    Another reason not to use in line shut off valves

    New petcock came in today and I was happy to remove the inline cut off valve and go back to hands-off operation. I noticed something as I pulled the old assembly apart the inline shut off valves seem to be a large restriction to flow. As you can see from the pic the inside diameter is much smaller than the petcock's. Also the pass through in the valve is smaller than that. Might have something to do with the inline valves state they are not recomended for any displacement over 300ccs.
