DescriptionThe whole story▼
The JP ES 044 caps the ZZR1400's KLEEN ports with an aluminium blank on the original fasteners.
Key Features
- Kawasaki ZZR1400 (2006–2023)
- 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
Aluminium Monocoque
Kawasaki built the frame as a single structure over the engine, which is unusual and gave the ZZR its distinctive shape.
Still Quick
A well-maintained ZZR1400 remains faster than almost anything on a public road, and its owners are entirely aware of that.
The Reed Assembly
A moulded housing holding one reed per port, bolted to the cylinder head cover and fed by a hose from the airbox. It is the half that physically admits the air.
What Leaves the Engine
Four items leave the motorcycle: the reed box, the line running forward to the intake, the clips along it and the fasteners underneath. What remains is a cylinder head with a flat cover on it.
Not an Engine Job
Nothing is opened, nothing is drained and nothing internal is disturbed. It is an external component on an external face.
Why This Is Not Urgent
There is no reason to touch a system that still seals. This becomes worth doing when the petals have aged out, or when the motorcycle is being stripped of its road equipment for other reasons entirely.
Doing It With the Head On
Nothing requires the engine to be opened. The housing bolts to an external face and the cover replaces it in the same position.
Sold Separately
Some owners want only the fault gone; others want the whole system out. Kawasaki's arrangement allows both without forcing a choice.
Twenty-Two Litres and Two Hundred Horsepower
The ZZR was built to cover ground at speeds that empty a tank quickly, and everything about its packaging follows from that. The engine bay is dense and anything removed from it is welcome.
