Question about 1980 Suzuki Gs 550 L
Make sure the petcock is NOT in the PRI,or prime, position. This will open the petcock causing fuel overflow.

YES, replace the petcock.

Your petcock needs to be rebuilt (if parts available), or replaced, if it does not shut off the fuel. It also may not be saving reserve fuel , if gas is bypassing the ON position. You may also need a new fuel filter .Maybe add an additional in line filter. If you have replaced the float needles and the carbs are still overflowing you probably have a problem with rust in the tank. Have the inside of the tank cleaned or use a rust removal kit on the tank and see if this does not solve the problem. Try to avoid fuel tank liners if possible , they can cause more problems than they solve.
