"Long Boy"
 Finger and screwdriver adjustable extended Fuel Screw assembly

Frustrated with trying to find an "almost 90 degree"  screwdriver to fine adjust your fuel screw for best idle and cruise?
Use Factory Pro's new "finger adjustable" fuel screw to adjust fuel screw for best throttle response. Traveling to high altitude? It's easy to lean out the lowend temporarily.

Make your life easier.

Remove old short stock fuel screw, old o-ring, old washer and old spring. The o-ring might be stuck in the carb, so take a light and make sure it's really out  (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".

Screw assembly kit comes with:
 new extended screws
 new springs
 new washers
 new o-rings

talked to a guy who said this spring worked really well. Actually said he cut over a second from his lap times just because he didn't have to worry about missed shifts anymore. He said he told all his friends to get one.

Countless hours of thought went into this spring's specs.

That's it. A carefully fabricated and heat treated spring.

2. Replace old spring with New Blue Shift Spring.

Factory Jet kit for ZR-7

To the Factory Team...

I just wanted to express my gratitude and satisfaction with the jet kit your company has made for the ZR-7.
I have definitely noticed improvement in throttle response and roll-on with this kit. This is how the bike 
SHOULD be from the factory.

I would also like to commend Raul, Erik, and the rest of the team at Factory Pro. They ensured I was getting
a quality product and took the time to tune the bike to its utmost rather than just throw in a kit. I was
very impressed with the professionalism of your staff and the service shown to me. As seen on your website
and in your shops the class of motorcycles your company builds products for, I was pleased that your team
took the time and effort to make such a great product for a motorcycle that is not a track / supersport, but
an all-around real-world motorcycle. I look forward to buying other products that you make for this motor-
cycle and future motorcycles I may own.

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.
