Another Nighthawk post! I'm currently undergoing an engine rebuild for my 1983 nighthawk 650, and looking for some advice. The engine was seized, and is completely disassembled now. I'm starting the rebuild and need all new gaskets, bearings, etc. I'm looking for a source for said parts! The head and crank case are off being checked, and I'm washing everything at the moment. The valves were covered in corrosion, but hopefully can be salvaged. Thanks for the advice!
