DescriptionThe whole story▼
The JP ES 028 blanks the GSX-S750's PAIR ports with a machined aluminium plate in place of the reed box.
Key Features
- Suzuki GSX-S750 (2017–2021)
- Blanks the PAIR ports in the cylinder head
- Machined from solid aluminium
- Sealed with an O-ring, no gasket cement
- Uses the original fastener positions
- Fully reversible to standard
The Reeds
One per cylinder, in a plastic housing bolted to the head. They open on pressure drop and they are the only moving part in the mechanical half of the system.
What Goes Wrong
Cracked reeds pass exhaust gas back up the hose towards the airbox. The residue is unmistakable and the fault is usually found while chasing something else.
A Solid Blank
Machined from one piece with an O-ring groove. Nothing ages inside it and the sealing face stays true through as many heat cycles as the engine sees.
Three-Mode Traction Control
Suzuki fitted it as standard when rivals were still charging for it. The system is simple, it works in the wet and it never became a talking point.
A Low Seat
Eight hundred and twenty millimetres, which suits a great many riders who find modern nakeds too tall. It is a small thing that sells a surprising number of motorcycles.
Before Any Mapping
Unmetered air in the exhaust ports makes gas analysis meaningless. Removing the system first is the only way the resulting numbers describe combustion.
Five Model Years
The fitment covers 2017 to 2021, the run before the GSX-8S replaced the model. The head arrangement is consistent throughout.
Not the Electrical Half
The ECU still tests the solenoid circuit. Blanking the head does nothing about the fault on the dash.
Type Approval
Emissions equipment forms part of the approval and its removal ends road legality across Europe.
Reversible
The standard housing refits on the original fasteners. Keep it and the motorcycle returns to specification whenever it needs to.
