After I got my 1800, I brought the kuryakyn brand new. And installed them as per the instruction sheet, using electicial tape, and their enclosed super glue. Both sides because loose, and removal in a very short time. To make a long story short, both grips at different times have become loose at least 3 times each. The last time the right grip became loose, we were on a group ride, and had to make a "temp" repair at a gas station. I had to buy there a small roll of electicial tape, and placed a second "wrapping" of tape, kinda like a barber pole, but the other direction from the first taping. YOU KNOW WHAT. That was some time ago, and to this date, that "temp" repair is still holding, and has not moved what so ever. The left grip became loose again later, and I made that same "temp" repair, and that is still holding just as well!
If anyone else would want to try this, one thing I did find out is for the second wrapping of tape, only go up about 60% of the distance. I found out, on both, that if you go the whole distance, it will cause the rubber area up high to be pushed outwards, properly because it was way too tight. Also remember, no glue of any kind was used in this final repair.
These grips are on a trike, which may be the reason for so glue failures because of extra pressure put on them from the steering force. However the tape, by itself, holds just fine, and I doubt if I will ever need to change anything again. RIDE SAFE.
