    Couparral 2-stroke

    I recently picked up this little Couparral 2-stroke engine. The guy I got it from said it came off from a small snowmobile he had when he was a kid. Anybody have any knowledge on this type of engine? I'm thinking it could possibly work on a minibike.

    Fitting is the crankcase pulse for a Mikuni fuel pump. My engine lacks a carb or pump. I want both.

    Hi there everybody, I picked up this bike Monday evening. It is actually in really good shape, and hasn't been molested. The plan is to tear it down, polish everything, get the motor running, and leave the seat and paint on the frame and the tank original. Sent from my iPhone using...
