You don't have to remove the primary on the 2006 and up Dyna's. The 2006 kit comes with a longer rear shift lever that requires you to remove the primary to install it. That longer shift lever will give you more leverage for an easier shift, but it will also increase your throw. I prefer the shorter throw and it isnt any harder to shift then the original set up. I bought the the cheaper 2005 kit because I planned on getting a custom shift rod. You have to use a longer shift rod with the 2005 kit other wise the front shift lever will hit the primary when you up shift. Also the 2005 kit comes with a bracket to bolt down the original shift lever, but it is pretty easy to remove, read below.
Removing the original shift shaft lever
Get a hacksaw blade and tape each end with duct tape, leaving about two inches exposed in the middle. Also put some duct tape on the primary and cylinder cooling fins. Tape a wrench on one end to get a better grip (on the end of the blade so as you pull on the wrench you will be on the cutting stroke of the blade). Slip the blade between the primary and engine from the bottom of the bike with the wrench end on the bottom. Use your other hand to guide the top of the blade as you cut. I cut about three quarters thru then wrapped a rag around the shift lever and used vise grips on the other end of the shaft splines and sheared it off.
Cover for the original shift shaft lever hole
I used a chrome carriage bolt

Here's a photo with the 2005 kit and a 2006 polished stainless shift rod on my 2006 Low Rider.
