"Long Boy"
Finger and screwdriver adjustable extended Fuel Screw

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.

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".

Each screw assembly comes with:
4 Long Boy fuel screws 
 4 new o-rings
4 new washers
4 new springs

Transmission Detent Arm Kit

NOTE!!!

 

If you are interested in a Pro Shift kit, we will need the xjr part numbers for the original Yamaha parts to see if we can cross reference them to our model shift kit -

Now that you've replaced the 2nd gear, it's mate and it's shift fork - Install this kit to make 2nd gear stay alive for years. Oh - nicer shifting, too.

Includes: Factory Pro Microbearing Detent Arm, Heavy duty detent spring and gasket. Makes shifting more positive at the expense of slightly stiffer shift lever action. The stronger detent spring rotates the shift drum faster, so the gears are more likely to engage under quick shift conditions. The Microbearing eliminates much friction, allowing the shift drum to rotate quicker for fewer missed shifts. Especially helpful in decreasing the 2nd gear and shift fork wear that the FJ1100's, FJ1200's and other bikes with large, heavy transmission gears are so well known for.
This kit fits both FJ1100 and FJ1200.

Tech Tidbits

 

Float Height Measuring

"touching, but not compressing the float valve spring"

Needle Jet wear
(sometimes called "worn emulsion tubes)
Inspect your brass needle jets for wear when you take out the needles. If the needle jets have oval wear pattern, they will allow excess fuel to pass by the needle causing excess low speed richness.
The fuel will also consist of more, large drops, rather than small drops. Large drops of fuel tend to drop out of the airflow and not burn.
Check out Tech Section for "Needle Jets, Mikuni, worn"

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.
