Needle Jet Replacement - Convert to zx9r Supercarb set










side view HDJ emulsion tube



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 8 hp gain on top -  that would make it def stronger than the later model zx9r!
Lowend and midrange are improved by about the same percentage.

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.

Ignition Advance Rotor. Adds beaucoup power at ALL part throttle positions. That equates to more "snap" in throttle response for you!

This is the famous "1.7-RK RACE KIT"!

Willing to do a bit of carb machining (drill and tap w/ supplied taps)?
What if you could have an additional 4-8 True Rear Wheel HP after 10,000 rpm over ANY OTHER CARB KIT?
Want more power than the 98-99 zx9r??
It took the EC997 Low Inertia Eddy Current dynamometer WITH the Integrated 4 Gas Analyzer to map the fuel curve to develop this kit.
This is far, far superior than a Flo-Commander.

Best "drop-in" carb kit available.

No slide drilling required!
Kaw CARB Float  Valve TECH NOTES: Most Kaws tune well and easily with the Factory Pro kits - however, some Kaws have a problem with low speed operation -
If that's the case, and you've adjusted and reset the float height leaner and 18mm still isn't lean enough at cruise, and especially if the problem is on 1, 2 or 3 cylinders, please inspect the float valves for the dreaded  rubber tip shrinkage.
Some fuel additives attack the float valve rubber tip and cause it to shrink and distort. Now, nobody needs a shrunken, distorted rubber and, being non-round, will allow not shut off fuel in the carbs with the bad float valves and cause very rough low speed running (as the fuel level keeps rising in the carb bowl).
It's not a "common problem", but if the normal tuning stuff doesn't work...........
Thanks for the tip from Mikee at Seaside Superbikes, Seaside, CA 831 760 2701

Pro Shift Kit

This is exactly the same kit as we developed for Team Kinko's Kawasaki for the AMA 750 Supersport Series.

Make shifting MUCH quicker and virtually eliminate missed shifts when it's done.

This is the exact same kit that Team Kinko's Kawasaki used in their mighty 750 (same in 750 and 900) used in their highly competitive Kawasaki AMA 750 Supersport bike to make shifting quicker and miss fewer shifts.

This kit will not fix a broken transmission ("rounded dogs, bent forks"), but it WILL make the shift selector mechanism get the shift start where it's supposed to be - and on most bikes, them means quicker shift, slicker shifts and fewer missed shifts, including the "1-2" shift.

Absolutely the BEST way to measure float heights.

Measures in MM.

   

This Carb Recal Kit developed on the same EC997a Eddy Current dyno that developed the
K59-1.7-RK ZX-6R
 RaceKit (Muzzy and Kinko's choice), the Y73-1.7-RK YZF750 (Vance and Hines choice), S37-1.7-RK GSXR750,

Hi James -

Glad it runs better -

The way jetting actually works (and fuel injection is the same way), is that each bike is potentially different - and temperatures, barometric pressure and humidity are localized influences on what jetting (or fuel injection mapping) works the best.

1. "Fine tuning" is the process in which you slightly tweak the settings to get the absolute best settings for best performance..
2. "Ok settings" are settings that don't produce any misfiring or surging.
3. "Starting settings" are the settings that we give you that we "hope" are at least "#2"......... They are not "recommended", they are "starting" settings.

Whether the "starting settings" are close enough for most people depends on how well the original kit was designed -
On the EC997 dyne systems, it's actually pretty tough to develop a poor jet kit.
On the dynojet side, their dealership level dynos (all of their dynos) would say that what you had before, was "right".

Moral?
Use EC997 dynos and don't use dynojet dynos.

The bike runs great.  It pulls hard, and has excellent top end.  It does not even feel like same bike.  I will try using the choke very little and see what happens.  I would rather not mess with your recommend settings.  I hope to spend some time with the bike this weekend to try the fine tuning.  I did sync the carb also right before the jet kit, and set the float height to the factory setting according the book. 13mm.  What do you mean by fine tuning?   Thank you for helping.  James

If you want the bike to maybe idle with the choke on, you'll have to turn the fuel screw in.
Try a 1/4, and even more in.

You are balancing good running performance vs. "making the choke work". Your choice.

You haven't really done any tuning. We'd spend 1-3 hours on fine tuning.

You haven't mentioned how the bike ran?

I have not tried any other settings.  I had a dynojet kit in my other zx9r with the pilot 3.5 turns out.  and it would start and run with no choke ever.  Should I turn the pilot back in one half or a quarter turn? 

Marc Salvisberg <factory2@ix.netcom.com> wrote:
You richened up the idle mixture - The choke still thinks it needs to richen enough to work with the "too lean" stock pilot mixture.
The richer pilot circuit mixture + the choke mixture = too rich to "idle high".

You can either lean out the pilot circuit (so it's too lean again) and the choke will idle high, like it used to. Or, (like most everybody else) just start it, then, turn the choke off (as soon as possible) and keep the engine running by hand (which is usual).
I would sit there with the choke on, keeping the engine running > turn the choke off.
You won't hurt the engine by turning the choke off earlier than before;.
Just keep the engine running till it's warm enough to ride safely.

Remember, this is a carbureted bike - not a fuel injected vehicle.

You didn't mention trying any other settings?
Did you?

Thanks -

Hello.
 
I just installed a factory 1.0 jet kit in my 1995 Kawasaki ZX-9R.  I followed all instructions.  I have done this before, and work on my own bikes all of the time.  This time I'm having bad idle problems.  The first night the bike started right up, smooth idle, great cruising, and mid, and top end.  Power is excellent.  But now every time I go to start the bike with choke on it will not idle.  I have to keep reving it up until warm then it idles.  It will puff out some black smoke also.  carbs were stock before jet kit. Thank you for any help you can provide.

The Military Vehicle Technology Foundation was founded by the late Jacques Littlefield. It is located in Portola Valley, just south of San Francisco.

The Military Vehicle Technology Foundation oversees one of the largest and most significant collections of historical military vehicles in the world. Our goal is to acquire, restore, and interpret the historical significance of 20th and 21st century military vehicles. Domestic and foreign combat vehicles such as tanks, armored cars, self-propelled artillery, and other technically interesting mobile platforms are the focus of the collection. We also maintain an extensive technical library that describes many vehicles down to the part level. Aside from the vehicles, there are towed artillery, antitank, and antiaircraft guns. Military support equipment, inert ordnance, and accessories round out the collection.

There are over 200 vehicles in the Foundation's collection, many of them exceedingly rare. The updated site will have greatly increased content and information on the collection, as well as information on how to book tours or arrange access for commercial purposes.     To arrange and schedule a Tour.
 

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.
