RZ Carbs

It bothered me that the original petcock would continually drip really slow when I would pull the tank. It was epoxy-modded. so reserve was not a thing anymore.

If you have the OG petcock and there's no vacuum line, it probably has epoxy in the the rotating stem passageway.

There's a thread above from Kawtriplefreak where he did a splendid job working out an RD400 lever style petcock to make it work with an RZ knob. Probably lined up just right. I took the lazy boy route.
