Oil and gas in air filter box.
new to forum and to bikes. i got a 95 suszuki 500gs. rode to work and upon leaving it wouldnt start. it would just "click". found gas in air filter box. took plugs out and turned the motor over. gas shot out from spark plug holes. put plugs back in and started it. oil started pouring into the air box. you could see metal flake in it. what would cause this?
