Need A Neutral Switch Replacement

Got home yesterday and my 79 KZ650 SR that I've been working on had a huge puddle of oil underneath it. It's coming from the neutral switch.

The switch was tight so I'm guessing the components just went bad. Surprising because it happened overnight but oh well.

But alas, I need a replacement, and I would like a new one (not an old or used one from ebay). Anybody know if there any that would work as a replacement? I remember finding a new one for my KE250 a while back that wasn't listed as the OEM part number.

Anyone know where I can find one for my SR?

sorry

No eBay APP ID and/or Cert ID defined in Kunena configurationLooked up the part number on partzilla and was unavailable but then punched it into ebay and came up with #13151-5002

Is the switch is working ?

Is the oil leaking between the switch body joining the engine casing?

If the switch is ok then have you tried fitting a fibre washer between the casing and the switch metal washer to absorb some initial oil and seal the joint

Try to find a fibre washer with a bit of thickness, about 1 mm (3/64") or if you can only find thinner ones try a couple or more together, and check the switch still registers neutral ok. If not use a thinner washer or remove one or more if using multiples.

I cannot remember the internal diameter of the washer needed for the threaded area of the switch off the top of my head but I can find out if needed unless someone else has that info to hand?
A good hardware store, plumbers merchant, car parts store, or Amazon may help with the washer you need.

Or consider using a copper washer
