"Long Boy"
 Extended Fuel Screws

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

CRB-CG07-1.1-TI
(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 -

If you are jetting older carbs, it is a good idea to get new main jet o-rings when buying a carb kit.

CRZ-EMU-100120M/K
Factory Pro design stock replacement Emulsion Tubes

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



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?

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!

Artisan Crafted Fine Cheeses – Since 1865       

Specializing in Handmade Brie & Camembert
Marin French Cheese Co., also known as The Cheese Factory and Rouge et Noir is not just the oldest cheese manufacturer in the country, but a vacationers and day trippers destination as well as a unique part of American History. Located north of San Francisco, east of Napa County, west of Pt. Reyes and Olema and south of Sonoma County, Marin French has produced hand crafted Artisan soft ripened cheese since 1865. Rouge et Noir cheeses are similar to French and European varieties but reflect the characteristics of Northern California, producing it's own regional style.


 
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.
