You cant use Wiseco rings on an OEM piston.

Take your cylinder and piston to the dealer. Have them measure it to see if it needs bored. If it does not need bored, have them hone it, and order new rings for the piston you have.

usually when you hone a cylinder your end gap on the rings gets real close to outer limits, so i usually get the next size over rings and gap the rings to the smaller end of the specs to be fresh again,,,, every little bit helps,,, :D
