Adds more low-end / midrange, if the proper main jet is selected, more top-end power. Easy to install and tune.
I picked up a Factory Pro Jet Kit from www.factorypro.com
They are a little pricey but WELL WORTH IT! My buddy highly recommended them and I do too now.
Im not sure about all kits, but on my YFZ450 it was a little more than a simple jet kit. I had to drill my factory MAJ and add another MAJ (Main Air Jet). It was incredible and comes with everything you need. It uses the same jet sizes as the GYTR kit however you don't need as large of jets because of the MAJ modification.
INCREDIBLE KIT! HIGHLY RECOMMENDED!

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%!!

Make shifting MUCH
quicker and virtually eliminate missed shifts. Helps address
missed shifts caused by poor shift detent "star" profile.
The Factory Pro Shift STAR kit is an awesome upgrade for the Yamaha.
Installation: Slightly more complicated than replacing the clutch basket.
No case splitting required.
Yamaha Shift Star kit worked awesome! Not one missed shift all weekend. Easier to find neutral, too - Which is good because I have to put it in neutral to start it for some reason. Doesn't like to start with the clutch in. With the close ratio tranny, I did a lot of shifting.

|The extension of the laboratory
for engines of the Swiss Federal Institute of Technology was completed
in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940).
He had a successful career in Berlin but returned to Switzerland after
the advent of the Nazis. His architectural style was somewhat similar
to that of Erich Mendelsohn. The staircase of the laboratory is in normal
use but well preserved.
