Good report on the Pazon here. Got a kit from Goffy on the SA that came with a small Emgo twin coil. Never let me down.
The coils (waste spark) however take a big chunk out of the electric supply so that needs to be kept in good order to cope.
I run the bike permanently on a 10w halogen pilot bulb and a led tail/stop light. Battery voltage stays on 12.5 volts that way.
Never measured the exact amount that the ignition system consumes but my estimation/experience is that it must be close to 30 Watts.
Also don’t let the battery voltage drop below 10V or it starts to misfire at low revs and when trying to start then it has a nastier kickback than a Goldstar 500 on full advance.
