Leaking gas

hello everyone, I am new to the forum. my name is david.

I have a 1990 kz1000p. when I stand it up to start it after it has been leaning on its stand, i've notice gas leaking out of a spigot underneath the seat. it seems like it is directly underneath some type of filter? Is this supposed to be happening? i didn't notice it until i started keeping it in a garage and it was spilling onto the floor. it seems like a tube is supposed to be attached to the spigot? any thoughts are appreciated and welcomed. thanks to all!

I am no expert on older bikes. But I am pretty sure it's not supposed to do that.

Welcome to the forum, I had a 1989 suzuki 750 for my first bike. It would do the same thing, I took off the tank and the rubber hose was clamped on half ass.. so there for the gas was using 3/4 of the hose and the other 1/4 of it was leaking and sliding down the tube onto the engine and then the ground.I would take the tank off and follow the hose and make sure it's securely onto the male end.

All this is just ADVICE because at the end of the day, you can do whatever the FUCK you wanna do.

Whore your slut out

One of the things with side stands is that carb floats are more likely to stick a bit. The float bowls get a little over full and when you lift the bike there's some spillage. Turning off the engine and waiting a few seconds before dropping the bike onto the stand from being upright might help as this makes sure that the fuel tap is closed. Make sure that the fuel tap isn't set to Prime as well.

There are lots of other possibilities though. One is that the spigot is the air filter drain, in which case it's more likely to be oil than gas. This could be a result of an engine that's perhaps due for a rebore and new rings

There is supposed to be a tube attached to the spigot you mention, whichever one it is. It's to make sure that any spillage is routed down to the floor below the engine. You don't want drops of fuel accidentally hitting somehing hot, and you don't want it hitting anything that should be lubricated, as it washes the oil or grease away. If it's drops of oil (often mixed with a little gas), it makes a mess.
