DescriptionThe whole story

The JP ES 041 is the mechanical half of the secondary air deletion on the Multistrada 950: the housing comes off the head and aluminium goes on in its place.

Key Features

  • Ducati Multistrada 950 (2017–2021)
  • 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

An S Version With Skyhook

Ducati offered semi-active suspension on the higher specification, which is the main difference and worth the premium on a loaded bike.

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.

Fewer Perishables

A moulded box full of reeds is one of the few genuinely consumable items bolted to a cylinder head. Aluminium removes a future job.

Refit for an Inspection

Where periodic testing covers the equipment, the standard housing goes back on in twenty minutes with nothing needing replacement.

Nothing Structural

The housing carries no load and its removal affects no part of the head's sealing or cooling. It is genuinely a bolt-on component.

A Job for the Same Session

The tank is already off for the electrical half, and taking it off twice for two twenty-minute jobs is a poor use of an evening.

The Hose Port at the Airbox

Removing the housing leaves the intake end of the hose open, and closing it is not optional. Unfiltered air entering an engine is a considerably worse outcome than the emissions system ever was, and it is the single most common thing left undone in an otherwise careful job.

What the Ports Look Like Underneath

Two small drillings into the exhaust side of the head, machined flat around their edges so a seal can work. There is nothing delicate about them and nothing that needs protecting, but they should be wiped clean before the cover goes on, because a piece of grit under an O-ring is the one way this job leaks.
