Operating Temp.

Cowboy Dan · Jan 14, 2009

Recently I noticed that the coolant tank on my RSVR was empty after checking it a few days earlier. There were no signs of a leak anywhere but I wanted to be sure. I figured it was just all in the bike or something but it still should have something in the little tank. I decided to check harder and eventuly I replaced the coolant with that EngineIce stuff just because. Since doing so the bike doesn't stay around the temp it used to be. Before, it would stay in the 170s and I never noticed it higher. Now it goes from 172-204 (172 while riding and 204 if stopped at a light for long). Does anyone have any thoughts?

Did you bleed the air from the radiator when you replaced the fluid. If you didn't you will have a large amount of air trapped in the top.

If you didn't, remove the cap on the radiator top and the bleed screw just to the right of it. Put the bike on it's side stand and top up the fluid till it comes out of the bleed hole.
Then run the bike with the cap on and bleed screw in for a while then repeat the process of bleeding when it has cooled enough to open the cap.

then top up the expansion tank once all the air is out of the rad

I did bleed it once but I guess I just need to repeat the process a few times.

Thanks for your help!

If you have emptied the system then you have to bleed it once cold as a preliminary before running the bike but then again after it's warmed up.

The thermostat is closed when cold and will trap air especially in the rear cylinder jacket all of which will rise to the radiator when the bike is run and the thermostat opens. Then the second bleed should finish the job.
Make sure it's on the sidestand though so the bleed point is highest on the rad.

Excellent info! i was wondering why mine was always close to 200 eventhough the reservoir is full. I'm gonna flush mine soon, I'm still looking for the magic flush plug before I get frustrated and disconnect the large radiator hoses on each side. they have been getting on my nerves lately they are a little short and they used to leak.

The plug on mine is on the opposite side of the radiator fill opening at the bottom. (left side of bike) I have an 08' so I don't know how it is on older bikes. Hope this helps!:dunno
