Thermoswitch options

[Glamisman]

I am looking for a 1/8 NPT thermoswitch to turn on the oil cooler fan. Internet searches have come up with zip, one of my usual sources has a 1/16 NPT thermoswitch but no 1/8 NPT to 1/16 NPT reducer Anyone out there use a 1/8 NPT thermoswitch or do you run the oil cooler fan all the time?

What sort of threadding do most of the Japanese bikes use? Might be worth a look that direction...

The metric equivilent is 10mm x 1mm pitch, but there are also some 10mm x 1.25mm pitch fittings.

Radiator Fan Harness
And here is one fromhttp://www.watsons-streetworks.com/ ... tches.html

It has an adaptor from 3/8 to 1/2 so maybe you can get an adaprot going the other direction.

This is their pitch:

This is the best "standard" Radiator Fan Harness we could find. Thermostat with 3/8-NPT thread, stainless steel 3/8-to-1/2NPT adaptor, connector, relay, relay socket with wire harness leads, fuse holder, fuse, the necessary hardware for installation and instructions. Turns ON at 195? and OFF at 185?. If you're putting in an electric fan, this kit will make it operate right.
