I think my problem lies in the wiring in the headlight...
Ive had all the handle bar electrics off and changed both coils, ive plugged all the wires in the headlight back up (i must have got something wrong) and now the killswitch seems to cut 1 or 2 cylinders but doesnt stop the engine.
All i can think of is that its the wiring that goes to the actual switch in the headlight?
