STD drop-in carb recal kit

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.
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 needle jets (also called 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 needle jets / emulsion tubes.
This kit is 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 "7'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. With proof of purchase, we will send out a set of "leaner than stock" needles.

That's the solution for the often perplexing zx7r. It's not perplexing if you know that there's "2 different bikes).

Carb Recalibration Kit
CRB-BM06-1.1-TI
Ti ProKit carb recal kit desc.
$89.95 USD
Boosts power at full throttle, even when used with a stock exhaust system. Improves throttle response and wheelie ability. Definitely pulls harder out of 2nd and 3rd gear corners. A should do for maximum performance with or without an aftermarket exhaust slip-on or system.
Snappier engine response throughout the rpm range.

The first test was done using a stock airbox, air filter, intake restrictors and the stock exhaust system - to show what just the Factory Pro Carb Recal Kit will do - all by itself.
Power at high rpm will be improved as much as the low and midrange was improved if you add a freer flowing exhaust system. Additionally, for the inveterate tinkerers, there's a bit more power to be had by opening up the airbox inlet restriction - it'll just take a bit of juggling with larger main jets!

Artisan Crafted Fine Cheeses - Since 1865       

Specializing in Handmade Brie & Camembert

Marin French Cheese Co., also known as The Cheese Factory and Rouge et Noir is not just the oldest cheese manufacturer in the country, but a vacationers and day trippers destination as well as a unique part of American History. Located north of San Francisco, east of Napa County, west of Pt. Reyes and Olema and south of Sonoma County, Marin French has produced hand crafted Artisan soft ripened cheese since 1865. Rouge et Noir cheeses are similar to French and European varieties but reflect the characteristics of Northern California, producing it's own regional style.
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.
