ok... older models did not have the tank vent, but they do vent through the cap as far as I understand it.
Couldn't hurt to clean out the cap.
The noise you heard might be the cooling fan. I would start it and let it idle till the fan kicks on (about half way up on the temp gauge) and take a good listen to it. It could be possible that the fan is loose or worn and making a noise (possibly slipping on the shaft). If the fan is defective it would definately explain the spike in temperature.
I still think you may have a fuel delivery issue and possibly the overheating is a byproduct. It could be that your jets are clogged.
What color are your plugs? we need to determine if it is lean or rich.

|sdphill92||I dont believe my bike has the gas tank vent, in that link you sent it says 88 and on mine is an 86. Also I have had the tank off numerous times and the only think connected is the fuel valve and the fuel level gauge wires....|

|sdphill92||Im wondering if that might be the case. I did have over a half tank but I have been noticing a noise coming from the front of the bike, not so much whistling but like a loud humming. I kept thinking it was the fan making a weird noise. Im definatley going to check that out.|

have you looked at your plugs to see if it is running lean?
To me it almost sounds like the start of POOGS. Do you get a whistling from your gas cap by chance? was your tank about half full?
POOGS (Phantom Out Of Gas Syndrome) happens when the venting system in the gas tank is clogged and won't allow air into the tank to displace the fuel being used. around a half tank full it becomes a vacuum and prevents fuel from flowing to the carbs. It starves the engine of fuel and will run lean until it just quits.
The overheating may be a symptom and not the cause.....hard to say until you identify the exact problem.
I would suggest that you ensure the fuel cap is venting and that the vent at the bottom of the tank located under the front of the seat is clear and open. there should be a small vent hose attached to the nipple at the base of the tank that runs down under the bike. The hose should be open for proper venting.

You can take apart the gas cap and clean it.
You will see a nipple on the bottom of the cap that fits into an opening on the tank near the cap hinge. You can blow into that opening (or spray carb cleaner into it) to see if anything comes out the hose under the bike.

|wmsonta||Lean mix burns much hotter. Be careful you could be spending a lot of time too lean.|

|sdphill92||Last night I flushed my cooling system real good. Also tested the thermostat and it is functioning good. So I rode to work today no problems. On the way home same thing, low power under load. Fine with no load. But I was quicker to observe the overheat this time. It didnt begin to overheat till it was experiencing the power problem. It is frustrating me|

|M_Angell||I've flushed the whole system with a garden hose before. I opened the drain plug and flushed the radiator out off the bike. For the water jackets I hooked the radiator back up and ran water til it came out.clear. next I ran coolant and flushed 3 times. Seems overkill but I haven't had a cooling problem ever.|

|sdphill92||No worries, I just found a couple threads on flushing|
