Dynojet Jet Kit STAGE 1 for Kawasaki ZX-9R 02-03

Dynojet kits provide a simple solution to carburetion problems, increase power and improve delivery. Dynojet offers a wide range of carburetor calibration kits for every type of application. Based on pins with a profile different from the original, and accompanied by other assorted material depending on the type of motorcycle (jets, springs, air correctors, etc.), the kits are divided into different types - or "stages".

The type of STAGE is indicated in the product title

STAGE KIT 1
These kits are designed for motorcycles with original engine and airbox. The kits include all the material and instructions necessary to be mounted with the standard exhaust and filter or with a more open air filter and free exhaust. The stage 1 kits improve engine response and delivery, and increase power across the entire delivery curve by approximately 5%.

STAGE 2 KIT
Designed for motorcycles with standard or lightly prepared engines with modified airbox. The kits include all the material and instructions necessary to be mounted with exhaust and with a more open air filter and free exhaust. The stage 2 kits are designed for motorcycles where it is not possible to mount individual filters directly on the carburettors and for motorcycles on which modifications to the airbox improve engine performance. In most cases they allow power increases of up to 8%.

STAGE 3 KIT
Designed for motorcycles with a standard or lightly prepared engine with the elimination of the airbox and the installation of single filters; to be combined preferably with a good open exhaust. They allow power increases of up to 10-15%. They can cause less linear power delivery than the original on short-stroke, high-rpm engines. They are mainly available for traditional motorbikes, as on motorbikes with more recent engines and airboxes, the installation of single filters does not allow increases in power and can compromise power delivery.

STAGE 7 KIT
Designed for competitive use only or for special applications, such as the complete kit for V-Max. On the most recent sports bikes they have been replaced in the Dynojet range by stage 1 kits with the addition of some specific advice for competition calibrations.
