fuel leak

[crixal]

i have a 2003 model, after i ride a wheelie, go up a hill, or load it in the truck it leaks fuel out of the line that goes from the carb down to the swing arm. i'm guess it's a drain? any ideas?

yeah, its an overflow tube, its supposed to do that.

it does it when it's idling sitting flat.

Check the float needle valve in the carb, you'll have to take the float off to get to it. Make sure the needle springs in/out freely from the valve.

A sticking/faulty needle valve will cause fuel to pour out of the overflow hoses while the quad is level.

Also check the float bowl drain screw just to make sure it isn't cracked open slightly. On the left side of the quad down by the choke, and near the bottom of the carb, the screw will be facing directly at you. Make sure that screw is tight.
