Just talk to the local dist. He said the internal are same. The only different is the carb (shorter LSN). And the engine mounting area. As I fit mine in a MRX5, have some clearance problem with the belt tensioner and the rear drive pulley. So I need to sand down the engine mounting tap slightly. But v1.1 was done at the factory.
