I've heard about the 'petcock mod' but searching turnud up nutin. A free'ier flowin petcock would be keeen. Shed some lite on it. Worrien about the wrong bowls being not big 'nuf.

The petcock mod is where you grind an extended channel into the fuel valve letting it turn 180 degrees from the "off" position allowing both "on" and "reserve" to flow at the same time. Flow is noticeably increased. I removed both pick up tubes off of mine too, but I remove and drain my tank on the regular and keep it clean.
