Hey fellas, i've been a member here for a little while but this is my first post. I have a 1979 630 that i brought back from the dead and am very pleased with. My question is does anyone know of a reliable way to check the fuel on my machine? There is no guage or sightglass that i can find and checking it with a stick is fairly ineffective (the angle of the filler neck results in hitting the other side of the tank before the bottom). Any help would be appreciated. Thanks, Roy
