Motorcycle Questions? Ask a Mechanic.
Hi and welcome to JustAnswer, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.Initially, have you checked the burn colors of the spark plug tips?
...attempt to start again with the side stand folded up? ...clutch lever pulled in?
And to avoid asking you to do something you've already tried, can you please tell me what / any and all troubleshooting / specific steps you've already attempted other than the above checks on the "...signal generator..."

To my recollection, the ignition coils would have a consistent IGN+12V on 1 of its wires
a pulsating voltage to ground on the other.
Both are DC voltage.
The pulse generator would be producing a pulse also but lower thus it would be AC in a sense.
Is your Haynes manual in electronic form?
The pulse generator would normally produce 500mV to about 1V. And as its name implies in pulses. These pulses trigger the ignition module to drive to ground the other wires of the ignition coil. These high speed switching to ground induces high voltage at the secondary of the ignition coil = spark.
So first, we must establish the presence of these low voltage pulses from the pulse generator.
Can you post back with a picture of the wiring diagram? ...again to serve as common reference.
Bear with me for possible delays, mobile with sluggish Internet if at all.
Appreciate your kind understanding; was mobile.
For some reason, the right half is missing.
Still, locate the black and black/white wires of the engine STOP switch. For test purposes, jump these 2 wires together. Attempt to start again / check for spark.
