I don't know the bike very well yet, but after all you checked, sounds like you're looking at a hi voltage problem, and you know what that means ! Yes, it starts w/ a "c"   Sad

low battery?  Try a push start with starter assisting.

What is the actual voltage, unloaded and then during cranking?

Actual voltage with it cranking was 11.4v constant.  Battery was fully charged, checked that with a multimeter.  Also threw it on the charger just in case.  Not a battery issue.

Check V on the coil.

According to my Clymer's manual, resistance of the primary side of the coil should be from 1 to 7 ohms. Resistance of the secondary side should be 10,000 to 25,000 ohms. "If the coil does not meet (or come close to) either of these specifications, the coil must be replaced." Measurement of the secondary side is made from the spark plug wire to either of the primary terminals. Clymer's also says the coil must be warm (minimum 68 degrees F.) for an accurate measurement.

I see your original plug sparked OK on another bike but I would replace it anyway.

well on the secondary side I get an OL on the multimeter.  Seems to me I have a bad secondary coil then?  Means a new coil is in order then, no?

You get the same reading as if the Ohm meter leads were just laying on a table? If so, then its Open, & yes, youve found the problem,,
