how hot

rode about 50 miles today, mostly at 65-75MPH, around 4-5K on the tach. the engine was HOT (not so much on the gauge but it burned my legs on the foot pegs)

the fan never kicked on even above the halfway point on the gauge. again, never reached past 3/4 of the white...

this normal? i checked the coolant level before i left, seemed good to go.

thanks!

I'd be checking something. I did a ride last week when the air temp was 102 and my fan kicked in quite often. It always turns on when I stop at a light or when I turn off the engine.

Anyone use the products that claim to lower the coolant temps like 20 below?

Thats a bit hot I think, check the fan as it should be kicking in especially when stopped, but also the thermostat if you have fluids... I don't think that when you are moving it should get hot past the 1/2 way point to speak of, and if the fan was kicking in even when stopped...
I tried some coolant stuff I got at china-mart, but didn't think it helped as it said it would (15-20*)... I couldn't tell any difference hardlt at all, but I can't remember what the brand was...

to be honest, im not even sure ive ever seen the fan kick on.

I don't mean to state the obvious but make sure your temp gauge is working properly as well.

There are a couple ways to manage engine temp while you're riding too. You can try those if she's over heating. Coasting downhill with the clutch pulled in, pausing for a few seconds between upshifts (if you have room on the road of course), and trying to keep the rpms around 31 or 3200 regardless of gear or speed may help...

My fans run at between 1/4 and 1/3 temp on the guage. It's never been over half and that was a 3000ft climb in about 15 miles, two passengers.

First step is pull the connector off the fan and jump 12V to it..... see if the fan even works.

You might try turning the switch in and out a few times (to clean off any corrosion) and cleaning the electrical connecton, then go for a ride to test it first. If the fan still doesn`t work, then do the boil test.
