Dunlop Test Concludes at Daytona

Reigning AMA Superbike Champion Doug Chandler and 1995 champion Miguel Duhamel were among a list of 14 riders on hand yesterday at Daytona International Speedway for Dunlop's annual pre-Daytona 200 test session. Chandler and Pascal Picotte put their marks on the test early with Chandler recording his quickest-ever lap times on a Superbike and Picotte steadily lowering the mark in the 600 Supersport ranks.

Seven teams took part in the testing with the factory squads from Honda, Kawasaki, Suzuki and Yamaha joined by the the Supersport support teams of Honda, Kawasaki and Yamaha. Two-time Daytona 200 winner Duhamel did time on his 1996 Smokin' Joe's Honda superbike machinery plus 600 Supersport machinery with 1997 pieces.

Chandler was joined by two new teammates -- Tommy Hayden and Todd Harrington -- on the Team Muzzy Kawasaki squad. Hayden spent time on both the Superbike and 600 Supersport machinery while Harrington tested on the Supersport bike. The ZX-6 machines were new with the ZX-7 Superbikes in '96 trim.

Thomas Stevens tested on Monday with the Kinko's Kawasaki 600 Supersport support team,
but spectated the next two days after coming to an agreement to race a Ducati for Vance & Hines in the AMA Superbike Series.

Factory Pro supplied all tuning EC997 dynos and all the carburetor tuning, ignition and shifting items for the ultra quick Scott Beach / Michael Tjon EC997 dyno tuned Kawasakis.

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.
Karl Rouse  UK

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.

Replace worn needle jets - upgrade to  HDJ needle jets. $280

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."

Dear Sir/Madam,

I am just writing to compliment your product that I have recently purchased. I have a Kawasaki ZX7R (P5) and wanted to change the jetting, as I have tried both xxxxxxx kits and xxxx's jet kit and neither of them were successful and resulted in two ruined sets of carbs. However after purchasing your product I found that it was a lot easier to change the jets and made an instant improvement to the overall performance of my motorbike. once again i thank you for producing such high quality and uncomplicated goods. I also would like to thank you for producing products that have sprung my bike back to life.

Many thanks,

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".

EZ Adjust Fuel Screw Set

Extended Fuel Screw Set

zx7r, 96-03


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.

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

Absolutely the BEST way to measure float heights.

 We are in need of a stock-engined (no cams, porting, etc.) 96-97 ZX-7RR to develop a kit for the stock Keihin FCR carbs.

Float bowl pressure MUST ALWAYS equal airbox pressure -
blue arrows

The 2 float bowl vents (1 each between each pair of carbs - total 2 hoses) MUST join together into that black plastic manifold sort of tube and then go  into that ~1/2 / 12mm hose that goes forward as the blue arrows show. The modified setup simplifies hose routing and eliminates one of the "tarantula valves".

Eliminating the "Exhaust Air Injection" system -
red arrows

In order to get consistent, tunable idle and eliminate backfiring under closed throttle deceleration caused by air leaking into exhaust:
1. Join the 2 rubber 90 degree fittings in the valve cover together with a pipe or tube. or
2. Plug the 2 rubber fittings. or
3. Make aluminum covers for the valve cover spigots. or
4. Take the spigots off and make a solid gasket that seals the underside of the spigot and blocks the air. That will make a mechanic really scratch his head later when the bike runs OK and the spigots aren't capped!


Thanks Rozz_ZX7r for the picture!!

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.
