I ordered a Shad trunk from Murph and saw the shifter kit for sale. I thought pretty cheap, added it to the order (I think it was $21, don't remember).
My '11 just turned 5000 miles, I figured it couldn't hurt.
Took me about 20 minutes to install. Took it for a spin- wow! Before, the shifting would feel slightly off, don't know how to describe it. It didn't shift poorly to the point where I would think it needed service, just that I thought it shifted like it should. With
the bearings, it shifted much better, felt like brand new, the day I rode it from the dealership.I guess that plastic bushing (piece of Y%^U*!!!) is like shock absorbers-it slowly wears out and you don't realize how bad it is until you replace it.
I don't consider it an upgrade as it didn't make the bike shift better per se, it merely restored the shifting to the level it was at with 1 mile on the odo. I think this part is a must have and if you have over 5k miles on your bike with the plastic stock sleeve, spend $21 to see what you are missing. I think it a bargain to make the bike feel like new again.
