I'll start by I have a 07 nightrain with a/c and v&h big rad's exhaust.
I just received my new Xied's in the mail. It took about 1/2 hour to instal on the bike. Very easy job. Worst thing was getting my fat hand under the oil tank. I disconnected my fuel pak and checked my plugs. Plugs were white with black on the threaded area. I started the bike and noticed a very slight difference in exhaust. I noticed it did start much better. I dont think it even turned one full rotation and she fired up. I did about 6 miles in 78 deg. weather (with shorts on) When I got home I put my hand on the rear cylinder I could hold my hand there for a few seconds before removing it. I have no popping between gears, for the most part very little popping on high rev. decel. Its better almost totaly gone. Im waiting a couple hundred miles to check the plugs. Very pleased for a hundred bucks.
