So, my FIL just did an impulse buy on a '04 Pagsta Choppa. A friend of his had it, got a DUI on it and stopped driving it 2 or 3 years ago. My FIL bought it in a non running, but titled condition for $500. He's a life long gear head and grease monkey, so he had no trouble getting the little scoot scooting again. I drove it this past weekend, and it's actually a pretty fun little bike. It's got both electric and kick start, and starts really easily. The little 97cc engine runs smooth. It's got a two speed auto transmission, which I'd like to know more about. Can anyone tell me what's going on in that tranny? It's not a straight CVT system since you can feel a definite shift. But, it doesn't act like a regular torque converter tranny since it'll shift up to high gear at a constant speed know matter what the throttle is doing. I guess maybe it just lacks a kick down linkage. The reason I ask is that above about 30 MPH, the bike vibrates badly. It feels like the vibration isn't coming from the engine, but rather the drivetrain. Oh, and to complicate things further, the bike is a sort of hybrid. The OP bought the bike new in '04 with a 49cc engine. That engine blew and the dealership said that he could either have a 49cc engine in 4-6 weeks when they could get one shipped in or he could have a 97cc engine now. So, it's a 97cc engine coupled up to a 49cc bike. The other issue it's having is that the bike doesn't charge the battery. I've traced wires and everything looks good up to a little solid state box. I'm assuming it's a combination regulator/rectifier. The wires going to that box are putting out 30VAC at idle, but the battery isn't seeing any increase voltage no matter what RPM the engine is running at. Is there any source for Pagsta electronic parts? Googling the P/N (which I can't seem to find ATM) shows a Peugeot regulator for 22 euros -but nothing stateside. TL : DR version: Anyone have any experience with these bikes? Know where I can find info on the tranny? How about parts? Thanks much.
