New fuel valve / petcock for Honda CB500K, CB750K and the '74 CB550. When the stock petcock can't be rebuilt this is great replacement to save time so you can get back to riding!

Stop / On / Reserve. Built in fuel filter. Fuel exits straight down through dual outlets. Comes with the o-ring that seals against the tank and two M6 x 35mm mounting screws with sealing washers.

7mm (1/4") dual ribbed fuel outlets.

Replaces Honda part number: 16950-300-020

NOTE: Can be used on the CB350F. The CB350F originally had one fuel outlet, so you will need to get a 2 into 1 fuel line fitting. Fuel line routing will not be ideal but can work.

Fits Honda:

CB350F - 1972-1974 (See note)
CB500K - 1971-1973
CB550K - 1974
CB750K - 1969-1974

    Correction OOPS I’m an idiot

    Posted by Paul Pinajian on 15th Aug 2020

    Previously reviewed this item and had given it a negative review which needs to be corrected. The product actually works perfectly. I neglected to see the Tiny arrow on the petcocks handle. All my other Honda’s ( I have 11) the handle lever itself is the pointer to the valve operation wording. This valve is the opposite from all my other Honda’s and has an arrow that points to the words open stop reserve. I thought I was closing the valve and was actually setting it to reserve and thought the valve wasn’t holding in the stop position. My mistake. Maybe the product description should disclose this info. This is not how the original one operates. Also the wording on the face of the petcock is on the top side of the perimeter ring and once installed is obscured by the edge of the tank. The original Honda petcock has the wording around the bottom edge where it can always be read . This product functions perfectly but for these reasons I can’t give it 5 stars I am still happy with the product for the price

    I read the note about fitment, but finding an OEM style petcock is near impossible. I capped one fitting and it works fine. The aft outlet does contact the carb body if the tank moves back far enough, but if you protect it enough it'll work fine.

    Fit CB350F

    The only new aftermarket petcock available for the cb350f and it's great! The only downfall was the two fuel lines. Id recommend not going with the "Y" fuel line connector and going down to an auto store and picking up a hose plug to put over one of the fuel spouts. The Y connector kept getting twisted and pinching. quick fix and super cheap.
