Hello my friend.... Sure you can get into the habit of turning off your Petcock but on most motorcycles they have vacuum cutoff, so its not necessary to always turn off the Petcock, if your having problems with fuel starvation, first check fuel filter and the check the vacuum hose from the Petcock to the Carb or Manifold.. I can tell you for sure this vacuum valve can give you all sorts of problems from moisture in the fuel or weather damage to the rubber hose...
