250-500cc Lost Spark

was crossing creeks Saturday and finally it just quit and I coasted out of the creek
no spark, checked the wires, unplugged the kill button, nothing

bummer...SEM?

water caused? does the ignition cover leak?

Well it's back to the usual, check for loose wires
Then swap parts over of a known good one.. wich i think you have access too?
Failing that it's multimeter time.
Yank the stator cover off let that air.
New plug check
Coil check
Check the pick up sensor on the stator
Blah blah
That's a bummer man how did you drag the dead dog back?

I've had a kill switch due on me too so I disconnect them first aswell.

i did forget to mention it's a 99 360
with a recently new ignition, at least the mag
