Reply to "Head temperature gauge"

Everything Danny said is good info, and I would add that, since this is an air cooled engine, normal operation, different speeds, idling in traffic, pulling up a long hill, are all going to cause the head temperature(s) to vary.  Sometimes a lot.  As Danny stated, the "normal" temp swing could be well over 50 degrees F.  

So you're halfway up a hill and just happen to glance at your CHT Gauge and, "HOLY HOTSHOT"!  It's kinda up there!   But you keep driving and once you're over the hill and heading down the other side the CHT comes back down to something lower.  

This is normal.   Aircooled engines swing CH Temps a lot.

You could also question the folks on here as to how many have a cylinder head temp gauge in their car and, of that group, how many actually pay attention to it while driving. I'm betting it's a small-ish group.  That would also lead me to ask @aircooled Bruce why he removed his from his car.  Maybe it was just another gauge that he doesn't have to worry about (after realizing that the engine operates in the same range whenever he goes out?)

I'm not saying a CHT gauge isn't useful, it is, but only for a limited audience and for limited circumstances.

Just my 2¢
