Mid to late 70's Airhead engine temp

Does anyone have any information as to the temperature that an airhead runs at when warmed up?

I know down around the heads/exhaust manifold the temp would be much hotter than other places, but I am wondering about the engine case, oh, let's say around the starter motor? Or how about oil temp?

I obviously know that this will vary dependent upon ambient temp and speed through the wind and how well the fins dissipate the heat, but I am just trying to get a feeling for the range of temps that the engine case may get to.

I would assume the engine oil temp would be nearly the same? Right?
 
On three R100's with an oil temperature gauge (dipstick) and oil coolers I would see between 200 and 250. Once on my R80 riding double and stuck in traffic I saw over 280, much too high for my liking.

The nikasil cylinder models--1981 on--shed heat more efficiently than the iron liner cylinder models.
 
My dipstick gauge will read between 200 and 250 when she's really warmed up. Just keep moving, I never let it sit and idle unless I'm stuck in traffic.
 
That bike of yours is one of the sweetest running airheads I've ever seen/heard. Temp range is right on. I forgot to tell you, sometimes those dip-stick gauges require "worry-beads." As you say, keep it rolling.
