My "barn find" 75 is torn down, engine out, and i'm in the middle of the "bringing back an old Goldwing engine," a la posted by someone on this forum, and have a few questions. The bike sat for 30 years outside under a tarp. There has been rust in plenty of places. I may end up replacing the engine, of course, depending on what happens when I try to start it in a few weeks. I've replaced the timing belts, had the starter checked out by a shop (it was good), rebuilt the carbs, floated the engine for a few weeks in oil/kerosene. The fuel pump I'll check out when the engine is installed, before hooking the hose to the carbs. The fan works, I had the radiator cleaned and pressure checked, it's fine. I've cleaned and sealed the tank. New hoses all around. Ignition system checks out, new points, timing set. Two things he doesn't cover I wonder about: should I worry about the water pump, maybe take it apart and inspect it? What about the valves - should I take the valve covers off and check the valve clearance despite the fact that I'm sure it's going to look ugly in there and perhaps the valve seats are crapped out and would affect the clearance until it starts and blows out the crap...
