I need some help getting a thermostat

Anyone know where I can get a thermostat besides the dealer or ordering it on line. Someone had listed a some compatible rad caps but having trouble with the finding a t-stat. Even when its not hot it still gurgles a lot through the cap. Oh ya it a stock 03 with 17k.

Sounds like the problem is the cap or cap gasket, rather than the thermostat.

If you have a friendly auto parts store that will let you peruse their selection, take a look there. The EX500 folks found a standard auto model that was a direct replacement for the 49054-1059 - less than $10 and available on every corner. The only difference was that some of the auto models didn't have the bypass hole. That's the only flow in the cooling system when the thermostat is closed, so make sure it has one, or add it yourself.

I think most of Kaw's thermostats are going to be 49054-####, so I wouldn't base swapping parts just on the first half. The alternate part number you posted is for the Mule. I know nothing about that engine, but it seems like it could be quite different from the 250's. Looking at the parts diagram, it looks like it might be mounted right on the engine rather than in a remote housing, so the temperature could be quite different. At least the 500's part number is only 1 off the 250's and the bikes are fairly similar, if you want to try random alternate parts.
