Have a 2013 CVO Road King 110 ci. On a road trip into Idaho with 95 + degree heat. Traveling back roads doing about 65. Couple hours into the ride, bike tends to be getting extremely hot. Checking the dipstick it's reading 308 degrees.
No catalyst or baffles in pipes. Running 20w50 synthetic oil.
Had the clutch start to fail in the heat too. Would hv to pump clutch to get to work. At hotel,  I flushed hydraulic clutch.  Oil was filthy!! Much better.
Worried about ride home tho.
I've seen many blogs about 300° ok as long as bike keeps moving? Oil breaks down around 375°?
Seems too high to me. Do notice it running worse , louder & tighter.
Did a quick oil change in parking lot this morning,. Gave the bike a rest. Back on road tomorrow.
Any quick hints??

Has the bike been tuned? From your description, it sounds as though the bike is running far too lean which would cause the heat.

Removing the Catalyst and baffles without a custom tune sounds like your issue.

As long as you're moving fast enough to keep plenty of air moving across the engine and oil cooler, and it seems you were cruising at 65 mph out on open roads, 300° plus seems a bit excessive even with 95° ambient temperatures.  Ride it hard, load it up with a lot of weight, pull a trailer, etc. and 300° isn't unusual at high ambients.  Air cooling efficiency drops as ambient temps increase btw.

As Greg mentioned, if you haven't had the engine properly tuned after gutting the exhaust system that will result in significantly lean operation which will build a lot of heat in the heads and exhaust.  High exhaust temps will cause hydraulic fluid to boil; since the hydraulic line for the clutch runs very close to the exhaust pipe you need to keep the fluid fresh and use the highest boiling point DOT 4 fluid you can find.  Shielding the hydraulic lines (clutch and rear brake) from the exhaust heat is a very good idea on these bikes.

D.E.I. Makes some very nice heat shielding for the clutch/brake/fuel lines. Available in different colors, but I do not remember what. Comes in wrapable and sleeves. I like the sleeves better but you do have to have the line loose at one end to install with them. This stuff though is amazing on ability to keep heat at bay.

Had a 07 CVO Ultra with 110. Ran extremely hot. Installed a race tuner, ran cooler.

Was never as cool as i prefer but tolerable after the tune.

Best of luck.

Can't tune the bike with NO baffles. Get a good muffler with a 2'' or 1.75'' baffle and tune it correctly and the bike will run like it should......you NEED back pressure Greg

Thanks all for the input.
Great idea & suggestions!
I
My tuner guy dynoed for max hp, I'm going to chat w him for suggestions.
See about baffles as well.

most folks tune for MAX hp...

then find out they really NEED decent mid range manners.

most of us ride 50 to 80 mph.. stock hp will do that nicely.

when i was young [long time ago] i chased hp too, i also chased loud pipes. expensive and irritating.

now i want RELIABLE and reasonably quiet.

for each there own

Tune it with a flash tuner by a qualified dyno shop. And get head fans.  Open the lowers or take them off speakers and all.
