Cylinder Head Temperature Gauge: Do you run one?
#1
![Default](https://www.hdforums.com/forum/images/icons/icon1.gif)
2000 Electra Glide Ultra, 100" TC engine, 570 cams, MM fuel injection, no factory CHT gauge
Due to serious concerns for the health of my engine after the break-in of my rebuild went terribly wrong, I'm thinking about installing an aftermarket CHT gauge so I can be aware of when my engine is getting hot enough to risk risk damage so I can take steps to cool it off.
Do you run such a gauge? If so, what do you run and are you happy with it?
Also, I'd be glad to hear thoughts from informed minds on the topic who are not running one.
I see people commenting that such a gauge just gives you something to worry about, but damn, after what I just went through and the cost to correct it, I'm willing to take on that worry.

I see no need for a CHT gauge and rely on oil temp. I have neve had an overheating issue with the all bore 107 in my 2002 FLHT but if oil temps start passing 250*, I know the motor is getting hot since normal oil temps even on a hot south Texas summer day never pass 225*. Time to pull over and cool down or find a back road to get out of the traffic.
If truly concerned about head temps, get a set of Ward's fans or Love Jugs; not sure is Ward is still selling his fan setup.

Just rode the bike home with new pistons and cylinders, and rear cylinder got up to 370 (with a good quality hand-held infrared sensor), while the front was 100 degrees cooler.

I read your signature it would seem your AFR is maybe, perhaps might be a fudge lean if your CR is up ..I dont know if it is.

Now back to the regular. crap.
CHT is only a value at about 100% load.
if you are topping out just riding you HAVE TO BE too lean.
Next - i ask who is going to dictate too high?
I run 10 .5 with cast iron cylinders, a fat AFR and all is well.
Its like beating dead chickens here, they dont learn or move.'
The only thing changed in the last 100 years to make a POS HD engine run hot is the LEAN AFR!
fix it!

I would not worry about 13.8 AFR at WOT; the motor does not see WOT very often; partial throttle AFR is more important. You cannot adjust timing with the Power Commander and I would suggest upgrading to the Power Vision and a proper dyno tune and an oil cooler.
