Mikuni N151.067 Pilot Jet

Get precise, consistent off‑idle and low‑throttle response with the Mikuni N151.067 Pilot Jet series, available in sizes 30 through 60 to dial in your mixture exactly where you need it. The N151.067 is the non‑emulsion (non‑bleed) counterpart to the BS30/96 pilot jet, commonly referred to as “the 30/96 pilots without the holes.” This design uses a smooth shaft with no cross‑drilled emulsion holes, giving predictable fuel delivery in carbs that are specifically calibrated for a non‑bleed pilot circuit.

Each genuine Mikuni jet is stamped with the square‑within‑a‑square logo and size marking (and in some cases a “3Y” series code) for easy identification during tuning and servicing. The N151.067 shares the same overall length (14 mm) and M5 thread as the BS30/96, but because the BS30/96 uses six bleed holes, the two types are not interchangeable – using a non‑bleed jet in a carb designed for a bleed‑type pilot will cause major tuning issues. These jets are widely used across Ducati, Yamaha and many other models running Mikuni carburetors, making them a solid choice for restorations, upgrades, or precise jetting changes after exhaust, intake, or engine work.
