White Brothers FCR Fuel Screw

[quadguy83]

Has anyone installed the White Bros Fuel Screw? I got one for my 06 450R. It came with an o ring and i'm not sure where it goes. Its not little like the one that goes up in carb. Maybe it just sits down in the fuel bowl to keep dirts out. Thanks

it probly goes up in the recessed area, to keep the screw from falling out. some people were having problems with losing the adj fuel screws
