I have changed the mag wheels fitted to my '71 500 k for standard spoked wheels. All fittings are present as per the manual but I have 5mm sideways play of the wheel on the front sprindle. The gap between the spacer and fork is the 5mm and can be seen clearly on the two attached pics. I'm thinking this shouldn't be any measurable movement and now wonder whether the front mag wheel may have been 5mm greater in width, unless someone can suggest another reason for this? Unfortunately I don't have the mag wheel to measure.
