I got my Banshee home yesterday and began to check all connections and I got it started in about an hour. The real problem was that one of the cables that go to the ignition lock wasn´t attached to the ignition lock, the connection between the ignition lock itself and the cable was broken off.
That was the first problem, and the previous owner had an aftermarket switch with a tether and he had probably cut the wires to that when the engine lost it's spark. But the thing he didn't think about is that the cables aren't suppose to be connected to each other which he had done. So i fixed these 2 problems and now it runs good, it even had aftermarket pipes, aftermarket air filter and newly changed pistons that has only runned 5-10 hours. The problem now is to get some grip, it's full of snow outside!
