RE: hot ultra?
I guess if I'm riding an air cooled engine in 100 degree temperature, I'd be just a shadestupid to think my oil temperature wouldn't be kinda hot. I have a friend that worries about his oil temperature constantly. Checks it every time we stop. He pulled off the lowers and installed an oil cooler that, incidentally, works when you're moving. What works best for me is toignore the oil temperature and ride the thing. If it pukes, I'll get me another one.

Sorry to disagee, but one should not get burnt while riding, unless you touch the pipes, heads, etc. The '07's prolly won't blow up, but they get hotter than any other EG or RK I've had the pleasure to ride or own. that includes Shoveols, EVO's TC88's and the TC96. You should not have to bear the cost of retrofitting a stock bike so it will run coller. I am willing to meet the MOCO half way, I love my Ultra, but I an't spending my $$$$ to make it cooler.

Oil coolers also work when sitting still- just not as well as when air is moving over them. As long as the surrounding air is a lower temp than the cooler itself it'll radiate heat.

$180 for a Fuel Pak to cure the EPA-imposedlean condition and coolthe bike off and you're done. Hell I've spent that in one trip with the family to a nice restaurant.

RE: hot ultra?
Thanks again for the positive comments. SMenasco, we have identical bikes. I have the same color scheme. Rode again today in hot and humid temps after work. Oil dipstick read 101 cold oil after sitting still for 7 hours. It was hot today. I think dipstick is accurate, as heat index temps today were supposed to be around 105 with air temp 95-97. Rode for about 1 1/4 hours, and dipstick read 248, about the same as yesterday's 249. Using this as a gauge, I may try running it with lowers off tomorrow and see how it compares. Oh, wait, I can't use an inaccurate dipstick this way can I? MPG also improved this tank. Rode a bit more conversative and got 36, close to the 37 I was getting stock. I suspect it will get slightly better with more miles, still only 1250 on the bike.

PCIII cooled it down for me. I have several maps that I use. I use a richer one in the summer to cool things down.A lot more comfortable. No longer goes in heat management mode.

I'm lost. If the theory behind "oil coolers" is dependent on ***air flow*** across the cooler, and it is, pray tell, just how will an oil cooler do any "work" when no air is passing across it...as in, "when sitting still"?

oil coolers are certainly more efficient, and work best when air does flow over them. but as stated, they also radiate and disapate heat, much like a steam heat radiator does in a house. Again, agree that they work best when air is flowing, they do add more surface area and increased oil capacity which does have some cooling effect when sitting still.

Object A = 200 degrees. (Oil cooler with hot oil flowing through it.)
Ambient air temp = 90 degrees.
You can't figure out how Object A will shed heat into the ambient air?
I'll try to make it simple- find someone with an oil cooler on their bike. Run the engine to operating temperature then hold your hand above the oil cooler. You will feel heat coming off it- it's dissipating heat from the oil into the ambient air.
Of course more heat will be shed with air moving over the cooler, but it will shed heat with no airflow over it.
You might want to go read up a little on how heat radiators work before you get too smart-assed about it...
