6 speed in a GPZ750

Steve Darlington (a member here and on the GPz mailing list) lives in Canada and races a 750, but I "think" it's a 82 GPz750 (not sure though). He has mentioned that he is using the six speed (but I think it's not a 83-85 GPz motor) and a smaller chain. Maybe he will see this and post here.
