I don't have have but 1100 miles on my Jester, but I had the pipes, mufflers, AC, and SERT put on right out of the dealership. They base mapped the SERT with the 84 map and am waiting to get back home to pick it up from the dealership after having the 1K and dyno done on it. My rear jug label never changed color, like a lot that I've read in here that kept the stock head pipes did, and the bike, according to my digital temp guage says it runs right around 220...except when I get into heavy traffic and then it's gotten up to around 255. I think getting the bike out of that factory lean mode helped mine immediately, plus letting it breathe more like it wants to, helped a lot. I have the 7 year warranty on my bike and my dealer is covering it because I had the mods done by them, so because of that, like Hoist, if I have a major failure on the road and the dealer claims foul on the warranty because of my mods, I'll trailer it up and take it home to my dealer and they'll fix it. Now internal mods may be different, but then again, if I get 90+ hp and 105+ torque after it's been dyno'd with the limited mods I've done, I'll be happier than a pig in mud, which I am now as it is. Compared to my 02 Ultra, the 07 smokes!!!!!!!!!!!! Knock on wood, I've had no problems other than the seal between the inner and outter fairing had to be replaced.
