Adding a knife edge along the top of the tail has proven to instill oscillation for some reason and trying to spoil the lift (side) of the vertical wing will be very much less effective back there than using a spoil strip right along the nose since the greatest lift force will be at a location just behind the max thickness of the wing.

Venting the pressure differential with openings across the bike at the max thickness is the best and simplest way to improve handling in side winds. And judging from the air movement I feel ripping across the gap when riding my PCX150, the cross sectional area of the vent will need to be on the order of 1 square foot. Maybe 2.
