Help, Overheating

I have a 06 VRSCR with 2,000 miles. Yesterday I started getting an overheat indication. I searched the forum and checked the following:
New style coolant tank is full
Pulled plug in airbox and only managed to add 2 ounces.
Checked under alternator cover (left side 2 screws) and everything seems ok.

The fans are running a lot and it happens at both low and high speed. The engine is obvoiusly very hot but the radiator hoses are not too hot to hold. Outside temp about 60.

What do the experts think, stuck Tstat?

Thanks,
Mike

Check the triple sprocket bolt first, if it comes loose the water pump won't spin correctly. If that's still tight, pull the t-stat. Did you check the radiator to make sure it's not built up with leaves or whatever?

Are you sure both fans are turning. Like he said not full of leaves.
I agree sounds like thermostat to me.

As I understand, you are talking about the bolt under a cover on the left side of the engine held on by two bolts. Is this correct? What is the torque supposed to be on that bolt? It looks pretty big.

I would check the triple sprocket also... they can and do back out, some have been known to be loose from the factory.

Check raditor also...clean...check to make sure both fans are coming on.

Check the manual for bleeding the system and do that.

Check cap so it is tight and not losing pressure.

Check bleeder screw to be tight.

Thermostat would be the last thing to dive into...you will have to remove alot to get to it.

The stat itself is not sold as a stand alone part, you have to buy the whole housing and all for 100.00

Good Luck

As long as you're not getting air bubbles in the coolant, I doubt you hurt anything.

The shaft drives the water pump, not the oil pump. With the bolt loose, you lose some oil pressure to the top end, but it should have gotten noisy if you went without oil for very long.

Where can I find more info about the triple sprocket bolt's backing out? This happened to my 07 VRSCDX, Its currently been at Mobile HD for two weeks, and Im looking for documentation on this problem and it's frequency. If this is a known & recurring problem I shouldn't have to pay to have it fixed, Thanks

My 06 vrscr was two weeks out of warranty. HD area reps backed their product and took care of it no charge. The northeast and southeast reps seemed to be well aware of the problem. While in the shop, they also replaced a water pump, tstat, and housing due to a very minor seep. I took oil samples and indication was no top end damage.
