Suzuki gsxr 600
92 - 93
True Rear Wheel HPtm

We competed in the AFM and AMA Pro circuit with the gsxr600.  We shared information with one of the largest teams in the USA. Did you know that if you run .0225" valve to piston clearance, and your AMA rider wings the bike's rpm far beyond the rev limit (it IS possible), that you'll break valves? Well..... such is the way of national class competition.
 We still sell all the AMA parts that we made - shifting, carburetor, ignition advancers and engine cover!

"Long Boy"

Finger adj. extended Fuel Screw Kit

Frustrated with trying to find an "almost 90 degree"  screwdriver to fine adjust your fuel screws for best idle and cruise?
Use Factory Pro's new "finger adjustable" fuel screws to adjust fuel screws for best throttle response. Traveling to high altitude? It's easy to lean out the lowend temporarily.

Make your life easier.

Remove old short stock fuel screws, old orings, old washers and old spring. The o-ring might be stuck in the carb, so, take a light and make sure it's really out if it didn't come out with the screw (or you can't find it after you took out the screw)
Use a small bent wire to pull it out if it doesn't drop out. Keep the old parts for "spares".

Fuel screw assembly comes with:
4 Long Boy fuel screws
 4 new o-ring
4 new washer
4 new spring

"Config 30, C30, Stage 3" style
Config 30 Kit - Remove your airbox for NO top end AND less midrange!!!
We tried - It's one of the very few bikes that make less power without the airbox. There's only a couple bikes with actual tuned airboxes - and none were non-pressurized airbox Japanese bikes - I can't tell you about the pressurized airbox bikes - as there's not much call for removing the production induction systems.

Ignition Advance Kit

This advance rotor advances the timing 2 degrees. With stock engines with stock compression ratios, there is more power everywhere. Part throttle power is better - helping corner exit speeds. Improved in-town drivability.

Transmission Shift Improvement

SHFT-SUZ-4     $49.95

You ever miss second gear? Ouch! - poor bike! Miss it hard once and you bend the shift fork a little bit. Every time you miss that gear, the shift the fork bends a little bit more. Eventually, you will have to replace the 2nd gear fork, the gear that that the fork slides into and the gear that the sliding gear mates to! Bummer.
Prevent missed shifts and damage before it happens.
Make shifting MUCH quicker and virtually eliminate missed shifts. This is the same type of kit that Factory Pro, Honda, Kawasaki, Suzuki and Yamaha Racing has used.

The stock needle jets (incorporated into the top of the emulsion tube on the 36mm Mikuni carb) wear out in as little as 5000 miles of "in town" driving Mikuni carbs, causing excess fuel delivery that cannot be compensated for by lowering the fuel level.
Check out

TL-float height gauge

1. Choose your shipping method



The only way to accurately measure float heights. Works on nearly every carburetor. Float height measurement affects the fuel level in a carb - Fuel level controls the amount of fuel that the carb delivers at low rpm and cruise.

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.
