Suzuki GSX600F Katana, 90-92
Factory Pro Series "S02"

The Carb Recal Kit and the Ignition Advance Rotor perks up the low-end and midrange power and response for quicker warm-up and more response. The Transmission Detent Spring Kit really puts "snap" into the shifting.

The 90-92 is just about the same bike as the bike that we used to wins tons of roadraces in 89 with Dave Deveau as the rider.
The carb kit we used? The same Factory Pro Supersport Carb Recalibration kit that you can buy, right here.
The Advancer? The very same RTR-SUZ-4 that you can buy here.
The Shift Kit? Yep - the very same one you can buy here, too -

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.
