just make sure you have the correct height on the piston meaning for the correct year. suzuki played with different rod lengths from 98-04. they went from a long rod motor 110mm length which used a shorter piston, to a shorter length rod with domed piston around 98mm i think??, then in 04-up the switched back to a long rod 104mm with flat top piston.
i only mention this as i was was given the 03 piston for my 04. it was taller and domed. i somehow got it started but i noticed the spark plug kept backing out after riding and i was down on power. i pulled it apart and the piston was slapping the head. it ended up damaging the crank bearings
