Default Normal oil temp?

I have a '98 FLSTC Evo with carb. I just put a temp gauge type dipstick in my oil bag and was just curious as to what I can look for with regard to a normal oil operating temp range. I ran it yesterday for about an hour and the oil temp was approx. 175 degrees. Air temp was about 65 outside.

That's about what my '87 Sloptail runs on a 65*F day. I'll get to 200*F, or a bit more, on a good hot Texas summer day.

Do you guys know what the hottest temp your oil should get to before it's considered a problem?

Do you guys know what the hottest temp your oil should get to before it's considered a problem?

In the TC engines which run hotter than the EVO's when you reach normal operating temps on a hot day, Anything much over 250+ should be the candidate for a cooler and possible some sort of attention to fuel remaping as it is probably running lean and complication the issue.The evo's usually run around 200* plus or minus as a rule. TC engines run comfortable between 200-250 * depending on conditions. Much above that will damage the engine oil especially if it is not synthetic. The breaking point for dino oil is around 250* where as the synthetic oil can tolerate 300*. Not good in any case but can make a difference. Engine ignition timing in the evo's can make a difference in temps also.

Some interesting facts ... https://www.hdforums.com/m_190022/tm.htm

My bike runs about 180-200 deg during the summer months.
When stuck in shore traffic it goes up. Am going to install a cooler on it.
Anytime it gets to hot (over 240) i do an oil change. Oil is cheap.
A modified motor cost MONEY to replace. IMHO
