DescriptionThe whole story▼
The JP ES 041 is what an owner fits to the Diavel 1260 when the reeds in the secondary air housing have cracked, which happens with heat cycles rather than mileage.
Key Features
- Ducati Diavel 1260 (2019–2023)
- 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
Not Really a Cruiser
Ducati built a sports bike with a low seat and a wide rear tyre, and the riding experience has almost nothing in common with an American cruiser.
Why Improvised Blanks Fail
A bolt and washer or a smear of epoxy holds for a while. Neither survives a season of heat cycling, and epoxy has to be chiselled off a head.
Torque Into Aluminium
The fasteners thread into the head and Ducati specifies a figure for good reason. Guessing at it turns a twenty-minute job into a thread repair.
Aluminium Against Aluminium
The cover seals on an O-ring rather than metal to metal, which allows repeated removal without damaging the head face. It is the correct answer.
The Case Against Improvising
A bolt and a washer, a rubber bung or a smear of epoxy will all hold for a while. None survives a season of heat cycling.
The Reeds Are Not Serviceable
Ducati supplies the housing complete. A cracked reed means a new assembly, which is part of why owners choose aluminium instead.
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.
Thread Locking Compound
Ducati specifies where it is wanted and where it is not, and a cover held by two small fasteners into an aluminium head is generally a place for correct torque rather than for chemistry. Adding compound because it feels thorough makes the next removal harder for no gain at all.
