Leaky Petcock

[shawman]

I have a 2000 1500 Classic. Last saturday I pulled it out of the garage and when I turned the fuel valve on, gas stared coming out pretty good at the valve handle. I took it apart and inspected the rubber gasket and o-ring. they looked fine, but I ordered a rebuild kit anyways. This is my first time turning wrenches on my bike. I know it's a pretty simple procedure but
I want to cover all of my bases.

How come I didn't see any defects with the original o-ring? Should I coat the rubber with anything before install? My bikes only 9yrs old; is this normal?

I know I have quite a few questions but like I said, "covering my butt" As much knowledge as possible would be greatly appreciated.

Thank you, Shawman

When you have the valve apart, clean it,look closely if there are any scores in the metal, and use a bit of silicone grease or petcock grease if you have it on the sliding surfaces. Don't use petroleum based grease as it will eat the O ring over time and cause another leak.
O rings dry out over time and its not that unusual on an older bike.

The rubber parts are worn out likely, and don't appear to be bad to you. Do what Ring says.

Thank you again. Kudos to you both.
