Top 5 heat reduction options
Yeah but it's also amazing how much more water that lets through too. <g>
+1 - once I added these to my ride I noticed a BIG change in temps.
Unfortunately it’s not just as simple as a top 5 list. You need to assess all the variables surrounding “your” operating conditions and go from there. There is no particular order, that’s the beauty of this game, no rules. I don’t think the “stage 1” exhaust and air cleaner themselves do much, but most folks tune to the rich side after doing the stage 1. So I think it would be more accurate to say tuning rich, rather than stage 1 helps cooling. I think I saw elsewhere that you recently added an oil temp gauge, so obviously now you are “aware” of just how hot she gets. Is your concern primarily for the health of your motor or rider comfort, because that will dictate the direction you take? Anything you do to cool your motor has second and third order effects and considerations. Here is my list of things to reduce heat in no particular order; tuning/fuel enrichment, oil cooling, fan assisted oil cooling, fan assisted air cooling, scoop/ducting, diamond cut heads/jugs, engine internal ceramic coatings, friction reduction coatings, exhaust wrap/coating, under seat insulation, oil type/brand, cams, additional oil capacity, oil pump, gearing, riding style, mid-frame deflectors, tighter squish band. I may have missed some but I’m in a hurry, any of these will reduce heat. You only have to decide which ones you can afford, tolerate the appearance, accept limitations of alternate accessories in conjunction, or any other associated considerations. Bang for buck and appearance, I favor the Jagg 10 row low-mount. Define your specific cooling goals then look for a suitable solution.

+1 on Fuelmoto, I have a PCV and it made a big difference heat wise, well not the PCV itself but the richer map I run with it.
LOL, we have another who thinks a 49 state '09 has a catalytic converter.
Badknees, your limited came with a cooler....the standard ultras do not and still don't.
Sandcrab, the reason the new bikes run so hot is because of the lean A/F ratio to make EPA mandates. Most remedies posted, such a oil coolers, fans, vents, etc, deal with the effects of that, not the reason it's running hot. Deal with the A/F ratio first, and the bike will cool down dramatically, and you may find you don't need the other items.
Also, free flowing air cleaners will make the bike run even leaner, not richer, but the factory Engine Management system on your bike will adjust the mixture automatically back to the stock settings, so again, the A/F ratio is what you logically have to deal with first.
