Have you checked the cooling system to ensure you don't have any air in the system?

I would imagine that your CA emissions stuff adds to this problem.
First off, the general consenses is to ignore it unless it goes into the red. Seems normal. Second, an easy fix is to open the idle mixture screw to about 2.5 turns. There are several other mods directed at air flow that are said to help some. I just did the mixture bit, but haven't ridden it enough yet to give you a report (snow).
Do a subject search at www.klr650.net to see some of the hundreds of plausible and not so plausible "solutions". Meanwhile, unless it is getting into the red, just ride it. Everyone else does!

For bike emissions control I have no info, but the 650 board can help you rule out problem components. I would not recommend additive fixes until you get the systems check down, if there is a persistant and chronic heting problem, make sure you run a good coolant like water wetter by redline, engine ice or evans radiator fluid to reduce heat.
In the 'General" discussion they are talking about an oil additive called two2cool.
Anything to do with oil is a firestorm controversy, this product is getting some use by local riders here with good results- see for yourself.

On many models the oil can exceed the coolant temp as much as 150 degrees. Much of the time it will be atleast 50 degrees hotter even on street bikes.
Generally when a bike is reaching high temps from slow riding/traffic conditions the reason is obvious. The rads arent working as good as they should be since there is no or little air flow.
Much of the time during slow technical trail riding or stop and go traffic you are using the clutch excessively. This only adds to engine temps. Since most coolant pumps are in the oil bath this heat is being transferred to the coolant also.
The only variable with Two2cool is how hot your engine oil is to begin with. We have seen big bore stroker harleys with oil temps exceeding 300f and sport bikes over 250 f in the stop and go traffic down the strip in daytona during bike week. In thse models overheating isnt an issue after adding two2cool. Any questions please feel free to ask. Norman

Maybe a broken water pump impeller shaft ???
I do believe we have a winner here!
There is a lot of problems with either a broken shaft or more common, a loose impeller on the shaft.
