O.K., I have more questions after reading the installation instructions on the link I gave (no PDF of instructions on the Dual Star web site that I could find).
First, it says that if the throttle sleeve has ribs, they will have to be cut or ground off. Do the C14's have ribs? I know my TL1000R did.
Second, it says to use JB Weld or some similar high-temp adhesive to install the grips, did you guys do that or just do the old hair-spray or liquid soap install method?
