"Design" oil temp on the Twin Cam motor has often been reported to be 230* which is a pretty normal number that youll see after 20mi of highway riding in 75-80* weather. Ive seen 250 or so in 100* temps. Temps in stop and go traffic can be higher.

2015 RGU CVO........under continuous change......

I live in Tallahassee and just rode up and back to Greensboro, GA. I had the dealer install a Reefer oil cooler and a HD factory oil guage.

On I75 at 75-80Mph during the late morning, bike ran at 205-210 deg. We got stopped in traffic for a few and were going nowhere fast for 3 miles. Bike quickly jumps to 230. It did not get any hotter. I did, however!

On return trip, in the cooler am temps, bike ran about 190-200 down same stretch of I75. Hit traffic back home and back to 230.

You can park bike for lunch and return and these engines will drop 50 deg in an hour. Amazing.

Just a real case example. I hope this helps.

On the newer 103 Twin Cams 230-260 is normal. In 100 plus temps and stop and go traffic 280-300 is normal.

If you didn't have the Reefer, you would see the temps go a bit higher, I know because I had my oil temp gauge before I bought my reefer, for extra cooling you might also want to try engine cooling fans. BTW welcome to the forum from Miramar.

+1... I had the same concerns when i installed the oil temp gauge. It was comfirmed that the twin cams will and do run temps up to 300°.

Pretty much as stated above.....did 800 miles across northern NM and back doing speed limit plus 5. When relatively cool, 200-215, warmer temps above 85, around 220 with an occasional 230.

May I add that I understand 250 plus is normal, but I still am gonna get a slight "pucker factor" when I see 250 plus going to Shark Week III.

Sumax the powder coating folks, that we have built MANY bikes for, locally, had us perform some cylinder head heat testing for them about 10 years ago in our oven we use when we used to(still do occasionally)re-sleeve cylinders.
At a digital recorded 350*, the valve seats WILL start to migrate in the head, FWIW.
