Despite the fact that the 'white wire fix'is promoted as a temporarly solution to overcome the 5500 rpm problem, it is also not always a functional work-around. I personaly think that it will be depended on the place/type of the mal-function of the coils on the stator.
As Kees said, I also suggest a Ignitch
A 5500 rpm problem is in most cases the stator, but yes, it can be the CDI. Not likely, but stranger thing can happen......
