Fast Idle Woes Continue

[fixitsan]

I've got a slightly different problem. CSM works fine from cold to normal temps, but if the engine gets hot, such as in queuing traffic, the idle speed rises again. It has also puked a bit of coolant when very hot. Any thoughts? I'm wondering if the pressure cap spring is a bit tired.

Is the fan thermostat functioning ?

On most bikes the fan comes on before you get into the red zone, but mine originally came on only when it was very hot.

 

If you're not sure, just let it idle and wait to see if it comes on before the temperature gauge reads maximum
