The 1200s were well known for the thermostatic fan switch to go bad.

It's mounted on the thermostat cover. Discontinued part, but some places still have stock.
Partzilla shows 2 in stock.

some will transfer over to auto applications, honda likes to use some of the same parts in their cars

just have to have some particulars, temp for switch to activate, what it does when it activates (complete the ground or open the circuit), and the diameter of the threaded part and the tpi.(threads per inch)

Thanks for the help guys.I removed right lower fairing and located the thermostatic fan switch, pulled the plug off and cut the wires and twisted them together just to make sure the fan itself was not bad,sure enough the fan came right on when touching the two wires.Cant help to think about installing a basic toggle switch and locating it for manual fan function .bad idea? Thoughts? Thanks again.

When I had my '85, I added a manual switch as a backup since there were a lot of these thermo switches going bad. Just wanted to have a way to turn the fan on just in case.
I wouldn't rely on only using the manual switch though.

I have used a manual switch on a couple bikes and of course it works just fine you just have to remember to turn it on and then again you can wire it to where it runs when the ignition switch is on but that will shorten the life of the fan as it does not need to run above 30 mph ..
