DescriptionThe whole story

Removing the secondary air system from an MT-03 is two separate jobs, and JP ES KIT05 contains the parts for both: the plate that seals the head and the eliminator that keeps the ECU quiet.

Key Features

  • For the Yamaha MT-03A, 2016–2025
  • CNC-machined aluminium plate with gasket
  • Electronic PAIR solenoid eliminator
  • Original threads, no drilling
  • Also fits the R3 that shares the engine
  • Reversible in full

Both Halves or Neither

Fit the plate alone and the diagnostics report a missing solenoid circuit. Fit the eliminator alone and an open port in the head vents exhaust gas into the engine bay. The half you skipped announces itself the same evening, which is the entire reason the kit exists as a kit.

A Small Twin Is Quick Work

The 321 cc parallel twin puts both reed valve housings along the top of a small head, reachable once the tank is lifted. There is no hidden cylinder and no bodywork worth speaking of. Of everything in this range, this is among the easiest bikes to do the job on.

Set Expectations

No power, on a bike that does not have much to begin with. What changes is the crackle on overrun and a small amount of weight. On a 300 being prepared for a lightweight class, the second of those is the point.
