuild with better bearings. I thought about a new engine, But the cost of the engine plus the crank, bbk, bearings,seals, and gaskets will double the price. Plus if I build it I know what goes in it. ;D

Ok, I have not been able to find a suitable used donor engine for this project. So I have decided to buy a new engine and rebuild my current one. Any suggestion on where to buy?

Sprocket, yes I finally got the E.F.I. working and it runs great. Putting a 250 in it would be fun, but so is tweaking out a 50.
