Needle jet - 100120K
(also called emulsion tube)

See desc.
needle jet desc

$24ea / $96 set of 4

Factory Pro manufactures replacement needle jets!

(called emulsion tubes by some) to original factory specs.

The needle jet orifice wears oblong in as little as 5,000 - 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 main jets and our Factory Pro Carb Recal Kits.
 Also, Ducati, XTZ750, TDM850, and YZF750.



CRB-Y06-1.0   $129.95

STD drop-in carb recal kit

Boosts power a bit at full throttle, improves throttle response - especially at low rpm and part throttle, smoothing power delivery. Engine runs a bit cooler and smoother. No slide drilling required.
Use with a stock air filter, BMC air filter or Uni or K&N stock replacement air

 
CRB-Y06-1.1-TI    $149.95

Ti ProKit

The same as 1.0 kit, but with Titanium needles and stainless screws, drop-in kit.


CRB-Y06-3.0

$129.95 w/o filters

Config 30 Carb Recal Kit

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.


FI-BMC-#3092
air filter set for #3.0 kit
$124.95
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.
FYI: BMC-3092 specs:
61mm carb bellmouth OD, 25mm between carbs, 85mm center to center dist.

 Cam Sprockets

$59.95 set for 2 cams

 

Adjustable Cam Sprockets for serious tuners and serious home builders.
One set of 2 pcs for each bike.


SHFT-PRO-YAM-4  $89.95

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.
Prevent excess wear with this kit.



SHFT-YAM-4  $39.95

STD transmission detent spring kit

Includes 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. Especially helpful in decreasing the 2nd gear and shift fork wear that the FZR1000's are known for.

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.

-Mike Beary

Thanks Mike, for the pics!
