"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.

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:
 new extended screws
 new springs
 new washers
 new o-rings

$139.95

2.

A Special ZRXOA 2.0 Kit designed for user who wants to use a K&N air filter AND remove the stock airbox snorkel. Why a different kit? Because, when you remove the snorkel and install the K&N or BMC stock replacement air filter, the best needle profile is no longer the same as the above #1.0 or the #3.0 kit, but requires a different needle taper for optimum performance.
Why does dj supply the same needle profile for everything? We don't know, but, we care more about proper tuning over sales dollars.....
Celmat 30 needles and alloy steel allen float bowl screws, a drop-in kit, also. No slide drilling.

Need snappier shifting with fewer missed shifts?
Our Pro Transmission Detent Arm Kit includes Factory Pro Microbearing Detent Arm, firmer 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 quicker, so the gears are more likely to engage under quick shift conditions. The Microbearing removes friction for the quickest shifting.

Tools : diagnostic and setting  

TL-float height gauge

Just wanted to thank you for the quality of your work. I have the Factory Pro Jet kit, K&N stock replacement air filter, and Yoshimura slip-on. Your recommendations were right on. Bike has perfect throttle response. Thanks again.

00'Green.
D&D full exhaust, with alum. canister.
Factory Pro Config 10,100 mains, needles in third notch with one washer under clip .
Mixture screws out 2 2/3 turns. (yeah, yeah. I know, but that's where they ended up when right.)
K&N replacement filter.
Gutted Snorkel and trimmed back 1/2".
Smooth, seamless power delivery from idle to past redline and much "stouter" than stock.

Just a quick note to tell you what a fine job you do on R&D. I just installed a ti kit in my 99 ZRX (Kerker slip-on, K&N filter, foam removed from snorkel throat, and trimmed side cover). 100 mains, e-clip on 3rd slot, and 2.5 turns on mixture screws. Pulls great from idle to redline using your recommended base settings. By the way my other 3 bikes (98 VTR,97 Bandit 1200s, and 94 CB1000)have had the same results with your kits. I never even consider purchasing kits from you know who.

Thanks again for well researched products.

Marc,
I got the 1.0 kit, and I have nothing but good things to say about it.
The directions could not have been easier, and the initial recommendations proved to be so good, I don't think I will mess with it. I have yet to dyno the bike, but it pulls real good, much better than stock.

I also have:
Muzzy megaphone
K&N replacement filter
I have not trimmed the side cover, but I did remove the cage and foam from the snorkel.
If I go with Ted's advancer, will I need to go up to the 102's? ( to help prevent detonation).
Thanks for such a great product.

Question:
A number of ZRX owners (with stock cams and a variety of pipes - not Yosh) have posted dyno results with a pronounced torque dip at about 5000 RPM.
Can you tell us why that happens?

Just wanted to thank you for the quality of your work. I have the Factory Jet kit, K & N stock replacement air filter, and Yoshimura slip-on. Your recommendations were right on. Bike has perfect throttle response. Thanks again.

Answer:
If we check out a bike and change a couple things, perhaps I can shed some light on the subject.

If the torque drops at an rpm during a steady state test (not a sweep test), and the 4 Gas readings indicate a mixture problem, perhaps, by addressing that fuel problem, we could "fix" the torque problem, though, there's not much in a carb that affects only 5k.

It's possible that it is the pipe, possibly aggravated by intake tract length - possibly a few more issues, too.

What is common to all the bikes with torque drop-off problem?
Pipe brand?
jet kit brand?
Stock airbox?
Individual air filters?

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.
