I'll address #3...
Possible. But I have no data on folks that switched to the TW200 petcock which is not vacuum actuated. If the bike has been running, it's engine vacuum that's holding the diaphragm open. It seems unlikely that constant energy would somehow "pause" letting the diaphragm close. Remember even if the cylinder isn't firing, it's still pulling air if it's still turning.
However, petcock diaphragms can fail. But I don't think the symptoms reported for POOGS match.
Well after I switched to the tw200 Seems like everything came together. I just bought the manual petcock for my KLR since it appears it has issues with the vacuum type as well.
