About the Honda CL125S
Carburetor, engine and fuel-system repair guidance for the CL125S, with model and year checks for every linked part.
The linked Honda CL125S1 crankshaft fiche shows the single-piston layout. Keep CL125S separate from the CL125A twin when selecting the 1973–1974 overhaul gasket set. Record a replacement engine independently of the frame’s model and registration.
Start with the S-model engine identity
The shown fuel valve, reference 16950-107-000, and cap, reference 17620-402-000, each list CL125S 1973–1974. That model-year match does not identify a donor tank’s attachment or filler. Compare valve mounting/outlet and cap retention on the tank that will remain on the motorcycle.

Prepare for the repairIdentify your CL125S and the fitted part
Check the model code and year
Confirm the complete model code and year from the motorcycle’s identification label or registration. Use CL125S, not a shortened family name, when a product separates related models.
Match the part already fitted
Compare the original part with the product photos and specifications. Check markings, dimensions, mounting points, left/right or front/rear position, and the quantity supplied.
