I put on an Add-on heel/toe shifter and couldn't get the bike in fifth gear. The end of the shifter was hitting the bottom of the motor. I cut off the end similar to Kuryakyn's but still miss an occasional shift, plus I had to take off the original shifter's rubber boot or it would occasionally bind with the Add-on's peg when going into the lower gears. I called Add-on Tech support and Alan told me they had encountered about six other Wing owners who have had the same problem. He said it was the way Honda put the shifter on over the "splines". If the shifter was splined several notches higher than "usual", it would do that. He said Add-on is going to put out a replacement in the spring and he would send me a new one. He was very nice, but meanwhile I have to stomp the damn thing to get it to shift. Another problem is that the distance between the heel and toe pedals is about three inches shorter than Kuryakyn's and my boot heel has a tendency to counter my toe shifts because of it! I see no other alternative but to buy a Kuryakyn since the one on my Kuryakyn floorboards shifted very well. I took the floorboards off and replaced them with Mini-floorboards and an offset peg extension that lowers them but can't rob the shifter because of the way it is consctructed. Anyone else had this problem?
