I have recently acquired a 1987 YZ 250. When I got the bike it was not running due to a top end failure(which I intend to send to eric for resleeving service.) I have decided that now would probably be a good time to rebuild the bottom end as well and was hoping that someone could give me some good tips on how to separate the cases without having to spend the money on a tool that will not see that much use. This may also be a dumb question, but would eric's book be a useful tool to have before I start, as this is my first attempt at a bottom end?
