Zet moxa cautery) is total displacement 903 to which Kawasaki Heavy Industries did the manufacturing sales from 1972 to 1976 It is a motorcycle of cc ..Kawasaki, Z1 (Zettowan), and Z900 (...
The main parameter(North America specification)

* The first year of manufacturing: 1972
* Total length × width × total height: 2200(A European specification is 22
45)× 865 × 1170mm.

o Rear wheel: Drum
* Dry weight: 230kg
* Engine type: Z1E type (four valve parallel cylinders of four air cooling
strokes DOHC2)
* Total emission: 903 Cc
* Boa × stroke: 66 × 66mm
* Compression ratio: 8.5
* Max power: 82 hp/ 8,500 rpm
* Max torque: 7.5 kg-m/ 7,000 rpm

Z1 age

* Z1(August, 1972?Initial type in July, 1973):(In the middle of the model) The execution of the oil leak measures of the central cam chain tunnel.
* Z1A(August, 1973?July, 1974):A change in the engine ignition timing and black painting of the engine are abolished, and the brake shoe remainder amount indicator is newly established in a rear brake.
* Z1B (August, 1974?): It changes with the change of the capacity of the fuel tank and the chain oiler abolition "900" the seal chain adoption and the emblem styles of type.

Z900 age

* Z900-A4 (model in 1976): Front wheel double disk making (Only a European specification :), change in the ignition system, Shaiki change by the antipollution policy, and maximum output/torque → 81 ps/ 7.3kg.

A basic frame (Though the displacement improved) and the engine block are succeeded as it is though Z1000 (-A1) is put on the market in 1977, and a peculiar silhouette to Z1 is lost by two muffler making.

Kawasaki and GPZ900R (Gapezet moxa cautery are) are the motorcycles, and new generation sports Zarah of the Kawasaki (Kawasaki Heavy Industries) marketed in 1984. A pet name of Ninja (ninja) was named to the North America specification.
Outline

Because it was not possible to hope, and weight was too large, the performance gain more than this ruined the movement though GPz1100 that had been manufactured till then adopted four air cooling cylinder engine with the tradition since Z-1.

To achieve loading sports with brilliant under the power performance and the one class of GPz1100 or more, GPZ900R was developed. At that time, the engine demonstrated 115ps by the displacement of 908cc in the first generation of water-cooled designed quite newly, and was a performance of the first class. Moreover, the body that supported it adopted a diamond frame that used the engine as a stress member instead of abolishing the down tube made of high-tension steel (high-tensile steel) assumed to be a RIDGID conclusion without having the mule mount, and contributed to the small size and lightening. Moreover, the adoption of 16-inch wheel will be able to be called a novel point with full Cowling who suppresses the air resistance at that time.

A light sports car more than GPz110 0 was born in all respects such as the speed, acceleration, and cornering though some maximum speed of GPZ900R marked 250Km/h, and was inferior to that of GPz1100 by the horsepower as the result.

"GP z750R" (748cc/77ps･G1-G3) that downed the boa stroke exists as a sisters car for the domestic market because it was not able to turn on GPZ900R to the domestic market in the relation of the independent restriction to sales of the large displacement car of 750cc or more until 1991.

This engine hit as real water-cooled engine at the first generation has the structure not seen so much in the other companies that doesn't use the stud bolt, and cools the sleeve directly by a wet liner. In addition, the thing to adopt "Side cam chain" method is the feature one in the cam chain because suction is made more straight and it improves efficiency laid out to the left end.

The approval or disapproval comes from there is a dislike of strength and lubrication shortage a little, and burning into first when the output improves of this part of the crank in the place in which it divides though combining ..digging.. and the crank shaft try the waist under by the crank web and assume the suppressed structure with one-place's of the journal cap, and try a primary gear of the first deceleration to control the width of the engine. The RIDGID mount that the mount is done directly by the frame without the mule is scheduled, and it averts and because F measures were necessary, the first balancer driven by the output from the crank shaft is built into at first this engine.

The cylinder head looks very large from the left side the valve scissors corner is might large, large-scale, and with the cam chain tunnel especially when seeing from the present level. The inside of this head is locker arm type DOHC of one cam two valve drive, and "Cageri" is caused easily from defective lubrication, and it is enumerated in one of the weak points between slippers sides of this camshaft and the locker arm.

The point that derived type's engine built one age afterwards from develop the point and afterwards exactly became "Mainspring" abundant might be value to the special mention from which it extends for 20 years to be near afterwards and this cars are produced though it was an engine with a lot of weak points like this.

It is off-the-beaten-path that the racing machine based on this engine was developed in parallel with GPZ900R though Kawasaki was not able to turn on the actual combat because it stopped the race activity in 1983.
Remodeling

It is possible to make it to various seasoning and the displacements by using parts of following model (GPZ1000RX,ZX-10,ZZ-R1 100,GPZ1100,ZRX1100,ZRX1200, ZZ-R1200) etc. as a method of the custom (remodel). Moreover, a camshaft, a piston, a connecting rod, the clutch, and the mission, etc. exist from a manufacturer outside the company, too.
