"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 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

Config 30 carb kit

1100cc / 38mm "750" carb conversion

Have a set of 90-92,  38mm  GSX-R750 carbs? Want to run them on the 1100/1200? Use this 3.0 kit and matching 2922 BMC or K&N air filters.
Note: When procuring 750 carbs, make sure that you get carbs from an air cooled 750. The carb spacing is different on the water cooled 750's.
Note! When replacing a dj kit with Factory Pro components, be sure to replace the emulsion tubes with stock, Suzuki tubes (available from Suzuki). The dynojet emulsion tubes will not work with Suzuki or Factory Pro needles. The Mikuni emulsion tubes have ID numbers and the dynojet tubes are not marked with any part number.

It's possible that the water cooled 750 carbs will fit onto the air cooled 1100 and 1200 engines. You need to use an additional set of 1100
"inside" intake rubbers and put them on the outside cylinders. This is just something that someone told me - I would try with your 2-3 stacks mounted on 1-4 cylinders first.

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.
