There is an adjustable stop on the centerstands upper mount, this should be adjusted so that the stand retracts as far as possible. The pedal arm should have little or no clearance between the muffler.
Even when it is adjusted properly it is possible to drag or scrape the bottom of the pedal arm when it curves around the muffler during severe or hard cornering. Dragging of the left foot peg or floorboard (if so equipped) will occur at approximately the same degree of lean angle (severe or hard cornering).
This is not a design flaw but rather a design limitation dictated by the manufacturers design of the motorcycle itself.
