fuel tap /carbs leaking

[Delbert]

Hi

Can't seem to stop the carbs from leaking fuel from the outlet on the bottom of the float bowls , they are both doing it ,
I have replaced the needle valves with ones from norbo & rechecked the float height .
I run the bike out of fuel when I put it away but within a day or so its leaking again , so I'm putting it down to the tap not shutting off properly although the tap was refurbed with seals ,dare I say from yambits ,, I notice its worse the more fuel is in the tank due to the weight I guess ,, so any ideas if this tap is repairable or am I barking up the wrong tree ? Is it the carbs or both ?

does it still do it when the fuel tap is turned to off position

[Delbert]

Yes mate ' I turn the tap off & let it run untill it runs out of fuel ,, but the tap must pass by the seals as the carbs start dripping again within a couple of days

There is no reason why it should do it with the fuel left ON! Are you sure the bowl drain screws are not passing?

[Delbert]

Do you mean as in passing by the fibre washer on the drain screws ? I did think this but looked to be coming from the outlet on the bottom of the bowl , of course I could be wrong ! As you say it shouldn't leak with the fuel left on .
Think I will change the drain screw washers first and moniter .

Have you considerd that the fuel tap may have been taken part and put back incorrectly. I had this were the Rev was in play put fuel tap showed on postion.

Yes, that's what I meant.

If you take the fuel hose off the tap ,, with the tap in the off position you get a drip every few minutes , I think this is enough to refill the bowls in a few days then they start dripping . Arrow may have a point here as (to be honest ) the left bowl started this a while ago but now the other side has started I fear its time to do something about it so it coud be deterioration of the fiber washers leaking across the bowls and dripping from the tube ,
