ET: Engine (Twin) Cutting Out

[nigsey]

I think (hope) I may have found the culprit, a problem with the Miller cut out switch on the handlebars. I disconnected it and it started and ran ok on a short ride. A longer test ride will tell but can’t do that until I return from holiday.

My kill button can jam in the shorted position, so I try to remember to keep an eye on it.

My Rapide came with the kill button on the handlebar. I disconnected it and just use the decompressor to shut down. As an off note, just before shutting down, a couple blocks from where I'm going I also turn off the fuel petcock.

All my mags with kill buttons have nice solid SPST switches tucked away. Too many kill button failures. Plus I don't like stopping an engine with the decomp. If it's idling at several hundred or 1000 rpm or more that's a big bunch of hits those poor little hardened pins take, in my opinion giving them a lot more reason to come loose and have a party with your timing gears!

I tend to agree, I’m not keen on using the decomp either. Hopefully my kill switch fix has worked but if it hasn’t at least I’ll know where to look.

Not a problem with a decomp in the head

I have a Triumph 750 with 36mm carbs. It has a mag and a kill button, but often to stop it I just let the engine idle and then snap the throttles wide open. That kills the engine right away.

Good thing you have retained the mag kill button for if/when your throttle jams wide open. These things do happen. ....

Well that potential problem has certainly occurred to me, I think I’ll leave it in place then.

No Brakes, Single gear, Throttle stuck open, Bad Crash !.
Also when we were Kids, Me 250 BSA, My friend 200 cc Tiger cub,

I stopped, He Didn't !, But we got away with it,
His slide had come completely out !.
