Factory Pro Carb kit
(without new Factory Pro needle jets or fuel screws)
Standard Premium drop-in carb kit
(carb kit only)
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.
Make float height setting easier! Pick up a Float Cage Holder for Mikuni 38mm carbs - See bottom of this page -
This is the kit that brings back that lowend performance that you lost with that dynojet kit -
New main jet o-rings
Mikuni # 007-790
$5 for 6 orings
New o-rings for Mikuni
"press-in" n208099 main jets.
If you are jetting older carbs, it is a good idea to get new main jet o-rings when buying a carb kit.
|Nickel plated needle jets - Factory Pro|
(replaces 13240041A - Ducati calls it a "needle valve")
(replaces oem duc pn: 13240041A)
Factory Pro design stock replacement Emulsion Tubes / Needle Jets
Replace worn needle jets in stock carbs. 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

Just rode bike awesome shifting, smooth, smooth smooth
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?

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.
|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 $$!!
|When I got back to work,
I set up and made a pile of cute little flat braces.
As I was sitting there, admiring my cleverness...... one of my parts guys wandered by and asked what was I making? I showed him that you could just take my clever little piece of aluminum and hold those float cages right tightly up into their seated position - so you could get consistent float height readings.
It looks like you could just put the float bowl on with the front holes on the bowl lined up with the rear holes on the carb body and slap some screws in and it would do the same thing...........
|I bought him lunch with
the million $$ I didn't make....
Hello. HereÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢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 ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ whereas it didnÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢t before! ThereÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢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 ÃƒÂ¢Ã¢â€šÂ¬Ã…â€œ8ÃƒÂ¢Ã¢â€šÂ¬Ã‚Â on my barcode to be the recommended height on my bike ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ 14mm.
Thanks Mike, for the pics!

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.
Edited to the tunes of Chemical Residue by Herbie Hancock.
Maybe in next rewrite, he'll fix the ignition timing and dyno chapters...
Otherwise great book with great starting ideas.
The little blue bible for quick references and little known facts.
