The wording in the manual is a bit unclear, so what do I do with the Engine Stop switch?

Do you always keep it in the run position, or do you switch it to "Off" after you've turned the ignition off? I know that it has to be in the "on" position before you turn the ignition key, but does that mean that it should stay in the on position always? Just want to make sure that I'm not messing with the electrical system.

Thanks,

Old E

Also, I finally got my bike: a very nice 2010 Black Street Triple!

The stop switch is there so you can kill the engine in an emergency-that is why it is big and red and accessible on the right switch gear. It plays no part in ordinary riding and people have reported running issues when they have used it instead of the ignition key. My best guess as to why is that when you switch off normally you get the characteristic noise which is the sound of the shut down routine where all the sensors and solenoids are reset ready for the next start up routine. The kill switch just stops everything.

The kill switch is for dire emergencies only. I have never had to use it in 40 years of riding (thankfully!). The ignition key is for switching the engine on and off, not the kill switch. Simple!

It's in the same circut as ignition so shuts engine down as normal but can leave lights on so better to use ignition switch.
Urban myth that kill switch is harmful to engine settings.

I don't think it is an urban myth, it is a bit like turning off a PC by pulling the power cord. A decent way of crashing a frozen computer if nothing else works but the re-start can be a bit protracted.
What you say is absolutely fine for old school machinery but the complexity of an ECU controlled electronic fuel injection system which reads a number of electronic sensors and resets itself checking each sensor and comparing actual readings with expected readings and cycling the icv is not meant to be stopped in it's tracks by simply cutting power.
If I'm wrong no doubt someone who understands electronics will be along to explain.

Do not turn the bike off with the kill switch - use the key.

I do turn the switch off AFTER I have turned the bike off using the key. This will slow someone down a little if they get my key or try to jump start the bike as the engine will not fire.

Look at the wiring diagram it is in the same circuit as the ignition, however believe what you want.

I've not tried it so does it do the "fax machine" noise when you use it to stop the engine? That would tell whether it initiates the shut down/reset.

I have the Triumph service manual and wiring diagram in front of me.

The "kill switch" cuts power to the fuel pump relay, leaving all other circuits and sensors energized to deal with basically a stalled engine.

The ignition switch circuit is much more involved, interfacing with the ECU, ignition, fuel, and sensor circuits.

The kill switch cuts power to the engine as well.
