Essential box for any urban two-wheeler workshop: these BIHR jets in Ø5 mm are designed for SHA/PHBG type carburetors and allow for fine adjustment of the fuel mixture for scooters and small displacement bikes. Presented in a box of 10, they cover a useful range of calibrations for common adjustments and mixture diagnostics.
Each jet facilitates the adjustment of the fuel mixture and engine behavior (idle, acceleration, revving) without structural modification of the carburetor. Ideal for tuning sessions in the workshop: quick disassembly, testing, and replacement to find the appropriate calibration based on altitude, fuel, or needle settings. Convenient packaging of 10 pieces to cover a range of progressive adjustments.
Examples of frequently affected models: HONDA CAMINO (1990–1991 - 50 cc) and HONDA MB S 50 (1988 - 50 cc). Check compatibility with your SHA/PHBG carburetor before installation.
