Suzuki GSX750F Katana, 98-06
Factory Pro Series "S14"

The Factory Pro Carb Recal Kit and the Ignition Advance Rotor will perk up the low-end, add midrange power and response for quicker warm-up and more response. The Transmission Detent Spring Kit really puts "snap" into the shifting and virtually eliminates missed shifts.

Standard drop-in carb kit

The kit, when properly tuned, adds more low-end / midrange and if the proper main jet is selected, more top-end power. Easy to install and tune - no slide drilling required.


CRB-S14-3.0   $139.95


Sorry - the 98 and later 750 Kat is one of the few early bikes that doesn't like the airbox removed - It creates lean spot from 4k to 5k and a rich hump at 7k that can't be fixed with any carb changes -

"Long Boy"
GSX750f finger and screwdriver adjustable extended Fuel Screw assembly

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!

Installation:
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".

Each screw assembly comes with:
4 Long Boy fuel screws  CRZ-SCR-4030m
 4 new o-rings
4 new washers
4 new springs

Ignition Advance Kit

This simple, bolt-on advance kit advances the timing and gives more lowend and midrange -  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 and quicker warm-up. REQUIRES an AIR IMPACT wrench to install.

Northern California's most unforgettable flying experience.  No experience required.  Open weekends!

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.
