i just installed apex 3" adjustable rise clip ons (55mm).

As far as install difficulty: I started at 730pm and finished at 1130pm. The most difficult thing was getting the new hole for the grips drilled in the proper position. It's helpful to have a second person to hold the grip in place and mark the desired position while you sit on the bike with your hands in the position you want. I did the left bar by myself and over rotated the grip just a bit. The horn is now in the area my thumb naturally moves to for the turn signals. Needless to say, there were at least 2 horn beeps during lane changes on the ride home but it's something i should quickly get used to. These clips ons also require you to drop the forks in order to slide them on, which when the bike is jacked up is actually easier than it thought it would be.
As far as fit and complications: the bars cannot be used to their max rise due to the clutch cable hitting the speedo if you decide to have to riser take off from the front aspect of the fork (option 1 on attached image). If you are ok with rotating the clip on so the riser takes off from the side of the fork you should be able to use all of the rise however the bars will need to be less angled backward or you will hit the tank (option 2 on image).
As far as comfort: these bars are a commitment that is for sure. They are very forward and very low. I have freakishly long arms so the reach does not bother me as much (6'3" 205 37in sleeve). They definitely change the entire feel of the bike from a standard to a full on sport bike. Again I am not using the full amount of rise but I would imagine the riding position to still be very aggressive even with it.
and finally, the look... F$$kin AWESOME. I have CRG folding bar ends on the way and will be sure to post pictures as soon as they are installed. I'd like to thank everyone on the forum for all the information. It helped a lot during the project.
