I'm with ya Robby.
I'm regularly seeing temps of 290+ as well monitored by the PV shown by ET. I've taken quite a few notes on ambient temp, ride time, traffic, highway etc on my past 20 or so rides. I'd bet if it was 75* and I was in semi rush hour traffic for 20 minutes I'd hit 295+ ET according to the PV and 260+ oil temp according to HD's oil temp dipstick.
Thus, fans and oil cooler will be added in addition to relocated permanent oil filter, exhaust, PV, external breathers...
I'm also not sure how hot is too hot but I have seen that during auto tune, the PV will stop recording info after ET surpasses 300*. Sounds like a good shut-er-down figure to me.

I wasnt paying attention to temp until Dakota Digital alerted after reaching 300, which is where the alert is set at by default.

Go to the Dakota website and figure out what gauge you have. The web site tells you what temp sensor/sending unit the gauge is reporting. The combination speedo/gear/RPM/temp gauges that I saw on the DD web site for Dyna's measure head temperature. Head temperatures of 320 are normal.

People on this thread are talking about head temp, someone is saying 260 is extreme, which to me doesnt seem right.
Where did you get the info that 320 is normal for head temp?

As far as I know, DD can only report the head unit temp, which is available through ECM. There is no oil temp built in for Dynas, therefore DD wouldt be reporting any oil temp.

If the DD is reading values off a CAN bus, it can read 2 temps as they are both available. One is head and the other is engine.. Do you know which it is?
What is the model / year and are there any mods to the bike? (you don't need to tell us about the chrome)

Head temperatures are well above what that sensor is reading, and the rear cylinder head would be even hotter.
In the Power Vision, that sensor data is called engine temperature (ET) and the cylinder head temperature (CHT) is an algorithm based on engine temperature and intake temperature (IAT).
The actual head temperature at the front is much higher than the sensor indicates and the rear? Who knows
That's why getting that lone sensor temperature down is important...

One is on the cylinder, where is the other one coming from?
DD MCL 3212 reports the cylinder head temp only..

There's one sensor, it's located on the front cylinder; but it's not giving a true head reading, it's actually located well below the head. As I posted before, HD put it in the sweet spot
