Suzuki GSX-R1100, 89-92
 w/ stock 40mm carbs
(air / oil cooled)In 1989, the GSX-R1100 gained a top-end rush that the 87-88's were lacking in. We raced both of them in the WERA Suzuki Cup series - with the '89 still being competitive against the heavier, water-cooled 1993 GSX-Rs up until '93.
Sadly, the '89 was retired at Road Atlanta, where it became shorter, narrower and not as straight as a racebike should be, as it left the track to become an engine donor for a mini-sprint car...
Great bikes -- With the addition of the later GSX-R forks, it's even better!

As a suggestion, use the Config #30 kit with the BMC #2922 individual air filters for 8-10 hp peak increase over a properly jetted bike with a stock airbox.

Hint! - Do not even try to remove the back of the stock airbox and try to make more hp than the open air filter setup - 2 weeks of work says - nope. With the back of the airbox removed, the intake "velocity stacks" are too long, totally disrupting the high rpm fuel delivery curve in a way that's impossible to fix.

"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.Knurled for easy finger adjust for fuel or weather or altitude or highway cruising mileage.
Straight knurled for pushing with a flat bladed screwdriver if your hand doesn't fit.
Screwdriver slotted for if you want to use a short, normal sized or right angled screwdriver (so a shop mechanic is happy).

Make your life easier.

Installation:
Remove old short stock fuel screws, old o-rings, 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".

New fuel screw kit comes with:
4 Long Boy fuel screws
 4 new o-ring
4 new washers
4 new springs

    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.
