"Long Boy"
Finger 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:
2 Long Boy fuel screws 
 2 new o-rings
2 new washers
2 new springs

Adds more low-end / midrange, if the proper main jet is selected, more top-end power. Easy to install and tune -
no slide drilling!
Suggest using a BMC replacement air filter for increased airflow.

you sent me (overnite, thank you very much!) the ducati 900ss kit last month with needle jets (I also sent you the pix of my naked ST with a factory pro jet kit) and jeee-zusss! It may as well be a new bike. Float levels were 2-3mm high and once adjusted and everything installed, the bike was perfect _ started immediately idles smoothly and pulls hard.
The owner used to wear a bandolier of fresh plugs cuz she'd replace em every 80 miles or fewer in the front cyl...your kit (and setting float levels) made a huge diff.

Hi!

I just put on the Ti Pro carb kit and the emulsion tubes on my M900. After spending a few hours finally my bike runs as a really Monster. Having trying other carb kit in the past with no success in performance i need to say thanks for the information on your website and recommend the FACTORY PRO CARB KIT as the ONLY kit that really works and solves problems!

Hi Marc,

Installed the full Perfect Mikuni Ti rebuild kit in our recently acquired 900ss. The bike is a very clean example with only legit 4700 miles on the clock.

—Stock air box
Snorkels in
—KN filter
—Stock header
Remus CF slip-ons (same as Ducati Performance of the day)

Carbs looked like they were brand new when pulled, with some very slight wear to the original needles and tubes and a very poor synch job.

Best (perfect, actually)setup for us in Santa Monica, California:
—130 Main Jet
—40 Pilot Jet
—Needles at position 3
—Vertical Fuel Screw at 3.75 turns out
—Horizontal Fuel Screw at 3.5 turns out

The Duc now pulls clean and hard from 1100 RPM idle straight to redline, with no backfire on decel and plugs that look great. Warm-up is easy, with very little choke needed for just the first 30 seconds or so.

Thank you,
Greg and Noah Pinto

Replace worn bare brass needle jets in stock carbs with Factory Pro's own stock replacement nickel plated needle jets.

The needle, stock or aftermarket, will wear the needle jet orifice oblong - causing excess fuel to flow at cruise and low rpm. Additionally, the fuel that does get released is in larger, less burnable droplets. Replace the emulsion tubes / needle jets if there is more than 10k miles of varied use or 5k miles of in town driving on the bike before trying to tune. You will save time and energy.

Note that, with fuel level adjustments, you can make some mixture adjustments with the "fuel level", as adjusted by "float height" changes.

Lightweight Shift Centering Spring



For when you decide that you want lighter feeling shift lever action for better feel.
A lighter foot shift pressure is less unsettling.
Decreases lever effort required to make a shift.
 Makes foot shift pressure more like other sportbikes.
Since you are not having to push so hard to move the lever, it's easier to find neutral.

Like your rearsets? But, no matter how you lube, shim, adjust the arcs, angles and lengths, it's still annoyingly stiff to shift?

Got your jet kit for my 1997 M900 ducati (stock airbox with full ducati performance exhaust), installed it "drop it" using base settings (middle clip and 145 main jet, 42.5 pilot) using your new plated needle jets and this bike FINALLY runs perfect! I have been fighting with jetting this thing for weeks and is probably why this bike only had 3500 miles on it. Ran like crap at part throttle cruise (missing and stumbling) and weak power unless wide open over 4500 RPM and ran out of juice at 6500. Now it pulls strong everywhere and runs smooth as silk. Thanks again for a great product!

And tell Marc that Stuart Anderson says hey. :-)

My God! It's a miracle!  Bless you, bless you! 
I've been fighting with this damn M900 jetting for nearly three years.  I've had the carburetors on and off and changed the jetting so many times that I could do it in the dark.  I've spent big money to have Ducati "experts" try their hands to no avail.  Even Dynojet, whose stage II kit I've been trying to use, had no solutions.  The general consensus was that this bike simply was not going to run cleanly a low throttle settings.  Crap!  How could this be?  Hell, they're just plain old Mikuni carburetors!  Then I stumbled onto your web site about
worn emulsion tubes.  Praise be!  Your magic little emulsion tubes have cured every thing.  (Well, not everything but at least my Monster jetting troubles).  I now, after all these years, have a great running Ducati Monster.  I am , once again, a happy man.

Thanks,

Thanks for the springs.  Got them last week and installed the jet kit over the weekend along with new exhaust cans...it's like a whole new Monster.   Very impressed overall with the kit and your service.  I'll definitely recommend the kit to my friends.
 
Thanks again.

Float Height Setting Trick for 38 Mik's
One of the problems with setting the float height on the 38mm downdraft Mikuni's that come on Ducati's, yzf 750's, tdm 850's and fzr1000's, is that the darn white plastic "float cage" keeps popping out of the carb body unless you hold it in.

When you hold it in with your fingers, you always flex the cage frame and distort the reading that you are setting the float height at..... Aaarrggghhh!!  :-)

After spending 45 minutes setting some yzf750 carbs in the sweltering Mid Ohio heat of summer, I decided to make a float cage holder and sell 'em! I'd make a million  $$!!

When I got back to work, I set up and made a pile of cute little flat braces.

As I was sitting there, admiring my cleverness...... one of my parts guys wandered by and asked what was I making? I showed him that you could just take my clever little piece of aluminum and hold those float cages right tightly up into their seated position - so you could get consistent float height readings.

He says.....
It looks like you could just put the float bowl on with the front holes on the bowl lined up with the rear holes on the carb body and slap some screws in and it would do the same thing...........
I bought him lunch with the million $$ I didn't make....

Hello.  Here’s the pics you asked for!  Thanks for the help, the bike runs BEAUTIFULLY now, lots more power!  The front end now comes up on the throttle – whereas it didn’t before!  There’s another pic in there too where I used a bar code to measure the bowls.  I found this a lot easier than using a ruler.  I measured the bar next to the number “8” on my barcode to be the recommended height on my bike – 14mm.

-Mike Beary

Thanks Mike, for the pics!

Northern California's most unforgettable flying experience.  No experience required.  Open weekends!

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.
