Check your spark plug and make sure you do not have a carbon ball on the bottom. Make sure that your spark plug wire is not loose were it goes into the coil. Try changing your ignition/kill switch. Typically these are the culprets. As far as rigging goes any complete circuit of wire can block a signal. Example: tail wires all being metal. I will take 1 metal clevis and make it plastic. Any way try the above mentioned on the engine side and I bet you find your problem. And these days PCM always helps!!!!!!!
