Kawasaki Problem

[kawiMoto]

Hi guys, so my kawi ER6-n keeps over heating when I'm going slow I did have a problem with the coolant a while back it went seriously minging, I have flushed the crap out and it's staying clear but if I go on say a bike meet and ride slow the red light comes on until I give it some welly to cool down.
Has anyone experienced this problem?

Does the fan switch on?
Could be a thermostat issue, or a blockage in your system.

Yes! somone has mentioned the thermostat before but with the coolant bubbling out i think the thermostat is correct any tips on finding a blockage ?? thankyou

Im no expert but I did google a bit now.

Does the fan come on? If not then your thermostat is shot, or not getting a connection.
If the fan comes on, do a flow test on the radiator.
Maybe flush the system, and visually inspect the radiator, sometimes the inside flows correct, but it becomes "flaky" inside causing the radiator not to function correctly.

But first confirm if your fan is working/thermostat.

there is a radiator fluid that would probably help you out. i forget the name of it but you don't add any water to it and there is a special fluid you need to flush your system with but it has a way higher boiling point and will reduce your running temp. thermostat would be easy to check just grab both radiator hoses if they are both hot then it is circulating. your fan should come on before it boils. also you can get a lower temp thermostat which might solve all your problems.

the fluid is called evans.

Thankyou for that I'll give it a look and I have never heard a fan on my bike nor can I see one :l air cooled maybe

You do have a fan between the radiator and the engine. It should kick on about 90c that's before the coolant will boil. The temp sensor could also be bad not telling the fan to switch on. it's in the head on the left of the engine, just above the starter motor.

I am leading to believe you fan or therostat is not working.
When your bike starts getting to the point of overheating, check to see if your fan is blowing.
If its not, then isolate that problem first.

Thanks for the help guys ! Really appreciate it ill check when I next get a chance to warm the bike up and let you all know

Any luck yet finding the problem?

I'm pretty sure the thermo stat has gone ! I took it out yesterday and the fan didn't come on once looks like I'll be taking a trip to the garage soon

On the ER6 the fan should come on quickly within a min or two of standing still. Its a small fan but even with a helmet on it makes a distinctive whine. Hope the fan it self isnt buggered as that is a costly part!

If the fans not coming on it would be the temp switch not the thermostat. You can check the thermostat just by feeling the hose on the other side of it going towards the radiator. If it's hot then water is flowing past it.
