DescriptionThe whole story

The JP ES 033 shuts the Z900's air injection opening in the head with a billet cover on an O-ring.

Key Features

  • Kawasaki Z900 (2017–2026)
  • Blanks the secondary air ports in the head
  • Machined from solid aluminium
  • O-ring sealed, no jointing compound
  • Original fastener positions
  • Standard housing refits at any time

Sugomi at Its Most Extreme

The Z900's stance and angles are the fullest expression of Kawasaki's design language. It looks like nothing else and it always has.

A2 Version Available

Kawasaki offered a restricted variant, which put a genuine inline four within reach of riders on a limited licence. Very few rivals bothered.

Not the Electrical Half

The controller monitors its solenoid regardless of what is bolted to the head, so the circuit still needs its own eliminator to keep the panel clear.

Access

The tank and frequently the airbox come off to reach the housing, which is why this belongs in the same session as the electrical half or any other work under there.

Not an Engine Job

Nothing is opened, nothing is drained and nothing internal is disturbed. It is an external component on an external face.

The Thermal Argument

A moulded component bolted to a cylinder head sees a temperature range nothing else on the motorcycle experiences. Aluminium is indifferent to it, which is the entire practical case.

Nothing Hidden

The cover is visible to anybody who looks at the engine, which is the correct way for a change of this kind to work.

An Inspection Would See

Original fasteners in original positions, an unmarked sealing face and a cover that comes off in minutes. Nothing about it is permanent or hidden.

The Value Choice in the Class

Kawasaki has consistently undercut its four-cylinder rivals with the Z900 while giving away very little, which is why so many exist and why the aftermarket for the model is so thoroughly developed.
