[h=1]Harley Overheating[/h] Q: Hello, hope all is well with you. I have a simple two part question for you. What is the normal operating temperature (engine) on a 2007 road king classic with a 96 cubic inch motor.. and what kind of temperature readings should I expect to get on the head pipe between jug and O2 sensors?
I have a super tuner, big sucker, rush ceramic pipes and rush mufflers with 2.25″ baffles. I get about 324-340 degrees F on jugs right beside the spark plugs, and anything from 560-700 degrees F on the head pipes. Is my Harley overheating? Any info would be great..
Thanks
Bill
A: Hi Bill, Standing at idle for how long?
324-340 not bad and if you are driving down the road it would be cooler.
The trouble happens in traffic or any long periods of the bike running and standing still.
Passenger comfort, hot legs, from the rear cylinder and exhaust are usually the issue.
You can install an oil cooler to help the m/c run cooler and a cylinder cooling fan to also help cool when standing still.
