Temp Issues

Postby portugeezer » Fri Jun 06, 2014 7:58 am



So last fall my bike started to seem to never warm up according to the gauge. I replaced the thermostat. The old one didn't seem stuck. The needle does move but only if I'm sitting stopped. Could it be the temp sender? I ride the bike and it seems to cause no issues. I feel a lot of heat coming off the engine. What else could cause this?

Does your cooling fan ever come on? The temperature switch that switches the fans on when the coolant gets hot is separate from the thermostat.

It could be that your cooling system is running just fine, and you've got an issue with the indicator - either the sender like you mention, or the regulator that runs the temp and fuel gauges. If both your temperature and fuel gauges are always reading low (regardless of fuel level) then your problem is most likely the 7 volt regulator.

The fan seems to come on when it should according to the gauge. The other day it was 85 and I was riding on some country roads. If I was going north the gauge was as low as it goes. I turned east and it went up about a quarter of the way. If I'm going fast it always drops all the way down. Not sure what the hack is going on.

If your fuel gauge goes full when you fill the tank, then the sender seems to perhaps have a bad connection or has corroded inside.

Kinda Piggy backing on this topic......
78' gl1000
I had a small leak in my radiator (bike worked fine before then) had it replaced (also had a front fairing put on at the same time) and now the bike heats up fast.

I can ride on the freeway just fine the moment I wait at a light on the exit the temp gauge goes up fast (fan is on)! I recently pulled into a gas station after a short freeway trip and stuck my hand between the front tire and radiator and there was no air movement just hot air. I then put my hand behind the fan area and felt air movement.

Would putting a faring on cause the radiator to heat up faster? Is there a way to clean this "new" radiator in order to let air pass through?

Thanks!

Could the fan be weak and slow. I am not sure you have a radiator concern or fairing concern as they would show on the freeway too. So I think weak fan or weak water pump.
