I just bought my banshee from a friend, and it doesnt run. I have no spark but has had a new cdi, stator, and coil installed recently and it ran with those installed. He said there wa s a pop from the right cylinder and that cylinder would not run. It would take a shit load of kicks to start it and constantly working the throttle to keep it running. I checked compression and it would only get up to about 85 and than it would start to bleed off and the guage would drop after i stopped kicking it. I deassembled the top end it all appears to be okay. The top of the piston is just black from carbon, the skirt, cylinder wall, and bottom end all look okay. Could it just have been the head gasket bleeding of cylinder pressure? Is there anyway of testing the cdi, ignition coil, and stator indepently to see where the failure is? Is the choke tube rubber or plastic?
