good luck with the bike, we are here to answere any question you guys have, there are even a few members on here that build custom parts for these bikes.
tell your dad get the squish fixed on the head, run cometic gaskets and run the billet washers and the rm250 bearing for the top end rebuild. there are a few more cheap/free fixes for that zilla on here.
