Been reading up, and these engines don't really seem that complicated. I'm a parts swapper but am pretty mechanical. I just havent ever really gone inside an engine by myself. Those of you with more engine experience, would you recommend me just pulling this engine and replacing the crank bearings keeping my crank and doing a top end, or finding a used crank assembly and rebuilding top end, or just sell the bike and move one. I could get $750 for it and only have $300 in it, but do like projects and like the way it sets.
