Bandit 600 fuel tap

Long story short , 600 Bandit after being turned back from Reserve to On
starts flooding number 4, via the vacuum pipe leading to fuel tap.Yes it
now does this permanently.

Before dismantling is there anything obvious should look for in fuel tap,
had heard that this was a vaguely known problemm with some vacuum taps .

Thanks

Are you sure the float level isn't set too high on #4, or that it doesn't have
a stuck float valve?

If you suspect the petcock, though, look for a torn diaphragm, a a damaged
dingus attached to the diaphragm which actually shuts off the flow of fuel, or
a 4-hole rubber grommet with tears between two adjacent holes...

I have recycled the grommets sometimes by just turning them over, or rotating
them 90 degrees so the tear is realigned to a different fuel port...

It seems to me that if the vacuum diaphragm that opens the petcock in the
normal On position was torn, the flooding would occur in the Res position,
too...
