Depends upon the temp...as you are probably aware. I would check the fan relay to see if it is blown then run 12VDC direct to the fan to see if it works. The thermostat is the control device so be sure that it is OK as you say.

How do you know that ?
What about the pressure cap ?
There could be an air bubble in the radiator loop or low coolant level.
Is it safe to assume that you check the actual radiator and not just the overflow bottle ??

On some bikes, the fan seldom comes on at all; on others it runs off and on pretty much all summer.
If the temp light is coming on but the fan is NOT, then it's very likely that you have a fan problem

I have a 1986 Suzuki vs700 I'm working on. Anytime the key is in the on position the fan runs nonstop. Does that mean the thermostat switch is broke? I found these wires like this from previous owner on front left side of bike. What is the solution here? If I'm reading the diagram right the fan shouldn't be running because it isn't grounded via the switch. What am I missing?

Trace the wires that are actually wired to the fan....my guess would be its directly wired to the ignition circuit probably because the fan thermostat relay failed causing it to not run at all. Another issue it may be is the original owner felt the engine was getting too hot and decided to run the fan constantly.

Good luck

Yep, I figured it out when I got home from work....the fan motor is hardwired....im guessing either due to failing switch or previous owner thinking bike was getting too hot.....thanks brother
