[Bada$$banshee]

My banshee will not fire every time on one side I'm pretty sure that it's electrical because when I switch the spark plug wires it switches sides it only cuts out when you try to go and it will not hit the powerband what sorbet ever once in a while the side will fire and about rips my arms off it pulls so hard I have tryes putting a new stator cdi coils coil box voltage regulator and gone through almost every part of the wiring harness looking for bad wires I need help fast because I'm trying to go to the dunes soon any help would be very much appreciated
