Motor cuts-out on occasion.

My 750 runs fine, except on occasion it cuts-out and stops running. It's like the kill switch activates, and all stop. I can pull over and restart..no problem. I'll ride 50 or so miles and no problem..then another day..20 or so miles, and it does it again. Any help please. Thanks

Spray some lube into the plunger on your side stand switch, sometimes they will stick and cause the engine to stop.

I had this problem last fall...as it gets ready to or does die...before the bike stops moving...try turning off/on the ignition key switch...if it starts right back up and takes off...your ignition switch is a little loose.

So I've had the same problem on occasion. I've also noticed that sometimes I have to turn the key to the left AND the right of "run" before the starter will engage. Where am I looking for a loose ignition wire?
A little off subject, but is there a kill switch for if you turn the front wheel too far? I was warming up the bike today and trying to turn it around in a tight spot and if I turned the bars all the way it would kill the motor. Is there a kill switch or is this maybe the ignition as well?

Thanks!

No kill switch at the handlebar locks.

The problem is in the area of the wire harness as it curves around the head tube to the ignition switch. It's not uncommon.

I had the same problem when turning hard right. Ended up being the wires coming out of the switch were rubbed through but mine also was popping fuses for the lights.

Are they the wires coming out of the "kill switch" that were rubbing, and if yes, were exactly were they making contact?
