Any successful DIY neutral switch installs on MK2?

I am aware of the "don't try it" conclusions from attempts to install a neutral switch/indicator light on pre-MK3 Commandos. But if someone on this forum has successfully done this, I would really appreciate your advice. It doesn't have to be "original-looking". Thanks very much.

Well I'd think you would start by drilling and thread tapping where the MK 111 model switch exists .

With a NO plunger/roller switch threaded into the hole, is it just a matter of machining a notch in the cam plate that will engage the plunger when in the neutral position?

Yes. But after riding a Norton for a few rides knowing if you are in neutral or not will be second nature.
