Got me thinking Matt, I still have a Mychron gauge from my kart racing days, we used to monitor and data log head temp and exhaust gas temp, and a few other things, used to shoot for 375-420 head temp running methanol, to high of a gear ratio or being too tight on handling and temps would shoot up.
I’m guessing 350- 380 should be good on the HD,
I’ll be doing some carb maintenance on the 111 soon and going to recheck afr and probably check both cyl head temps with dual readout Mychron just because. Interested to see the relation between the AFR and HT’s.
What's the temp in the Blue & Silver can? Hope all is well with you and the family. Wolf on the road again?
The temp is just right, We doing OK, Wolf's not back in the wind yet, he did ride a trike I had here a while back, he's doing OK though, hope everythings well on your end.

Thanks for the info, tell Wolf I was thinking about him. Life good here, just getting older, Waiting for the next EVO to come out from hiding.
Now back to the EVO Head temp gentlemen. Carry On.
If one wanted to read head temperature, couldn't I just use an infrared laser thermometer? It doesn't have logging capability, but at least I don't have two unsightly wires on my engine. Plus I now have the ability to measure other points on my motorcycle, like exhaust, electrical circuits, etc.
Probably a bit too technical for some, but infrared thermometers are often off due to the IR emissivity of the surface being measured. Highly reflective metals have very poor emissivity and therefore give inaccurate readings. Oxidized metals typically yield more accurate results. I have been dealing with the IR emissivity of metals for over 40 years. Fluke makes good adjustable meters that are superior to low end devices (much more costly though). How accurate do you want to be? That's the question.
the pics i posted earlier where the wires for the eyelet are to the left of the spark plug is not how i route it. i put it directly behind the spark plug and the wire goes up under the fuel tank....it's barely visible that way. the eyelet needs to be bent at a 90 degree angle so it follows the rocker covers to under the tank.

I might buy some 12mm ones just to have them for future projects. They're great quality.
