Hello everyone! I'm new to this site and, in fact, pretty new to riding as well. So, I have a problem I hope you can help with. I have a 1981 XS650SH that rode beautifully apart from it's typically lazy charging system. I bit the bullet and installed a new PMA from xs charge. Since I put the new coil and flywheel on, the compression on the engine is really erratic. If I try to kick-start it the lever gets thrust back into my foot. Not fun. It seems to hesitate with the electric ignition as well. Stranger still, the crankshaft continued to try to turn over even after I turned the kill switch and pulled the key! Any advice would be greatly appreciated! Thanks!
