Leaky neutral switch

[XJkid]

I cannot stop my neutral switch from dripping oil on my exhaust. It is leaking from the screw hole where the wire attaches. There seems to be some kind of annular gasket around it.
I am tired of my bike smelling like a piece of junk and oil covering the underside.

Switch is still available...

Cool! I somehow figured it would be unavailable.
Thanks.

You betcha, there is also a copper washer (banjo bolt washer) that sits underneath, also still available. Your old one will probably be fine or use a brake line washer which is the same size.

Thanks for that! I'm in the same position and just happen to have a few banjo bolt washers around.

Question: can this be taken out and serviced with oil still in the engine or should I wait until oil change time?

Tilt the bike to the right and prop it up while removing the switch. The oil will be away enough.

Don't make the mistake of buying an aftermarket Chinese made switch off of Ebay. Buy an original replacement.

Sure enough the switch itself is leaking on mine and not the washer, I'll be finding out if the Chinese knockoff I got on eBay works later today.

I tried those and they don't fit tight enough and will allow oil to get past the washer. The threads are not cut tight enough to make a good seal. Maybe they have fixed that but I tried two of them with no success. Getting that sensor on and off is a big enough pain to not want to do again and again. Why I suggested not to buy or use them and to get an original. Costs more but generally last for a good while.

I haven't dug into it yet but perhaps a wrap with some Teflon tape will help, thanks for the heads up.

Use a NYLON washer and some thread seal, NOT teflon tape! Yamabond non hardening should do the trick, and not get bits of teflon into the oil system.

I tried all of that and the thing still leaked around the washer. My solution was to chuck those in the trash and I bought brand new ones and that solved the problem. I hope you have better luck then I did. Keep us posted.

An OEM switch is only $25, why risk buggering up the threads in the case with el cheapo?

Because I'm not a rich bas#@d looking to pi@# away his kids inherence. Besides I have other hobbies like housing myself and eating.

Ok, your choice, just saying. A burger and fries is about $25 these days.
