About the Honda CB350
CB350K and CB350G are twins. CB350F is the Four. Start with that distinction.
Honda sold two very different motorcycles under the CB350 name. The classic twin uses an air-cooled overhead-cam two-cylinder engine; the CB350 Four, introduced in 1972, has an inline four-cylinder engine. Similar badges hide different cylinder heads, gaskets and carburetors.
Choose the motorcycle, then the repair
Use the CB350K twin guide for its year-specific carburetor, clutch and fork applications. The 1973 CB350G guide covers the late twin and its front disc brake. For four-cylinder engine work, go directly to CB350F Four parts.
Know your CB350 before choosing partsCB350 twin and Four: the differences that affect parts
These model groups share a name, but they are separate starting points for a restoration.
CB350K twin
Two cylinders; year-specific service parts
The K guide includes a 1970–1972 carb kit, 1970–1973 gasket set and 1968–1971 fork seals. The different ranges belong to those individual parts.
CB350G twin
1973 front disc, rear drum
The G's hydraulic front brake uses a caliper and master cylinder. Rear drum shoes are a separate purchase. Its featured carburetor repair parts explicitly include CB350G 1973.
CB350F Four
A separate four-cylinder engine
Four-specific carburetor and engine-gasket applications belong here. A shared brake or chassis part does not make twin engine parts suitable for a Four.
