Can you strip the kill switch down?

[SteveW]

Got a very slightly intermittent kill switch on the 550, when the bike is running its fine.

If you turn the bike off with the kill switch, put it back to on, the bike will sometimes not fire.
Moving the switch a few times through the positions and then back to on, it fires up.

Think it just needs a clean, but wasn't sure if it can be stripped down?

The switch can be fully stripped  I have done loads of them .

There's a very small E clip holding the plastic knob on to  the top half of the switch.   It's best to disassemble it on the table to avoid parts disappearing.

Thanks guys

Is the movement of the switch positive. Have you tried switch cleaner, some may get to the contacts. I had an earlier 500/750 type that was intermittent and dismantled it. But some gorilla had turned the switch too far and the metal contact and the location of the detent ball were pretty mashed. Managed to make it a bit better but not perfect. It was the P L H type and sold it. Make sure you have a very good fitting screwdriver for the little screws on the wiring guides etc. and take it easy, they can shear.

The e-clip is easy to remove but a bit of a pain to replace with pliers, if you have three hands it helps! You can buy specific e-clip pliers on ebay. Take lots of photos before you strip the switch, there are a lot of very small parts and the internal wiring routes can be easily forgotten.

The switch feels perfect when you operate it.

I might try some contact cleaner in it first before I resort to stripping it down.

Be careful,  aggressive switch cleaner can break 40 year old plastic.  Best strip it down and do the job properly, polishing and greasing the contacts and checking the soldered connections.  As mentioned,  take photos.

I'd use something like this inside when it's been cleaned;

As well as being highly water resistant it'll not degrade any plastics and should help preserve the components.
