My 1981 KZ 550 has been leaking fuel. I first noticed this after taking it out of the basement from its winter hibernation. If it sits, say overnight on its kickstand, upon getting on the bike and moving it prior to starting, there's a trail of fuel. It does not leak until it is moved. Today, prior to moving it I put a baggie around the four drain tubes that run to the four carbs to see if this was where the fuel was draining from, and, well it was parked in my basement (pic included)and I'd be in the dog house if it drained on the carpet. Sure enough the baggie caught about a 1/2 ounce or less of fuel out of at least one of the tubes. While I haven't isolated this problem to one of the four carbs, is this indicative of a stuck float? if so, what's the fix? If not the floats what may it be? The bike runs fine otherwise.
