"Long Boy"
 VT600c/cd  VLX hand adjustable Fuel Screw assembly

Frustrated with trying to find an "almost 90 degree"  screwdriver with a "D" socket 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".

1 VT600c/VLX screw assembly comes with:
1 Long Boy fuel screw  CRZ-SCR-4010-K
1 new o-ring
1 new washer
1 new 32-spring

Thanks Jason Carmichael of Enterprise, AL for the use of his carb!

The #1 choice for jetting your Honda -
Factory Pro's EC997 dyno developed Carb Recalibration kit.

STD drop-in carb recal kit
Adds more low-end / midrange, if the proper main jet is selected, more top-end power. Easy to install and tune - no slide drilling. Contains 2 needles, a supply of clips, main jets for both carbs.

If you want tuning to Best Power (not fictitious a/f ratio) - for best acceleration and mileage, too, please visit a Factory Pro Tuning Center.
Not just a common "dealership level" dyno!

Pro Shift Kit

Takes 1-2 hours to install.

Makes normal foot shifting much quicker and virtually eliminate missed shifts. Helps address missed shifts caused by poor shift detent "star" profile. Much more consistent shifting.

Helps with quick 1-2 shifts.

This kit will not fix a gearbox with already damaged internal parts. If your transmission is already jumping out of 2nd at full throttle, you waited too long to install this shift improvement kit.

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.
