I used to work on a shim adjustment engine and it is a pain.  Granted, CHECKING
to see if the tolerance is not too bad, once you take off enough stuff to get
at it - but, the adjustment process usually requires a fair amount of
knowledge, skill, and time. Also, you might need special tools. It is easier
to get a bike that doesn't use them.
