Ken,
Welcome to the site and congrats on the new ride. Which color did you get?
I picked up my 08 SEUC about 2 1/2 weeks ago. I got the Copper Canyon / Silver Mist (or as I see it, Orange & Silver). Anyway, I am loving the bike
. I took it in for the 1K service yesterday. I still have a few mods left to do (pull-back handle bars when they become available, for one).
I had the V&H Big Shot Duals and the SE A/C Back Plate installed before I rode the new bike home. I really like the looks of the new pipes, but they are a little loud for my taste. I have ordered the quite baffles for these pipes and they should be here in a few days. I will report back after I get them installed.
I have not noticed my new bike running any hotter than my 02 Ultra did. I have the HD digital dip-stick and my 08 SEUC is running around 225 degrees. I did see it get up to about 245 degrees in stop & go traffic in 105 degree weather once. Like I said, I had the pipes and A/C back plate installed the day I bought the bike, so I don't know what the temp would have been with the OEM pipes and A/C.
When you change your pipes and A/C, you will have to plan to get a SERT, Power Commander, or the like and then get the bike dyno tuned. This is a must and well worth the investment.
Good luck with the new bike and please post a pic or two when you can.
