Default R/R fail. Replaced but no spark... help please.

Ride 1... blew a headlight bulb.
Ride 2... friend spots surging number plate bulbs.
Ride 3... a short ride but fine.
Ride 4 (attempt) 2 days later... battery completely dead.

Charged battery all day, still dead.

Symptoms above suggest to me R/R fail. So i replace the R/R with a mosfet upgrade unit and the battery with a new motobatt.

The bike now cranks but wont start.

I've checked all relevant wiring and fuses. Getting 13v to HT caps with ignition on. Plugs are getting wet so fuel isn't an issue. I replaced the plugs for new and still no spark. I also swapped the CDI for a known working item, still no spark.

So now I'm thinking pulse generator coil. Thoughts?

Any help would be much appreciated

Excess voltage could have blown just about anything, 13 volts at HT cap may be be blown coil insulation.

Have you tested the Spark Plug caps.They come stock at 5k ohm resistance.Anything above 8k ohm and I replace them.
