I'll preface this question with some history: I owned a 2006 wing (bought new by me) Installed Kurykyn floorboards rode the wing over 104,000 miles without a problem. Bought a new 2017 wing in March of 17 installed the same footboard (now has 25,000 miles on it, and (after the machine is warmed up) experience the shift sticking when down shifting. I have checked the Kurykyn shifter and there is 'nothing' hanging up the play is free as can be. When the engine is cold (before it warms up) there's no problem. Only after warm up. I use Honda synthetic so there shouldn't be an issue with that.Any suggestions?
