Boosts power a bit at full throttle,
improves throttle response - especially at low rpm and part throttle,
smoothing power delivery. Engine runs a bit cooler and smoother. No
slide drilling required.
Use with a stock air filter, BMC air filter or Uni or K&N stock replacement
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 quicker, so the gears
are more likely to engage under quick shift conditions. The Microbearing
removes friction for the quickest shifting short of an air shifter.
This kit helps prevent 2nd gear missed shifts that 1000's are
prone to when shifted quickly. Missing 2nd gear under hard acceleration
will bend the shift fork - making subsequent shifts into 2nd gear even
Prevent excess wear with this kit.
Note! SOME pre-production Thunder Aces were equipped with a "flipped around" ball bearinged
detent arm. Not all of them, though. Last time I checked, Yamaha US
was not aware of that and had no documentation indicating that the shift
detent mechanism was any different from the earlier 1000's and 750's.
When I ordered a ThunderAce stock detent arm, I got the same detent
arm as the others. Even did it twice! Same early style arm, twice.
So, what I can say, is that if you have a ball bearinged arm originally,
don't buy this kit - use the SHFT-YAM-4 only. Sorry - that's the best
I can do - Marc

This Carb Recal Kit developed
on the same EC997a Eddy Current dyno that developed the K59-1.7-RK ZX6r RaceKit
(Muzzy and Kinko's choice), the Y73-1.7-RK YZF750 (Vance and Hines choice), S37-1.7-RK
GSXR750, Suzuki of France and most of America's privateer racers choice)...

Marc, I was nice talking with you
this evening (still sitting here with the floats). When you agreed to
receive a picture and some data it made me finally sit down and put this stuff
into print, as opposed to scattered everywhere. As I said the bike has
been a real joy for me. When I bought it as my second bike I still couldn't
ride very well. I was constantly scaring the crud out of myself.
A wonderful friend bought me a gift certificate to the California Superbike
School and that changed everything.
I decided to make a bike that could
out-perform my abilities and as the picture shows I created something special.
When I started to ride it it was crazy how well it handled and made power although
the engine work came later. Every weekend I practiced and then this last
year I decided to race; just for fun. I realized I was pretty competitive.
The bike took a beating but I still love to ride it (yes it's straight) and
people still drop their jaw when they see it, especially after watching it go
through a corner. :)
My last race at Loudon was easy
going until a ZX10 rider got into his groove. The old YZF held it's own
but the power problem I was telling you about caused me to just let him go,
but after the race he was certainly confounded as to why he didn't just leave
me in the dust. That was the best part.
Turns out I did cut the graphics
for the Factory Pro lettering but never put them on, so I sent you a large image
to doctor with Photoshop. I figure you can put the lettering right on
the red side panel (since there isn't anything there). I have a much better
picture at the track but I'll have to scan that in tomorrow.
Thanks for the info on the carbs
and I'm going to cross my fingers. This cliff in performance at low revs
and large throttle makes the bike unrideable. Like I said it feels like
someone has filled a cylinder with water when you open it up.
I'll let you know how everything

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.
