"Long Boy"
Finger and screwdriver 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:
4 Long Boy fuel screws 
 4 new o-rings
4 new washers
4 new springs

The famous plated "emulsion tubes" (needle jets)
 

Original replacement style

The needle jet orifice can wear oblong in as little as 10,000 miles on 38mm Mikuni's and is particularly aggravated by "in town", low rpm operation. The result is excessive richness at low rpm that can be partially compensated for by lowering the fuel level.
A direct replacement for worn, original items. Accepts standard Mikuni jetting or our Factory Pro Carb Recal Kits.
 Also, can fit Ducati, XTZ750, TDM850, and YZF750.

For the most power, remove the stock airbox and replace it with individual filters.. Use with aftermarket exhaust, makes best maximum power. Low-end and midrange remain good on the YZF1000 without the airbox - when jetted properly.

Cleanable, Dual Style BMC filters feature more surface area than other filters for less intake restriction and up to 2hp additional on the fzr1000 as compared to other cleanable, gauze type filters.
If you have inspected a set of used, non-BMC clamp-on dual inlet air filters, you will likely notice that the inside rubber flange was pulled up and distorted when the clamps were tightened. The BMC filter is spaced more properly for the FZR as compared to other brands of individual air filters and doesn't distort air filter flanges, lessening the chance of allowing unfiltered air to enter the engine.

Pro Transmission Detent Arm Kit

Includes Factory Pro Microbearing Detent Arm, heavy 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 short of an air shifter.
This kit helps prevent  2nd gear missed shifts that FZR1000's are prone to when shifted quickly. Missing 2nd gear under hard acceleration will bend the shift fork - making subsequent shifts into 2nd gear even more inconsistent.
Help prevent  excess shift fork and gear dog wear with this kit.

Float Height Setting Trick for 38mm "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.

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.
