My 2013 F6B has a rod only an inch long with no lock nuts and maybe no adjustment.
I just bought some Daytona boots and can barley get my boot tip under the shifter.

I also saw a video from traxtion dynamics showing the above long rod with adjusting nuts. I took my covers off to reveal a short rod only 1 inch with no locking nuts.

Maybe you slide both sides off the bike adjust and slide them back on???????????????

Anyone else with boots have a solution?
