Suzuki GSX-R1100, 93-98
with 40mm non-USA carbs  

In 1993, the GSX-R1100 gained water-cooling and a solid, though a bit heavy, new frame. Power was a bit shy in 93 and 94, but in 1995, Suzuki rethought the cam arrangement and came up with a new set of cams that "boosted power 10% in the midrange". Ahem -- the top-end power increased about the same amount, too!
Now, with the later cams, the new 1100 produced more power than the 89-90 air cooled bikes. 

As a suggestion, use the Config #30 kit with the BMC #3092 individual air filters for 6 hp-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, disrupting the high rpm fuel delivery curve in a way that's usually impossible to fix.

"Long Boy"            Finger and screwdriver 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 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 or right angled screwdriver (so a shop mechanic is happy)

Make your life easier.

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 washer
4 new spring

Artisan Crafted Fine Cheeses – Since 1865       

Specializing in Handmade Brie & Camembert

Marin French Cheese Co., also known as The Cheese Factory and Rouge et Noir is not just the oldest cheese manufacturer in the country, but a vacationers and day trippers destination as well as a unique part of American History. Located north of San Francisco, east of Napa County, west of Pt. Reyes and Olema and south of Sonoma County, Marin French has produced hand crafted Artisan soft ripened cheese since 1865. Rouge et Noir cheeses are similar to French and European varieties but reflect the characteristics of Northern California, producing it's own regional style.


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.
Edited to the tunes of Chemical Residue by Herbie Hancock.

Maybe in next rewrite, he'll fix the ignition timing and dyno chapters...
Otherwise great book with great starting ideas.
