Ive been running my 1968 triumph 650 with a a Podtronics capacitor (no battery ) with 4 ohm dual output coil and points. From my understanding this will cause a wasted spark system. Bike starts and runs pretty good. A bit on the rich side, especially with lower throttle position

Ive been doing some research but i cant seem to get a good answer. Some say you should not run dual output with points while others say its ok. Im just trying to understand if my setup needs tweaking or it is ok as is. Like larger points gap etc...

There are several different ways of doing this but as long as the timing is correct
on both cylinders it's fine. The wasted spark is fine, most electronic setups operate
that way. With a normal double ended coil you have to modify the points plate but
i assume you are using a harly type twin coil with the split primary winding rather
than just a 2 wire primary.

The coil is one of those generic jap looking coils that have a negative and positive terminal. Ones you would see on a four cylinder Honda or Kawasaki

nick, how would you modify the pointz plate.

and how are double -lead coils wired differently?

I had not seen this done until i moved to aus, then several blokes came
to my brothers shop with this setup. They did it largely because the standard
6 volt coils wre either hard to get or rubbish at that time. Another popular move
is to use a double ended coil as a normal one by just earthing one HT lead.
