I am not totally opposed to lapping, but to indiscriminate lapping as the inexperienced are likely to indulge in based on most of the readily available info. If the axle and/or hub are significantly distorted as is often the case launching straight into vigorous lapping just ruins both.
(Some fits may be superior to a uniform lap ie interference at the large end of taper. On very many other makes and on the later Seven flywheels tapers are deliberately relieved in the middle. Failure of tapers in general is reckoned to commence from the large end.)
