Parked bike yesterday, this morning... No spark.

What coils are you running? are they 3 Ohm? Do you still have the old glass fuses in the bike?
You can still use a jumper wire to the red/white wire, and the bike should start up. If not, it's probably something to do with the TCU.

for all I know it could even be the coils...they are those problematic ones that people were running for a while before it was figured out they were junk...

the coils where the connectors would just pop out of em

Then just pull all 4 plugs, lay them on the head with the coils and turn it over looking for spark. Quick and positive test. Just be SURE the metal part of the plug on in contact with the metal of the head.

Ray's last statement of his last thread is most important.......no ground for spark-plug, TCI gets very unhappy and may not work again.
