which coolant is the best??
ID KX500:
I used Moose Juice, but there are others. Here's one called Engine Ice.

I do a lot of the slow 1rst gear climbing slip the clutch in the heat of summer and haven't overheated yet. I made the mistake on an older KX500 of dumping drinking water in when hot. Not good it corrodes the aluminum radiators up if it isn't distilled water.

I run this blue honda car coolant, comes premixed 50/50. I found some coolant website once that tested coolants and it was the one they universally recommended. I was told once that it is the same as engine ice but I don't know if its true (and I doubt it). My next step in my 450 was to put in engine ice but I haven't needed it. I did the overflow tank and the coolant and have been good so far with no overheating even on those 1st gear days. Cam.
2-Stroke Tom:
I remember when I used to race desert a lot, some of the people who went to flag the course that rode KX500's would run into heating problems. Temperatures reaching over 110 degrees, a big barrel to cool, and the lack of airflow through the radiator would plague some of these bikes. I know one thing that helped a lot was to run a lot more distilled water in the radiator than coolant (like a 70/30 ratio). Coolant has great anti corrosive properties and a high boiling point, but water actually does a better job of cooling the engine. I found this out when I blew a radiator hose in the desert on my van, and when I put pure water in the radiator, it ran a lot cooler. In conjunction with running a greater amount of water than coolant, it's also wise to run a higher pressure cap, as the higher the pressure, the higher the boiling point. I think Kawasaki lists various radiator caps for the K5.

Great info, Thanks for all the replys. Cam, I assume that the coolant you are talking about would be avalible from any auto parts store? Is there a specific name or is it just Honda Coolant and it is blue in color? I have had great luck with Pro honda gear oil, so I am sure this will be good.
