1971 Honda SL350K1 · Fuel System Buying guide

Follow the repair from the tank to the carburetor

Tank hardware and carburetor internals have different matching requirements. A petcock thread, a filler-cap hinge and a needle-and-seat set each need their own comparison with the fitted equipment before the order is complete.

Match the tank fittings physically

The petcock has an M16 × 1.5 thread. Compare that connection and the available clearance with the actual tank before ordering. For filler-cap work, inspect the hinge and latch separately so that a new cap is not expected to correct unrelated worn mounting hardware.

Identify the carburetor before buying internals

The linked float-valve set includes its needle and seat. Choose it against the carburetor fitted, then decide whether bowl sealing or screw replacement is also needed. Those separate repairs should be based on inspection rather than an assumption that one small kit supplies everything.

Buying questions

Will the petcock fit an aftermarket or changed fuel tank?

Measure the tank connection and compare it with the petcock’s M16 × 1.5 thread. Also check outlet clearance; the motorcycle’s model label does not identify fittings on a replacement tank.

Does the chrome cap supply both hinge and latch hardware?

It includes a gasket, hinge pin and E-clip. The latch is a separate assembly, so inspect that mechanism before deciding whether a cap-only order covers the repair.

Should I order a float valve for a carburetor overflow complaint immediately?

Identify the fitted carburetor and inspect the cause first. The offered set contains a needle and seat, but the repair may also depend on the float, its adjustment or contamination.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
