Any easy ways to tell if you bike is overheating?

There's probably a plug on the main oil gallery, behind the cylinder block. Put
your anal probe there. That's where the oil temperature sender on my GS-1100 is
at.
When I queried the dealer about the high oil temperatures that I noticed on my
new bike, he said that Suzuki should have never installed that instrument, it
just scared riders. The OTG was disconnected when I took delivery of the bike,
so when I hooked it up, I was horrified and gave him a call.

He said that, if the gauge pegged out and stayed there, I should have the biked
trucked to his shop...

I guy I know bored his Kawasaki out, and saw 260 degrees on the oil temperature
at the gallery and got scared.

Another Suzuki rider had a GS-750. He put his probe in the bottom of the sump,
where the temperature stayed around 180 degrees, so he thought his engine ran
cool.

Your oil temperature should be kept below 240 degrees F if you want to change
petroleum-based oil at the recommended intervals. For every ten degrees above
240, cut your oil change interval in half.

280 to 290 degrees at the oil gallery is not unheard of, my GS-1100 got that
hot, so I put an oil cooler kit on it.
Then the bike ran too cool in the winter, so I taped over the cooler.

I also noticed that opening the idle mixture screws 1 turn lowered the oil
temperature about 20 degrees. So I could have saved the$175 I spend on the oil
cooler...

The old Honda CB-900F's oil temperatures would reach 315 degrees. Now that is
hot.

Actual cylinder head temperatures? About 350 to 375 degrees under the spark
plug washer is plenty hot.

Exhaust gas temperatures? Around 1200 degrees F, as I recall. Pilots adjust
their mixture by observing the EGT
meters.<!-- ~MESSAGE_AFTER~ -->

For many bikes, you can get a dipstick thermometer which'll give you
oil temperature. Gokarts are often equiped with a cylinder head
guage, with a sensor that sits between the spark plug and head.<!-- ~MESSAGE_AFTER~ -->

Cylinder head temperature gauges are availible from J. C. Whitney if
you're really fussy, but unless you're experiencing other symptoms why
worry.
Spit is supposed to sizzle at 350F. y'know.
