Question about Yamaha XV 535 Virago DX Motorcycles
Some Viragos used a vacuum operated fuel petcock that allowed the fuel supply to open when the bike started and shut off when it stopped. There was a vacuum line from the intake to the petcock and this vacuum acted on a diaphram to open the fuel.
Sometimes the diaphram leaks and the intake vacuum pulls in fuel....causing a very rich mixture.
If you find it has a vacuum operated petcock, you could remove vacuum line and briefly open the
petcock manually using the PRI for prime position to see if fuel leaks out the vacuum port.
There are rebuild kits for the vacuum operated petcock
