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 - The one you've always wanted!
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!!

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  …
Hi Marc, Just wanted to let you know that your EVO-7 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!

Engine Cover, Billet Alloy

w/ "SKIDzz"
Billet Engine Cover

RH Billet Engine Cover with Steel SKIDzz.
Absolutely the strongest cover you can buy - and has the highest strength / weight ratio available! Exclusive, patented Steel SKIDzz replaceable insert takes the damage!
Hi-Tech flycut surfaces can be polished to a brilliant sheen for the ultimate in show! Does not require a new gasket.
The stock cover grinds through more easily than the Factory Pro cover when "low sided" on the right side of the bike.  If the stock cover breaks, the bike settles even lower and the radiator becomes even more vulnerable to damage.

The only way to accurately measure float heights. Works on nearly every carburetor.


Observations on some test bikes

as delivered, unmodified

pilot jet #12.5 224-103
paj #120 or #125(proto) as delivered .
float heights as delivered bike #1: float heights as delivered: 1&4 = 7.5mm, 2&3 = 8.5mm
bike #2: float heights as delivered: all = 8.5mm
slide damping holes 1ea 3.0mm hole .
main jets 1&4 = #137.5, 2&3 = #140 N102221
maj 1&4 = #75, 2&3 = #60 N102221

Persistent missing at high rpm?  Anti-Theft Alarms?

Regardless of main jet selected? All air correction plumbing is properly connected? - the bike still misses at full throttle / high rpm.

And you have an "alarm" installed???

Disconnect the alarm and retest.

As of October 24, 2001, there have been many reports of alarms causing high rpm misfiring. Disconnect the alarm and the problem goes away.
It can be present when you install the alarm, may start after a crash or sometimes,  just "occur".

Call the alarm company to discuss that with them!

Cheers -

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.
