I just installed the Kartboy shifter today along with my Corksport Bronzeoil Bushings. I have to say that the shift is about a smooth as it can be. However it is ALOT harder to actually make the shift I have to really put some a## behind it at least alot more than stock. I think that is normal from what I can remember about discussing the short throws, the shorter the throw the harder it is to make the throw. But I just want to be sure and see if anyone else's shift is hard.
Between the Kartboy shifter and Bushings, and the Corksport Bronzeoil bushings it is smooth as hell!
