Was on a nice little backroad a couple of days ago on my ’16 TG when the forward shift peg slipped down when I went to downshift. I couldn’t get my boot toe under the shifter to upshift. Stopped and manually pulled the shifter back up. Don’t recall seeing in the owner’s manual where this behavior is normal. Started back home using the shifter very carefully and deliberately. FYI, I removed the rear shifter when the trike was new.
Went to the local HD shop to get another shifter peg and, for good measure, a new shift shaft. The parts guy said this was normal and folks swap them out all the time. Yup, I know. This was my second shifter swap in 50K. Swapping the shift shaft (try saying that 3 times in a row) and shifter wasn’t rocket surgery and only took about 15 minutes.
The wear on the shifter is obvious on the attached picture. The shift shaft actually looked pretty good but I replaced it anyway.
