Carburetor Tuning Kit - There is only carb kit that works.

CRB-K88-1.7-RK $289.95

1. Choose your shipping method


The ONLY kit in the world that makes added top-end power.
Allows clean on/off throttle use.

on the 00-01 ZX-9R indicates that it has the same high rpm fuel curve problems as the 94-97 ZX-9R and the
95-97 ZX-6R. There is hp to be had at high rpm by correcting the high rpm fuel curve and main jet stagger. This is something that can be easily identified with a 4 Gas, Low Inertia EC997 Eddy Current Dynamometer, but not on a model 250 dyno anything.

This is the ONLY carb kit that WILL eliminate the abrupt on / off throttle "feature" when properly tuned AND allow the tuner to improve high rpm power up to 2%-3%, without hurting low-end and midrange power.
 If anybody says that somebody else's jet kit works as well, then 99% probability, they've never used this kit.

This kit includes pilots, mains, Factory Pro's emulsion tubes, drills, m.a.j. mod tools, allen screws, simple instruction and took almost 4 months to produce. Enjoy! Marc

PS: This is the kit that is used by the infamous Zlock Bros Racing - rider: Michael Barnes - the team that made more true horsepower than they needed to win!

EVO Shift STAR kit

Slightly stronger detent spring - a new MicroBearing detent arm and the final piece... A completely redesigned, empirically refined, multi angled, variable radii, repeaked and valleyed:
This kit will totally change the feel of the bike as a whole.

Perfect for track use and road riding for effortless downshifts into a corner and just a "tap" to upshift without any more than a "twitch" of the throttle -
Virtually eliminates Missed Shifts.

In town? Low rpm cruise in second - shift to third? So quick and smooth

NO more clunky, lazy shifting in town -  totally different and improved -

Proven concept - Virtually all the Factory Pro Support riders in the AMA and WERA multi- Champions Vesrah Racing tested and proved the EVO-7 Stars .
Stock shift performance that everybody used to take as a "given" will be regarded as "slow and lazy" after riding a zx9 with this kit -
Kit includes a new detent arm with a low friction microbearing roller, a performance shift spring and the NEW Factory Pro EVO Detent Star.
Make shifting MUCH quicker and virtually eliminate missed shifts.

Just remove countershaft sprocket, water pump and shift mechanism cover.

I'm writing this e-mail to let you know how pleased I am with the CRB-K88-1.7-RK race jet kit for my 2000 ZX-9R. I have been synchronizing my carbs at least every other week trying to get rid of the cruise surge.
After talking with you on the phone, the kit sounded like the answer. I am a mountain rider and can care less about 10K+ RPM figures, all my kneedragging is done around 6K, right where the ZX-9R is known to have a throttle glitch, my engine is stock, my pipe is stock and so is my intake and air cleaner. I like the way it sounds, (QUIET) So for all the ZX-9R owners who don't want to change out the aforementioned parts, this kit is the answer.

Here are my final settings;

The air injection was removed and a 4 inch piece of 1/2 inch copper pipe was used between the fittings on the valve cover.

I used the #40 pilot jets you supplied, #170 main jets on 1 & 4 and #172 main jets on 2 & 3. I fashioned a float gauge from some heavy paper board to straddle the carb and ensure a perfect setting of 4mm.

I used a "PIN VISE" from the local hobby shop to drill out the air jets, by the way, your tip on putting a dab of grease on the drill bit to catch the shavings worked great, I just kept on, a few turns at a time and kept wiping off the drill tip after a few turns, till I punched through, no problem.

I then blasted the whole thing with carb cleaner to be sure it was clean.

I tried a few different settings on the mixture screws, the best is 1.5 turns out on all four carbs, all signs of surge are gone, and the bike is so smooth it's almost like having a new one.

I hope you will post this on your feedback to help other ZX-9R owners solve what Kawasaki failed to do right in the first place.

Thanks for producing a product that WORKS,

Best of luck to you.

Hey Marc,

Here is my findings on the pre-production kit, #CRB-K88-1.7-RK. Feel free to post for others to use.

First off the bike was a 00' California model.
Second, this kit WORKED!

We used our (dxxxxxt) dyno for before and after dyno runs.

All Stock as delivered from Jim Gilbert of Ashland, Oregon with 1,390 miles.

Peak hp was 131.6 dynojet hp The bike is fairly "flat" from @8,500~11,500. Resembles a table almost. Customer complained about terrible "lean surge" at cruising and low speeds when he brought it in.

We then proceeded to remove the stock exhaust and
install a new Akrapovic full system. Complete stainless steel with a
carbon fiber canister (20") installed.

First off we removed ALL emission related items; hoses, vent lines, canisters, etc. After that we moved on to removing the
carbs, fairly simple, just be sure to take time in removing throttle cables. (place clean rag over manifolds!) The next
step was to "by pass" the "exhaust air injection system" This is very straight forward. Simply remove the main hose that
comes from the airbox on the right side and goes to the middle of the valve cover (@7" long and 1" dia.) remove the actual
"valve" that connects the previously mentioned hose to two smaller hoses that connect to the valve cover. Next plug off the
vacuum line that is connected to the "valve" and the #3 intake manifold. (we simply remove it and place a vacuum cap over
the #3 intake manifold nipple. finally we install a @4" piece of 1/2" pipe between the two hoses that are still connected
to the valve cover (and used to have the other ends into the "valve") that way the entire system is bypassed. Failure to do
this WILL cause backfire upon deceleration!!
(note: This is a CA bike, but is located in Oregon. It is illegal to tamper with emissions equipment in CA vehicle registered in CA. Marc)

Now onto the carbs.
First off we removed the float bowls on each carb.
Then we replaced each pilot jet (stock #38) with the
provided #40. We then moved onto the emulsion tubes and the main jet (the bigger round one, in center of carb!) We simply
removed the stock emulsion tube with the main jets still installed in them from the carbs. You must then "separate" the
stock emulsion tube from it's OEM "holder", this is very easy just take two 8mm box wrenches. Then install the #emu-188k
factory emulsion tubes into the OEM "holder" and reinstall into carb body. BE SURE NOT TO OVER TIGHTEN the tube. Next we
installed the main jets into our new emulsion tubes. The stock mains were 165 on the outside and 170 inside. We installed
175in and 178out for a starting point. We then checked the float height. Simply "rotate" the carbs until the floats "hang"
free and move freely. Then "roll" the carbs back the other way until the "settle" . DO NOT COMPRESS THE FLOAT VALVE PLUNGER!!! We found this to be right!
t at 4mm as delivered and left this at it current setting. We finally replaced the bowls with the new (and much better)
allen screws provided in the kit.

Next, you must remove the Fuel Mixture Screw plugs. Simply place the carbs so that you are looking straight down on the
bottom of carbs and look for round brass cap (@10mm dia.) and remove with a appropriately sized drill bit. BE CAREFUL!! DO
NOT drill too far! You WILL hit the screw head and mess it up. Take your time. Be sure to clean the carbs off very well
after this. We then turned in each fuel mixture screw until it seats (NOT TOO HARD!) The stock settings were all over the
place from +0x to +2.5x. We set #1 and #4 at +1.25turns out and #2,#3 at +1.5 turns out. This later gave us a CO% reading of
3.5% at idle when bike was fully warmed up.

Next, we moved onto the needles. Once the carb tops were removed the needle retention cap needs to be removed. This is very
simple, just "squeeze" the cap at the arrows and lift up. We removed the stock non-adjustable needles and installed the
#0969j-83o-40v5_2.9bt needles included. The needle clips were placed at the /2 position (from the top) with the stock metal
"shim" RETAINED! Then reverse the order to reinstall the needle, slides and caps. NOTE: if the rubber slide diaphragm does
not want to "stay" in it's groove, try some grease (like Silkolene PRO RG, Dielectric grease or such) in the groove and that should hold it in place while you install the slide top.

Finally we
removed the airbox adapter plate on the back side of the carbs in order to modify the main air jets. When
looking into the back of the carbs you will notice two "jets" you want to drill the MIDDLE ONE!!! Do NOT touch the other.
We used a "PIN VISE" to drill out the main air jets. (A pin vise is a small hand held "drill" that you can purchase from a
hobby shop for  about $9.) TAKE YOUR TIME!! The drill bits are FRAGILE. We enlarged the #1 and #4 M.A.J. to 1.1mm with the BLACK coated drill bit. Then we enlarged the #2 & #3 MAJ's to 1.2mm with the SILVER coated drill bit.

We then, after
making VERY sure the entire carbs were clean, reinstalled then in reverse order of disassembly. Once
installed we warmed the bike up to operating temp and shut off. We then installed a set of mercury carbs sticks and refired
the bike to "synch" the carbs. NOTE: Please do NOT skip this part, carb synch is VERY important for smooth running! And do
not synch until bike is up to operating temp.

After a few moments to warm up we ran a few baseline runs and then "pulled the trigger"

YEEE HAAA! What do you know.... 144.7hp! A HUGE 13+hp gain. Not too bad. More importantly the bike's dyno graph was
actually SMOOTHER than before by A LOT. The bike now peaked at @10,200 and held most of it with in 4% of peak hp at
redline! VERY NICE.

Lastly the moment of truth. A call from Jim on Sunday. He said that he has NEVER in 13years of riding had a bike run so
smoothly and cleanly. The bike warms right up, runs perfectly and has no glitches at any rpm or throttle position!

Thanks again for letting me help your forever ongoing development of the BEST carburetion recalibration kits available. We
at EDR PERFORMANCE will continue to run nothing but FACTORY TUNING products in all our race and street bike. Thanks again,

Hi Marc,
I'm just a backyard tuner, but this kit CRB-K88-1.7-RK for the '00 ZX9 rules!!

Most of the magazines have been complaining about the abrupt throttle response, it cured it, but I was noticing other things too like long warm up times and the bike not starting immediately when hot. (very embarrassing) It cured these things, too! I have a Yoshimura pipe on the bike and until I can get too a dyno, probably next spring, I just installed it as per instructions but I couldn't find anything wrong after riding it most of the day. The installation was sort of easy but I was kind of paranoid about drilling the main air jets having never done that before but it was easy and I blasted carb cleaner all over to make sure the metal shavings were gone.

Also I tried something that I remember you saying once on the CBR list, I hope you weren't kidding cause then I'll feel stupid, that either you or someone that you knew had tried "personal lube" for putting the carb boots back on.
I got a free sample of
Astroglide call (866)TRY-ASTRO through their website and tried it, here's proof, http://www.ptialaska.net/~chrs/astroglide.jpg I swear I have never in my life had carb boots go on so easy it cracked me up.

I am on the ZX mail list and will definitely recommend your products to other listers.


BTW: I went with 175 outer 178 inner mains. needle 2nd pos. with washer. 1 1/2 turns on the mixture screws.

Astroglide! A Slick installation!

Persistent missing at high rpm?  Anti-Theft Alarms?

Regardless of main jet selected? All air correction plumbing is properly connected? - the bike still misses at full throttle / high rpm.

And you have an "alarm" installed???

Disconnect the alarm and retest.

As of October 24, 2001, there have been many reports of alarms causing high rpm misfiring. Disconnect the alarm and the problem goes away.
It can be present when you install the alarm, may start after a crash or sometimes,  just "occur".

Call the alarm company to discuss that with them!

Cheers -

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.
