Remove that kill switch ENTIRELY. My magneto failed 10 minutes after installing my kill switch when my bike had about 300 miles on it for I thought maybe I like an idle that I can shut off.
Never again.
My bike is set to shut off when my throttle is all the way down.
It's perfect for me. I look way cooler when I stop and dismount. I can get my motor to stop at a perfect moment. Not stand there holding down the switch and waiting.
I can also get it to stop when I'm coming down a hill.
And best of all,it's been about 600 miles since my magneto has failed me again.
I do keep a new one in my tool pouch just in case.
But I never liked the idea that your essentially shorting out your magneto every time your pushing that button. I mean that's a pretty obvious strain on that part in my eyes.
Even in lawnmowers when you shut her down you either just throttle down the lever or release that bar that physically applies brakes to your rotating engine.
On cars,it's disconnecting the circuit. Not shorting the circuit.
Maybe if you do away with that whiite wire entirely and get a switch on the blue wire. Then when you turn it off,your just disconnecting the curcit. Not shorting it. I dunno. Maybe that's a better deal if you really like the kill switch idea. I guess it's really a safety thing.
But that magneto is pretty small to be doing what it needs to be doing. I would do whatever it takes to keep that thing from straining.
No kill switch for me.
