Hi all,
I bought a decent looking 250R a few weeks ago. When I got it, it wasn't running, low compression. The guy I bought it from was running the Dunes and it just slowed down and shut off. I took it home and pulled the top end. Rings were welded to the piston and there was some wear. I took it to the shop and they bored .20 over and I got a new wisco piston and rings. I took it home and put it back together, but still low compression, about 60psi after 5 kicks. I would get a pretty strong pop through the exaust, enough to blow papers off of my bench 6 feet away. I took it apart again, checked the rod, no up and down play, and very minimal side to side. I did notice the top gasket was wet all the way through and the bottom was slightly too. My reeds looked fine and sealed. the carb has been taken apart and cleaned. I do not know a ton about 2 strokes, so I am appreciative for any knowledge lent. The new piston doesn't seem to have any play, but I am used to the rings sticking out from the piston more than they do, they look almost flush. I torqued the heads down to 22lbs, maybe I should have went more?
