Radiator Fan
About 2 months ago I put a new radiator the the bike. And it finally got warm enough where the fan would kick on. When it did it started making noise, when I took of the fairing I can see where every blade rubbed against I am guessing it may have been rubbing against the metal cowling that is around the fan. What would case that. can you hook the fan backwards when you connect the plug, so the fan is running backward. Any suggestions welcome, Thanks Mike

If the fan has been out and someone hooked it up in reverse yes it can turn the wrong way, which obviously would not do too much for the cooling of the engine but the plug cannot be reversed accidentally.

When the fan is running hold a sheet of paper at the front of the radiator it should be held there by the wind direction if it blows forward the fan is running in the wrong direction.
The only stupid questions are the one's that are not asked.

Thanks I will have to try that next time it gets hot enough to kick in the fan. You answered my question because I thought I may have plugged in the fan backwards

Running forwards or backwards, the fan should not make any unusual noises.
It may be wise to remove the fan (I know, you just installed it) and bench test it to see where and why it is making noise.
Once solved and if serviceable, reinstall the fan and not worry about it.

Since I read these bikes do have a problem with the thermal switch not working, I installed an indicator light to come on when the fan comes on.
In this way I know at what temperature the fan comes on and goes off. If the temperature gets to that point and the light (and fan) do not turn on, then I can manually turn the fan on with the switch the original owner installed.
Incidentally, the light is wired in parallel with the fan so it will come on when the fan is on. In this way, when the indicator light bulb fails, the cooling circuit will continue to function properly and not cause the circuit to have an ‘open’.

Check the fan out before any damage to the blades, fan frame or engine, can be done.
