"Long Boy"
 Finger adjustable and screwdriver 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.

Installation:
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:
2  Long Boy fuel screw  CRZ-SCR-3518k2
2  new o-ring
2 new washer
2 new spring

 

              

Carb Recalibration Kits

CRB-K25-1.0  
$89.95

1. Choose your shipping method

2.

Boosts power at low rpm - helps with surging and if you fine tune and pick the best main jet, will improve pull -
Improves throttle response and wheelie ability (errr.... "potential"). Definitely pulls harder out of 2nd and 3rd gear corners!

Factory Pro's carb kits are the generally accepted primary choice of most experienced users and more experienced tuners.

 
CRB-K25-3.0  
$89.95

So!!!
You took off the airbox and are using K&N filters and the bike won't run......
Get this kit.  :-)

Doesn't include filters (because you already have them......)    :-)

Tools


TL-float height
gauge    
$59.95

1. Choose your shipping method

2.

The only way to accurately measure float heights. Works on nearly every carburetor.

Float height is what you adjust to control your lower rpm operation.



Persistent missing at high rpm?  Anti-Theft Alarms?

Regardless of main jet selected? All air correction plumbing is properly connected? - the bike still misses at full throttle / high rpm.

And you have an "alarm" installed???

Disconnect the alarm and retest.

As of October 24, 2001, there have been many reports of alarms causing high rpm misfiring. Disconnect the alarm and the problem goes away.
It can be present when you install the alarm, may start after a crash or sometimes,  just "occur".

Call the alarm company to discuss that with them!

Cheers -

Marc

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.
