The guy that runs the Magneto Guys is the father of the guy that runs Kingpin Components, who make the other commercially available oil valve with electrical interlock.

We have the magneto version of this valve on the 650ss and I really like it.
It is built well, is the most unobtrusive of the bunch, and there is nothing to fail - it’s a ball bearing riding on a thick metal strip.

On the magneto version, the switch is closed in all positions apart from when the valve is fully open.
So the magneto is earthed until the valve is open.
Because you need the opposite action for electronic ignition or points ignition, their solution is to ship a micro relay with their ‘coil ignition’ version.
The valve itself is identical.
I don’t like this at all:
- when the ignition key is on, but the valve is still shut, the relay is energised, breaking your ignition circuit.
- when the ignition key is he, and the valve is open, the relay is not energised, and your engine ignition circuit operates normally.
Great that when the relay fails, you can ride your bike.
But not great that when the relay fails, you no longer have an ignition interlock.
It’s a tiny relay, and I feel not robust enough for use on our bikes - it feel that it will fail, and you won’t necessarily notice it.
My preference with this valve would be to wire it in to your horn instead.
No extra relays, nothing to fail.
If your oil valve is shut off, and you turn your ignition key, your horn will beep.
I think this is the most reliable way to use this particular valve on a coil ignition bike.
