1973 750 Commando. Pazon Sure-Fire electronic ignition since 2014. A week ago it was running fine, starting with one kick. Then two blocks from home, it started missing and backfiring. Now it won't start or even fire at all.
Took the trigger plate off to inspect and no visible problem. I did NOT remove or loosen the rotor with the two magnets. Then did Pazon's trouble shooting of the trigger plate by jumping the two wires to the trigger plate, and it sparked every time. Checked the spark at plugs with the kick start (no electric start in 1973) and both were sparking - but I have no way of knowing if they're sparking at the right time.
When I re-installed the trigger plate, I followed Pazon instructions (as I've done several times over the years) 1) rotate engine to 31 degrees BTDC, 2) install the trigger plate so one of the magnets in rotor is under the hole in the trigger plate (for anti-clockwise rotation). The post bolts were in the center of their adjustment holes.
The way I understand it, it's a "wasted spark" system that fires every two revolutions - both plugs fire at the same time, one is firing near the top of the compression stroke and the other near the top of the exhaust stroke. So as long as the tiing mark is lined up when you set the rotor in place so one magnet is under the hole in the trigger plate, it should be fine. It doesn't matter which magnet is under the hole or which cylinder is approaching the top of the compression stroke.
I've tried to contact Pazon via their email address, the contact form on their website and by phone. No response from email or contact form message. Calls do not connect to their phone (message I get is "cannot connect"). I called a motorcycle shop in the same town and the call went right through.
Sooooo, 1) does anyone know if Pazon is still in business? Their website is still up and selling stuff, and
2) any suggestions for why it won't fire at all now, even though there's spark at the plugs when I kick it over. BTW, there's fuel int he float bowl (Mikuni).
Any thoughts much appreciated.
