DescriptionThe whole story▼
The JP ES 041 is the mechanical half of the secondary air deletion on the X Diavel: the housing comes off the head and aluminium goes on in its place.
Key Features
- Ducati X Diavel (2016–2023)
- Blanks the secondary air ports in the cylinder head
- Machined from solid aluminium
- O-ring sealed, no jointing compound
- Original fastener positions
- Standard housing refits at any time
Ergonomics in Three Dimensions
Ducati offers pegs, bars and seats in multiple positions, so the motorcycle can be fitted to the rider. Very few manufacturers bother at this level.
An O-Ring, Not Compound
The joint separates cleanly years later with nothing to scrape from the sealing face, which is not true of anything bedded on jointing paste.
Keep the Housing
It refits in twenty minutes with no new seals, and having it is what turns an inspection or a suspicious buyer into a straightforward evening.
Where Owners Go Wrong
Overtightening into an aluminium head, which converts a twenty-minute job into a thread repair and a considerably longer afternoon.
Access and Sequence
The tank comes off and frequently the airbox as well, which is why this belongs in the same session as the electrical half or any other work under there.
What the Lambda Sensor Sees
Air injected downstream of the valves reaches the sensor as extra oxygen, and the controller reads that as a lean mixture it did not create. Removing the source is what makes the reading honest again.
Why Aluminium Instead
There is nothing inside a machined cover to age, nothing to inspect and nothing to replace for the life of the engine. It seals on an O-ring in a turned groove against the head's own finished face, which means it can come off and go back on repeatedly without damaging anything underneath it.
Refitting Years Later
Because the cover seals on a ring rather than a gasket, the head face is exactly as it was when the standard housing goes back on. That is the property that makes an emissions inspection a formality rather than a gamble, and it is worth more than the cover itself.
