my bike keeps over heating thermostat is not bad cuz i took it out and left it out i do have a new one to put in, i do have the fan wired to a switch and leave it one all the time, coolent good all full i use the kawi green coolent, so what else could it be ? thanks

 

Sounds like you have the basics covered.

1. Put new thermostat back in.
2. Make sure there is no air in the system afterwards.
3. Make sure fan is spinning correctly. Should be pulling air through radiator.
4. Make sure oil is clean and full. Make sure oil cooler is not clogged.
5. Make sure coolant is at the proper level in the overflow bottle.
6. Make sure radiator cap is good. If in doubt, replace it.

What conditions does it overheat?
What temperatures is it running?
Does it boil over into the overflow bottle?


That's all I can think of right now. Beyond that, you get into high engine compression, lean running conditions, brakes dragging, or timing problems.

Hope that helps some.

 

You should buy one of wetter to see it it works, i forget what its called but worth a shot. tho

 

shouldn't overheat without water wetter. Find the problem first.

 

i'll def check it all , its was like 75-80 today and i just ride lots, i don't know how to change the gauge back to f and its on celceus gits up to 110c -120c 116c-119c is flashs and at 120c its just says hot and flashes so once it git to 115 is turn it off

 

Yep. You are overheating.

120C is almost 250F! That is getting into critical damage temperatures.

Since the thermostat is out, remove radiator cap and look inside radiator and make sure coolant is circulating. Then start checking everything else.

 

there u go water wetter ...i would check everything what he just said ^^^^^ or it could be water pump but i highly doubt it tho.

 

thats what i thoughtr is was the water pump but i dunno, how do i know if its circulating? and what is water wetter?

 

there you go .....

 

Sorry,

With the thermostat still out, remove the radiator cap and start the bike up. Then look inside of the radiator and see if the coolant is flowing through the radiator. It will be obvious.

If the coolant is flowing, the start checking everything else. If there is no movement what-so-ever, the time to look at the water pump.

 

tokwik has you covered but i would like to ad one thing , when your bike starts flashing instead of turning it off shift the bike into 6th gear and just cruise around a little to get some air across the radiator , that should help cool it off

 

BTW i wouldn't keep riding the bike until you find out why your bike keeps over heating cause eventually your going to pop a head gasket. When you did the fan switch mod are you sure it was installed correctly. Is their a possibility that the temp. sensor its fried and maybe your bike isnt overheating you cluster is just reading that it is?

 

my bike was over heating and i used this stuff ; it helped out a little but in the end it would keep over heating .. i finally put a thermostat in monday and now she is running perfect

 

i got the same year and same problem and just blew a head gasket...
so if you find out exactly what it is let me know thanks.

 

I run engine ice, wrapped the headers, and hardwired the fan. Still runs around 205 and the hottest I've had it this year was 225 after doing burnouts.

 

how long did it take to blow that head gasket ???

my bike was over heating for a couple of stunt sessions but didnt blow a gasket

 

my fan spins counter clockwise is that right? i' gunna have have my buddy help me tomarrow put the new thermostat i have in and flush check and fill it back up

 

+1854168165 that's what i do, helps alot

 

counter clockwise right or wrong?

 

i changed the oil in the bike and a couple days later it started leaking out the front of the head.
but it seems like it only leaks when im at high rpms doing stoppies and stuff..
