I am looking at buying a 95 banshee. I am new to them but not to 2 strokes. The one I am looking at seems to have very little compression and is hard to start. when you do get it started it only runs on one cylinder and back fires alot. To me that seems like a new topend would probably take care of it. I was just wondering if there are some common problems I should know about before I dive into this head first. I can get this bike pretty cheap, and if it is just a topend I will come out good. Just looking for any advice anyone would be willing to offer.
