the Yamaha RD200 workshop manual (downloadable off the forum) explains armature removal. The manula shows the use of a slide hammer attached to the centre of the armature.

its not easy, these things never are, its been there for nearly 40 years and it wont like coming off.

The trick is to ensure the engine case is securely mounted on a fixed bench and use the slide hammer to provide a "jolt" to release. its an interference fit on a taper so they are a sod. Don't be tempted to use a bolt through the armature on to the end of the crank (as the 125 magnet removal) as its very easy to damage the end of the crank web where the advance/retard mechanism fits in

Growing old is inevitable, growing up is optional
