Does your fan come on at temp?
How hot does it get?

dgk600f4i 08-24-2013 03:49 PM

Yes fan comes on gets up til 250 260 ive seen it i always shut it off when it gets that hot. Also the tempature will jump 20 30° at a time say 200 til 230 then back and forth like that.

Next step is to make sure the thermostat is opening properly and the cap holds pressure.

dgk600f4i 08-24-2013 04:22 PM

How do you do that not even too sure where the thermostat is located

Its located in the housing near the throttle bodies.

To see if its working in the bike, start the engine from cold. The lower hose wil gradually heat up, while the upper hose should be cooler. When it reaches temperature, the upper hose will quickly get as hot as the lower hose.

Or, you can take it out and put it in a pot of boiling water. When it gets hot, you will see it open or not.
