Suggest it is a good idea for whatever future reason you may need to remove the fishtails. Especially on the right side on my bike. The rubber grommets on mine had dried somewhat and I had a devil of a time once the circlip was loosened; trying to pull the 2 fishtail male thingamajiggies out of their respective rubber grommet brackets! I finally squirted some PB Blaster, let it soak into the grommets for a couple of hours. Then clean and lube and reassemble. Tighten circlip to 18 ft.lbs. Might save some time and frustration in the future if a need occurred.
