Your describtion of the problem to do hypermiling is identical for all scooters with vario drive. In the past there where scooters with 4 speed gearbox like Vespa. The only way to do EOC is in my view to build in an overrunning clutch ( see the thread manual disengage for a centrifugal clutch of Atomic). By doing that the only way to reduce speed is by braking, no engine braking possible. In a number of weeks from now I will be able to give results. Short term I have to recover from a surgery I had to undergo.
I checked the engine type on Google. With a stroke of 57.8 mm for your engine the revs your making at 60 MPH do give a piston speed of 14.4 m/s . A lower value should help to reduce engine losses, but that is not easy to make.
