Everything? Like checking that the waterpump impeller is not slipping on its shaft? Does the electric fan work? Head gasket ok? When does it overheat? Slow traffic? Fast traffic? Mister_T Melbourne Australia> need help on how i can get my klr 650 1987 to stop overheating. i tried everyhting but replacing the radiator. it looks good to me. i took off the thermosat and it still overheats. also i changed antifreeze with redline. it still overheats. please help. thanks john
Can you be more specific about overheating. I have read where people see the needle on the meter at the 2:oclock position and call this overheating. Is your needle at the far right position and in the small red square? Normar operating temp is between 1:oclock and approx 2:30.>need help on how i can get my klr 650 1987 to stop overheating. i tried >everyhting but replacing the radiator. it looks good to me. i took off >the thermosat and it still overheats. also i changed antifreeze with redline. >it still overheats. please help. thanks john
Are you loosing coolent? Check at the radiator, not the overflow tank. This tank can be misleading. If your coolant is low - are there any water leaks? Check the hole under the waterpump. Maybe it leaks only when your riding? Check it at idle, rev the engine some.>Everything? Like checking that the waterpump impeller is not slipping >on its shaft? Does the electric fan work?

I don't own a KLR650,but have seen in other engines a situation where the water pump impeller brakes loose,or slips on the shaft that drives it.I have also seen impeller blades brake off.Your radiator may well be partially plugged with deposits.Yours is a 1987-thats quite a while to run a radiator.Is it possible you have a blown head gasket-putting pressuer in your cooling system?Have any 650 owners had this happen?Is your cooilg fan coming on when it is supposed to? Just some ideas to check. Jon Neet>>
