KEIHIN MAIN JET 60 — Manufacturer reference: 99101-357-0600
Keihin main jet size 60, replacement part designed for carburetors equipped with interchangeable jets. This jet controls the fuel flow at full throttle: its size directly affects the air/fuel ratio at the top of the rev range. Essential for maintenance, leveling, or fine-tuning the carburetion settings, it allows for adjusting the mixture to achieve consistent engine response at high-speed ranges.
Symptoms indicating a change or adjustment: engine stuttering at full load, loss of acceleration in the high range, or replacement following a carburetor overhaul. Installation and tuning must be done in accordance with the carburetor specifications and, if necessary, after road or bench testing to determine the optimal jet.
Suitable for riders seeking an original Keihin part for their maintenance operations or to fine-tune their carburetion settings. For precise tuning, combine practical testing with consulting the jetting charts recommended by the carburetor manufacturer.
