・Primary application is the 1979–1982 Honda CB750F DOHC family using 30 mm (1.18 in) Keihin VB-series carburetors.
・Carburetor identification suffixes and internal calibration changed by model year and market, so exact year-specific interchange should not be assumed from appearance alone.
・CB750K, CB750C, CB750SC, CB900F, and other Honda DOHC four-cylinder models may use visually similar Keihin VB carburetors with different identification numbers, jetting, linkage, or calibration.
・Please compare the carburetor identification stamping, intake spacing, throttle / choke linkage, accelerator-pump arrangement, venturi size, and original Honda specification with your motorcycle before purchase.
・Professional rebuilding and synchronization are strongly recommended before road use.
