Title: BOILING WATER
Post by: jpinhb on November 26, 2006, 02:51:48 PM

Hey guys , it's been a while since I've been on and I need some advice . I went riding the other day and noticed that after a few hillclimbs my bike was hot and I could hear the water boiling . I went back to camp and it was very low . I let her cool off , added some water and went out again , same problem . Is there a simple way to pressure check for leaks ? There were no visible leaks that I could find . Anyhelp would be appreciated .

First, check your cap. More than likely it is not allowing it to pressureize and is coming out the hose.

Also, check your oil. It could be leaking into your tranny (bad seal). Lastly a small leak. Go to a local hardware store (Pepboys or Advanced Auto) and rent a radiator pressure tester. Or find your mechanic friend who has one.

But more than likely the cap has worn out and isn't holding as much pressure.

Purging all the air out of the cooling system is very important, their is a air bleed screw on top of the head. This screw needs to be cracked open while you are filling the cooling system.

I also think you should check(or replace) your cap.  It is a good idea to route the overflow hose onto the pipe. Then it is easy to tell when you are boiling over (steam).  I run an overflow bottle on mine since I often ride in slow/gnarly areas.  Seems to work well.  There are some pics in my gallery - easy to fab out of an old armourall bottle.  Cam.

I have the same problem, where do I find a new cap? (I have a 89' kx500)

Hey, welcome to KXRiders! First I would start with your local Kawasaki dealer.. Next an automotive parts store usally has them too.. It is a 1.1 bar cap, and most parts store have the correct size. But as always check with Kawasaki first to see if they have one.

Is there anywhere online you guys go?  The closest Kawasaki shop around here is kind of far.
