Learned quite a bit more about this little pile since I bought it. I know a lot of you are into dirt bikes/quads, and this scooter uses the same engine and driveline as the very popular Yamaha PW50 (PeeWee 50). Also the old YT60 3 wheeler uses the same case design and an additional 10cc's can be had just by swapping the piston, jug and head.

I got the piston free from the cylinder, and I think I'm just going to put rings in it. It was stuck, but not scored and the skirt looks fine. I haven't cleaned the jug up yet, but if I told you it had a stuck cylinder in it, you'd be hard pressed to see where. The fuel petcock on my tank was shut when I bought the bike, so the carb is amazingly clean, I don't think I'll even tear it down, 'prolly just blow it out with some air and carb cleaner and see what I get...
Hoping to tinker a bit tomorrow on this, but I've got a mixture control solenoid to install on the Olds, a crank pulley to install on the Saab, and a huge pile of stuff that is my Luv project...
