DescriptionThe whole story▼
The JP ES 033 seals the Z1100's KLEEN ports in the cylinder head with a machined blank.
Key Features
- Kawasaki Z1100 (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
A Colour Dashboard
Full connectivity and a legible layout, which the Z1000 never had and which buyers at this price now expect as standard.
Cornering ABS
A six-axis platform feeding lean-sensitive braking and traction. It is the electronics package the previous naked four never received.
Original Fastener Positions
The cover picks up the threads the housing used, at the figures Kawasaki specifies for them. No hole is opened out and no thread in the head is touched.
Homologation
The system is part of the motorcycle's approval where it is fitted, and removing it moves the machine into competition use in those markets.
Twenty Minutes Once Exposed
The work itself is short. Everything else in the job is getting the tank and airbox out of the way.
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.
Torque, Not Force
The specified figure is low and the temptation to exceed it is high. Resisting that is the entire skill involved in this job.
The Airbox End
Removing the housing leaves an opening where the hose attached, and unfiltered air into an intake is a worse outcome than the system ever was.
Kawasaki Returns to the Naked Litre
After the Z1000 ended and the Z H2 took a very different direction, there was a gap for a straightforward large four. The Z1100 fills it, and it does so with a full modern emissions package.
Sugomi, Refined
The styling is unmistakably Kawasaki and noticeably less extreme than the 2014 Z1000. It has aged into something rather more confident and considerably easier to live with.
