I just bought this banshee, The guy told me it had a fresh top end (I heard this before). Its been running pretty strong the last week. I installed a adjustable timing plate and set it at +4 degrees and I went for a little putt on some trails next to my house. I was in 6th gear and had it pinned and all of a sudden it wouldn't take any fuel and was bogging at 1/2-full throttle and eventually died. I pushed it up a pretty big hill and rolled it down and got it started by popping the clutch in gear. Still wouldn't take any throttle but I got it home with 1/4 throttle and choke out (10-15mph). As soon as I got home I pulled the plugs and they were wet of course. I took a quick compression test and The most I got was 80psi After 4 kicks and both cylinders read pretty close to the exact same. Im at 7100ft but Thought it was a pretty low reading and it needs a top end. Anyway I pulled the top end today and I don't know which direction to go the cylinder looks pretty good other then some light scratching but the piston looks pretty bad, rings are thin too. What would you guys do?
