tkeagle, the rear swing arm cracking on the yerf is very common once u start riding it hard espically off roading. Its happened to me and a couple of others here. Don't just weld the crack reinforce around the rear engine mount with some pieces of steel. I also cut a tube and welded it at the lower end of the swing arm from one side to the other to reinforce it, and welded a piece at the rear motor mount its under my yerf dog thread new life theres some pics.
