over heating

[sohaver]

I have a 1979 gl 1000 the temp gage slowly goes up and stays up, I have changed the water pump, thermastat, and by pass the fan it stays running, can anyone tell me what else might cause it to stay hot im lost

[dkorody]

it could be rad cap or your rad could be full of scale

[sohaver]

i have also flushed the radiator

[dkorody]

i would check and make sure the rad cap is pressurising i had a car do that and nobody could figure it out put new cap solved problem

Sound like air in the system, and I agree the cap is a good part to check.

[sohaver]

how do you get air out of your system

[sohaver]

is it normal for cooling fan to blow air out the sides down by your legs?

[dkorody]

when did this start heating ??did it just start heating all of a sudden?how long does it take to get hot?

[sohaver]

I just got the bike 3 months ago and this started 3 weeks ago coud the weather have anything to do with it

[dingdong]

Can you describe what you mean when you say "goes up and stays up". How high is up? Does it get into the red?

[sohaver]

No it doesn't get in the red it stays right on the edge it takes about three miles

I have said it before but it is worth saying again.
Get a reading from an accurate thermometer. digital is a good source. DO NOT trust the gauge on your bike 'till you "KNOW" it is right.
