Since I'm working on swapping out the gas tank on my Sportster, I figured it was a great time to replace the petcock (aka fuel valve). The stock one was fully functional but I wanted a change. After reading a lot of great reviews, I decided on a Golan Click-Slick Ball Bearing Petcock. I got the chrome 22mm with the down-facing outlet.
I'll install it once I finish clear coating my tank.
