I need some input...
My understanding is that the petcock should not leak any fuel when it is not recieving any vacuum. My trouble is that when removing or installing my tank, mine is usually gushing fuel out (gets a little messy). This happens in either 'on' or 'reserve'. However, if I let the bike sit, the carbs appear to be sealing very very well. There is no gas smell and the crankcase does not fill up with gas.
Do your tanks leak when you take them off?
Thanks
