With the new 1ph stator, Tri Spark and Podtronics power box - and an inline switch on the power side - the bike fires up first kick- and runs great! Brid.
Sounds like you got it.

I would stay away from grounding kill switches. Don't know about Tri Spark, but Pazon warns against them. About the only safe way to do it with Pazon is to ground one of the trigger wires, which you don't have with the Tri Spark for twins.
