I didn't catch the fact that the radiator fan had siezed up and -shocker- the previous owner forgot to mention it. I am sure he knew and it explained his desire to take my offer. At any rate, I took off the gas tank, fairing and radiator and swapped out the fan unit. While I had the bike apart I did a calibration check on the thermostat and it worked fine. I cleaned up the fins and then I also replaced the coolant temp sensor. Even though it worked fine I thought it would be prudent to just replace a 26 yr old sensor for 40 bucks while I had it apart. The cost for labor would be 5 times that at a dealer.
I learned a difficult lesson when I refilled the coolant. I overtorqued the drain plug and stripped the soft brass plug. A new plug only cost a couple bucks but I had to wait till I could get to the dealer for the part.
The good news is that I put it all back together and the new fan started spinning like a top once the temp sensor called for it. Very satisfying but my problems were not over yet.
