burp my rc?

im gonna be swapping over my rad temp switch and gonna add a load of water wetter to my coolant/antifreeze as my bike is running very hot at the moment, even creeping along at 20mph my heat builds up. gonna burp the sys too while im at it, just incase this is whats causing the bike to heat up so much.

just need to know whats involved in burping and how to do it

Make sure your bike is on it's side stand so the bike's lean will help with burping. With the radiator cap off, start the bike. I just gently roll the throttle on and off to about 3 or 4k. When your bike reaches about 167F degrees, that's when the thermostat begins to open. You'll see the coolant begin to move a little in the radiator. By about 172F, it's full open and you should see the coolant moving rapidly in the radiator. That's when the bubbles start coming out. The last time I burped my cooling system it took a couple minutes for all the air to work it's way out.

What you say about the cooling sounds pretty normal to me. In warm temps, I do not get much cooling below 40mph unless the fans are on. The temps slowly climb until the fans click on. I installed a manual switch so that I can turn them on when I will be cruising slowly.

im in a town, surrounded between 2 cities. trust me, a manual switch would be a dream, but dont have the experience to do something like that.

will try this for now.

Wiring a switch for an SP1 is so easy that you will laugh after you have finished it. The hardest part of the procedure is deciding where you want to mount the switch and mounting it there. The rest is simply running 2 wires from the switch to the new temp sensor that you are installing.

He doesn't even need the lower temp sensor. There's a little issue with the o-ring on that mod anyway. I did it, and it didn't make enough difference for the hassle. I'm back to a stock sensor.

Just install the toggle switch. Your fans will still kick on normally even if you forget to operate your switch in the correct position. Actually, it would be a great little entry-level mod. Very low difficulty level.

Unless I missed a thread where this was previously resolved, his temp switch was not working and the fan was not coming on at all. He ordered a replacement temp switch to make the fan operable again.

I highly recommend the manual fan switch mod, but you obviously need the automatic switch to work too.

Oh -- I thought Polarbear was talking about the lower temp sensor mod. My bad.

My original "switch mod" was ghetto as hell. I just ran two wires all the way into the tail where the fan relay is on the SP2, took the metal terminals out of the plug, took the stripped ends of the wires I ran back there and put about half of the strands over the top of the terminal so the plug would still go on.

I did it that way at first because I wasn't sure that it would even work (this was before I had ever heard of anyone else doing a manual switch for the fans). It worked for about four years. I think I finally redid it a while ago.

If you have an SP1 polar bear, you just need to put a switch between the two terminals in the plug on the left radiator for the thermoswitch. Should be very easy.




I'm always right.
