Are you sure it’s getting a constant flow of gas? Those vacuum petcocks fail.

Shutting off and not getn fire to coil until you cycle kill switch or ignition. Its carbed and gettn plenty of fuel just cuts fire to coil from ignition. Just like you flipped kill switch

You are describing a failing Bank Angle Sensor. Having to recycle the the switch is the procedure to reset the BAS so the engine will restart presumably due to tip over occurrence.

That and the kill switch is first thing i changed. But i got a used tsm and its doin same thing. I have killed bike by turning tssm and trippin BAS and when it does that the starter wont ingage either till you reset it with main ignition/ power switch. When my bike dies you can crank and crank it but wont fire til you cycle either switch. I suppose i coulda got a bad used tsm doin same thing but my mind tells me differently. Whats the odds

“Whats the odds”
50/50 since used electrics are almost never good unless from a new bike stripped to make a custom.

Its a gamble

Buster do you know if security alarm feed is supposed to have voltage to green wire all time? I know brown wire is derect to fuse as its tied in with brown wire going to tssm. But i wouldnt think green wire would be hot. Brown has normal 12.5-13 volts green has like 10.8 volts
