Well I finally got to ride it this weekend with
the new shift star, and wow what a difference it makes. I refuse to
believe that some time on a grinder with the stock star could make
shifting as nice as this piece. I couldn't miss shift if I tried
with this thing. It hit every gear every time. and it did it
retarded fast, I would say that in one day alone my shifts got 25%
faster, and I know that I could get even more efficient. This shift
star also got rid of some of the clunky feeling of the stock
shifter. The stock one used to feel like it would catch and then
clunk into gear, this one just slips right in, I would say that it
is worth the investment 100%!!  F-Pro EVO Shift Star Makes shifting more positive. The Shift Star has uniquely shaped peaks and valleys for the quickest shifting. Suggest installing a new stock Yamaha shift spring when installing new Arm and Star. It's the F-Pro engine builders secret. |
