I have a 94 Banshee and i was riding it the other week when it just shut off like i hit the kill switch. I took it home put new plugs in it and i found out i didnt have spark. I clenaed all my connections and put a new coil on it and it will only spark 1 or 2 kicks of about 20. And sometimes i will get just a faint spark. i dont know what to look for next. can anyone help?
