After dropping a ring on my WR250 Two stroke last year I had the barrel welded and re-coated by an Aus. Company called Electrosil (about $400 Aus).
Honing will mean it needs recoating.
It will only need honing/recoating if it has pretty serious marks in it.
Whilst my experiance unitl recenlty is with 2strokes, the barrels only need redoing when they are scratched. I put several pistons in the barrel before the ring tore it and it needed repairing.

If you have no compression after your're finished (and the cam timing was done right) don't worry, had the same problem. Kick a few times, it will probably start and after that you will feel the compression = oil was sprayed on the cilinder wall.
