i have a semi-new-to-me 2001 Harley Fatboy. It has a 6 speed tranny, which looks to be an oem housing with no markings on it. Was swapped by a shop prior to me owning it.
The issue now is, when I ride, the bike shifts fine through all 6 gears but while downshifting I push down on the heel/toe shifter and it doesn't do anything. It makes its full motion but doesn't engage to downshift. But if I push forcefully it will engage but might take a time or 3 to go through each gear. And it's become basically impossible to find neutral.


where should I start and how can I narrow this issue down?



thanks!
