Heat Issue Help!!!!
Using Jackpot 2-1-2 ceramic with 4" Jackpot "normal" baffles. Didn't get the Jackpot cross-over pipe, but am thinking about it. Have the latest SE Professional Race Tuner with the latest software and maps downloaded from the Mothership. My lowers are installed and it's hotter than hell here, in Arizona.
My bike is 1000% (not hundred, but thousand) cooler with this set-up. By that I mean, only a small fraction of the heat that was evident on the stock bike remains. The remaining heat feels like normal cooling fin exchange to atmosphere to me. There is no hot spot evident on the exhaust system (with possible exception of cross-over pipe area below the bike). There is no cooling noise (tinking, plinking, ringing, popping) when the bike is shut off after a long ride in 105 degree weather. This says to me that the engine is running much cooler than stock. I've actually never had an H-D injected bike that has run this cool. (I believe those headers really flow well)
I started with the "Stage I, 103" race exhaust (whatever that means) and SE high flow air cleaner" MAP from H-D. Upon first flash -- in preparation for Smart Tune -- the MAP was very lean. It exhibited popping on decel, surging at cruise, and lots of heat. Here's where Fuel Moto could, and should, have been more helpful. At any rate, the best starting map from H-D was pretty far from the mark and way-lean.
After two smart tune sessions (on the road), the bike has no surging, no popping, and runs as cool as any air cooled bike possibly can. The tune isn't perfect, but it is very, very close. Heat all but gone.
Your dyno tuner doesn't know what he's doing. You could/should (IMHO) run a Smart Tune on top of the flash that's currently in your bike. I wouldn't go back to the same tuner you've been using, that's for sure. In other words, your bike is running too lean if you're still having heat problems with that set-up after tuning.
(p.s., I do have a sense that the restriction in the stock cross-over pipe is making the whole area under the trans -- and the trans itself -- hotter than necessary. I'm considering adding the Jackpot large diameter cross-over pipe to my set-up. Or, I may wrap the cross over. I'm concerned about the temperature inside the trans. This is my first bike with the new frame, and I'm not used to the temperatures I'm experiencing in the transmission lubricant)
(P.P.S., you either have ceramic coated 2-1-2 header, or you have a Stainless 2-1-2 header. The ceramic header from FM is mild steel, not stainless. And, the stainless headers are not coated)

I also don't recall this much heat with the stock headers... either.... maybe the cat was a big heat sink....
Let me know if you find out anything and I'll post results after I get the exhaust wrapped.
