There is no spark at the plugs. The bike is getting voltage to the ignition coils and the coils test out OK. THe pickup coil tests fine. The battery is charged and the charging system was working ok. The is voltage acros the starter solenoid.
If none of the 4 plugs is sparking, then it's tougher to nail down. If two were sparking, you could swap things around to identify the bad part.
Well, start by making sure there is voltage and ground on the ignitor by measuring the voltage to the positive wire when the bike is on, and measuring the resistance on the ignitor's ground wire relative to the battery's ground when the bike is off.
That is,
test one: Voltmeter's red wire to ignitor's positive wire. Voltmeter's black wire to battery ground. Turn bike on. Read meter (DC voltage).
test two: Bike is off. Ohmeter's red wire to ignitor's ground wire. Ohmeter's black wire to battery's ground. Read meter (ohms).
