How do you fix a leaking motorcycle petcock?

Remove the screws located on the valve (what you use to switch to the “on,” and “off” positions), remove the petcock and replace all the gaskets, bolts and screws. This is the simplest repair to most leaky fuel petcocks.

What is reserve on a petcock?

Reserve is selected when the long side of the petcock handle is pointing straight forward. The Prime setting (only on the ZZR250 — if you’re living in the US, you have an EX250, not a ZZR250) is used to bypass the vacuum diaphragm that normally stops gas from flowing unless the engine is running.

What does a petcock do on a motorcycle?

A petcock, or sometimes referred to as a fuel tap or fuel valve, is a 2 or 3 way valve on the bottom of your fuel tank. It works by directing fuel from your tank to the carburetors or fuel injectors. Fuel is pulled by either gravity or vacuum from the fuel system.

Can you replace a petcock on a Harley Davidson?

You can replace with any non vacuum petcock but it should be turned off every time you shut the bike off to prevent fuel over flow at the carb. Do they give their reasoning for that statement?

Where does the leak come from on a Harley Davidson?

It may be something small like a blocked vent line but you didn’t mention what area it was coming from. If it’s coming from the area behind the pulley, then it gets a bit more involved. Which side of the bike is it coming from and are you sure it isn’t a primary leak instead of the trans?

Why is the cover on my petcock leaking?

To be more specific, it’s leaking around the cover on the turn lever itself. You know the cover that has “Res” “On” “Off” stamped on it. I don’t know if I’m missing an O-ring or what. I’d like to try and rebuild it before buying a new one, it is vacuum operated off a ’96 Sporty 1200. Any suggestions?

How do you clean a Harley Davidson petcock?

Open the petcock putting it in the reserve position (to remove all the fuel). Then you have to apply a gentle vacuum to the vacuum port on the petcock. How you do this is up to you. I’ve attached a short rubber hose to a syringe and then to the petcock at which I draw a slight vacuum.

What to do if there is no fuel flow from the petcock?

If you know there is no fuel flow from the petcock with the engine not running, disconnect the fuel line from the petcock (you could remove it from the carb but working from the petcock is probably easier AND you don’t have to mess with the plastic carb inlet elbow which tends to break very easily). Then disconnect the vacuum line from the petcock.
