I've never changed my coolant myself, but I've heard others say that 1 - it could be the type of coolant you use, and 2 - you may need to "burb" the system because air is trapped in there somewhere. I "added" some 50/50 to my system the first year I had my bike cuz I noticed it was running hot and the coolant was low. Had the dealer flush it for me this year, and noticed that it runs hotter and the fan kicks on a lot. So I'm thinking of draining some of whatever the dealer put in and add some more 50/50. Anyway, do a quick search on burb and I'm sure you'll find it.

EDIT!! I'm pretty sure you mean "burp", or "burping the radiator", something like that... GO 200

Take it to a mech that you turst to check your system.
If everything looks ok have the head gasket checked and the head it self for cracks.Do not use any kid of radiator sealants and do not spend time changing parts like the thermostat if the temps are not normal.Check the head.

The cooling system is a tricky thing to mess with..

What exactly did you do when you say flushed my coolant ?
what brand and mix did you refill with ?
Did you forget something simple like rad cap not tight fan unplugged ?

I did this very simple and cheap I put up some pics soon.

From bikeland:
Its simple the are two wires on the thermal switch located on the left side of the radiator. You just tap into those two wires with a togle switch one leg of the switch on each wire. To test the method just put a jumper across the two wires and the fan will come on. I found that the cooling sytem its self is fine its the fans dont pull enough air through the radiator the rpm on the fan is to low.

Sounds like there may be air trapped, I agree you probably need to burp it.
Don't forget the "Water Wetter", the stuff works wonders for hot running engines.
Go with 75% water, 25% glycol, and 1 ounce of water wetter per quart of water/glycol solution.
Guaranteed to run cooler.

I allways suggest to switch off the engine when you know that you will be standing on a traffic light that will be red for a minuete or more and on long descents.
In addition with a fan switch that opens earlier it is a good combination to keep your bike from running hot less.

Mine developed an overheating issue after a highside a few years back. I chased the problem for six months thinking the fan switch wasn't working because it would start to boil right before the fan came on. So I wired up a manual fan switch and that helped some. Then one day when I had the plastics off I opened the radiator cap to check the coolant level again. It didn't look too bad. Then with the cap still off I gave the radiator hose a good squeeze. A huge air bubble came belching out. I squeezed a few more times until no more air bubbles came out, repeating the proceedure on all hoses i could reach. I topped off the coolant, buttoned 'er up and it has not overheated again to this day.

So my bet is air in the coolant system and the "burp" is what it needs.

I should have thought of it much sooner as it is a common problem on snowmobiles too.

Yes!Parts like thermostat and switch are unlikely to fail.Most of the time burping,cracks,leaks are usualy the problem..
