Engine from Slipstream

Had a chat with Martin Sweet of Slipstream Tuning today regarding the use of their MZ/Yamaha motor for Gordon next year. As Im not a hard rider Martin suggested reducing the cc from 760cc to 720cc by fitting a standard stroke crank,(more reliability), he will strip and refresh the engine so all being well it should last the season with a possible strip down midway through the year. So all that needs to be done now is to find out when "Gordon" will be coming to see his new dad?
