Super stiff shifting after installing bronze shifter bushing

[TheZnewbie]

Hey guys, so i ordered some bronze shifter bushings from Z1. When installing them there was no issues as they just slipped in. However when trying to shift it was super hard to get into any gear and almost felt like it was being held back by something. It went into the gear but it took way too much force. After switching back to the old bushings it felt normal just like before. Anyone else have this issue or a solution for it? I installed it just as it should. The old bushings had 2 plastic pieces with a metal rod going thought it and the bronze ones were just 2 pieces without a center section. Also Im still on the stock shifter. No short shifter.
-thanks!

Don't over tighten the 8mm bolt/nut that goes through the bushing too much, be sure to use a self locking nut.

I had the same problem when I put my bronze bushings in. Just snug the locknut down, it won't go anywhere
