Let Factory Pro replace your worn "non-replaceable" needle jets and convert your
carbs into HDJ (High Dispersement Jet) style needle jet carbs.
Better throttle response - potentially better mileage - 2% to 5% more power
- augmented part throttle response.
UK Feedback July 2014
Hi Marc just to let u know I
finally got carbs from UK customs on Wednesday 23rd they sat on them for 10 days
then had the cheek to charge me 70.00 pounds import duty bloody UK - any way,
when I put the carbs back on bike it started first time and bike now goes so
much better thank you and your team for their work very pleased and it now idles
which it had never done before. Thank you very much.
It's just much better the whole way through the rev range but especially higher
revs - just really impressed - thank you.

I only wish that we had the HDJ needle jets when we were racing them back in the
mid to late 90's with Team Kinkos and Muzzy's.
I'd estimate 4 to 6 hp gain on top.
Lowend and midrange are improved by about the same percentage.

HDJ needle jet Installation
"The new needle jets you installed fixed the problem created by the worn out
stock ones.
Before, I could see the large drops (globs) of fuel being released between the
needle and jet while it was idling (air box off).
Now I see nothing."

Best "drop-in" kit. Boosts power a bit
at full throttle, improves throttle response and wheelie ability. Definitely
pulls harder out of 2nd and 3rd gear corners. Pulls
Finely honed to perfection - the Low Inertia EC997 Eddy Current allows
us to discern even the difference between individual cylinders main
jet requirements - unlike lesser dynes!
This is the only brand of carb kit made that can
run smoothly below 3000 rpm on the zx7r. The dynojet kit doesn't -
(and it can't ever).
This is the one carb kit made that contains different emulsion tubes instead of different needles. The problem
with about 80% of the 750's is that they are normally on the lean
side at low rpm and the emulsion tube needs to be changed and then
the stock needles work well, even with no shimming (WITH the
different Factory Pro emulsion tubes.
This kit was also available from Muzzy's.
Note that we said "80%" of the
zx7r's.....
About 20% of the zx7r's are "different".
Those are usually the "7r's" that were too rich, even when all stock.
On THOSE bikes....... we suggest to install the carb kit and follow
the kit float height settings. If that's too rich and stumbly at low
rpm and you DID(!) properly set the float height, then, lean out the
float 1mm to try to lean the lowend.
If that's still too rich, call us or email us. Your 7r needs "leaner than stock" needles
- parts at $60 additional cost + shipping.
That's the solution for the often
perplexing zx7r. It's not perplexing if you know that there's "2
different bikes".

$99.95
inc 4 screws, 4 springs, 4 washers,4 o-rings
|
zx7r 96-03
contains 4 extended screws, springs, washers and
o-rings
"Long
Boy" Fuel Screw
Finger adjustable.
Easily adjust to fix lean decel
backfiring or rich burble - or lean out the cruise for
better highway mileage.
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 screw to adjust fuel
screw 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 screw, old o-ring, old washer 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 Factory
Pro finger adjustable fuel screw kit comes with:
4 Long Boy fuel screw
4 new o-ring
4 new washer
4 new spring
