Vacuum petcocks usually leak in my experience they hardly ever seal off completely... My 2012 Ninja 250R 's vacuum petcock leaks real bad
it's like it's left on prime it's so bad ! i've had it apart 2 times but cannot find a thing wrong with it ! ...it just leaks !and there is no way to shut it off.
.....
if the tank is a bit Rusty I'ed say there's your problem ! the rust will make the
petcock leak and the floats leak too ....
I used Kreem tank liner in my gas tank and it did a good job no more rust !
I should have left the acid etch in longer though...
.....
Good luck fixing that monster !
