i have a 1985 gsxr 750. and the carb on the far left of the bike leaks.. its the side where the kickstand is..
now it leaks outa where you turn the bleeder screw to drain the carberatur. it only happens on the left side.. i got a rubber hose with a plug on the end and when the bike is left over night with the hose on, and in the morning when its removed it streams out gas for 5 seconds.
now the bleeder screw is as tight as can be. what else could it be?
when the bike is full upright it doesnt seem to leak.. but than again whenever the bike is running or cooling down from a run it doesnt leak... i was thinking maybe because the bike leans towards the left.. all the gas pools into that carb.. but still, it shouldnt be leaking out..
even if i turn the gas to off it will leak, cause gas is already in the line..
