This is the second time I have read of someone putting a large tail box on their bike and then dealing with stability problems. It seems that some of the no-name tail boxes are not tested on the bikes before production. It is possible that the aerodynamics of that box destabilizes the air as it passes over and around the box.

My suggestion would be to test a name brand tail box on your bike to see if it causes the same problem. (The base plate should be universal, so it should not be difficult to swap boxes.) The PCX has gone through some major design changes in the last few years. Some of those changes could affect the aerodynamics. Keep in mind that the newer bikes do not have a wide choice of tail boxes yet, possibly because of that problem.
