Kawasaki ZX-6R, 95-97
All power products developed and tested on the Low Inertia EC997 Eddy Current Dynamometer

Factory Pro was instrumental in developing Robert Nutt's Team Kinkos / Scott Beach carburetion kits for their zx6r and zx7rs. By the end of 95, every AMA team, including Muzzy's and  except for one Canadian team had switched to the Factory Pro  "1.7-RK"   RaceKit carb kit. The "1.7-RK" kit is the only kit that fixes all the things that were needed in the carb for best lowend, midrange and topend.
The kit was worth 2-3 True HP at high rpm.

1.7 Race Kit


Slightly more complex than a std jet kit to install. If you want the best, smoothest, power at ALL rpms, this IS the BEST kit.
Use with stock or aftermarket exhaust, makes best power, overall. Period.

It took me 6 weeks of fiddling to make this bike sing. Learned a lot.

Actually, this is the ONLY kit we sell. It works better than any other jet kit.

EVO Shift STAR Kit

Includes Factory's AWESOME Detent Star - Totally changes the rough shifting the Kaw 6's are known for into the sweetest shifting Kaw.
Includes: Factory Pro designed, refined and manufactured DETENT STAR, Factory Pro Microbearing Detent Arm, heavy duty detent spring and gasket. Makes shifting quicker and more positive - "virtually" eliminating those nasty missed shifts. The stronger detent spring rotates the shift drum quicker, so the gears are more likely to engage under quick shift conditions - and "lazy" ones, too -
The Factory Pro Microbearing removes friction for the quickest shifting.
The closest to a "paddle shifter" for a motorcycle that you will ever find!!#1 best shift improvement
Hi Marc,
I hope you are doing well. I am curious if you would be able to help me out on a couple of products, for an SV650. I am looking for the EVO Shift kit, part # SHFT-EVO-S36-KT, and the 90149-08094-00 Adjustable Center Shift Stud. It is for a race bike, and I will be happy to run your stickers and tell everyone how cool you guys are. And how cool the kit is, I have one on my old '01 ZX6R race bike and it was one of the best things I did to that bike.
Thanks a lot for your time.

Positive feedback rating    Oh, the shift star works great.  I mean the Kawis have always been a bear to shift.  And the EVO cleared that up.  Love it -
Thanks -  Douglas  Isham  …

 Positive feedback rating       Hi Marc, Just wanted to let you know that your EVO Shift Star Kit ROCKS! I've been having problems getting a lot of missed shifts between 3 & 4th gears in my 636 and after installing your kit, the problem is 100% GONE. I raced out at Streets of Willow this past weekend and didn't have one single missed shift anywhere and the positive engagement feel is perfect. Thanks for making my 636 an even better bike!

Pro Transmission Detent Arm Kit

Includes Factory Pro Microbearing Detent Arm, heavy duty detent spring and gasket. Makes shifting more positive at the expense of slightly stiffer shift lever action. The stronger detent spring rotates the shift drum faster, so the gears are more likely to engage under quick shift conditions. The Microbearing removes friction for the quickest 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.
