Hey everyone! I'm Will, a student halfway through college, and I bought my first Nighthawk and first bike ever a few weeks ago. It's an 83 650 that hasn't been given cared for in a few years and I'm halfway through cleaning it up and getting it ready to run. You'll see in the pictures that there's a nice hole in one of the pistons. I bought it knowing that (though not the cause) and figured it would be fun to dig into the engine a bit.
Other stuff I've done so far: - Stripped the carbs and let them soak in cleaner for a day each. I needed to get one carb kit because a jet was breaking down and one of my diaphragms was torn so I got a replacement for that, overall they seemed fairly clean. - The front brakes were awful. Sadly I forgot to take pictures but there was a half inch of brown jelly with solid particles in it just sitting in the brake fluid reservoir and a nice layer of dried brown crap on the brake line Y split. The brakes were seized when I got the bike but flushing the brake lines for a few hours and letting the actual calipers soak in brake cleaner for a day they're working just fine. - Broken piston slightly damaged the cylinder head and broke a valve so a new head and valves were ordered (still not sure if I'm going to replace the head yet as the new one is missing quite a few exhaust studs). - Re-greased the final drive gears. I also got a battery over the weekend to test the electrical system and ran into an issue I'm not entirely sure about. When I first plugged the battery in and turned the bike on, only the oil pressure indicator and neutral indicator light came on. I then sat on the bike, pressed some wire somewhere, and everything came to life right before going dark when I got off. I have the Clymer's manual and I'm pretty sure that the regulator/rectifier isn't working as expected (I think it's the only think that controls power for that many components) but do you guys have any suggestions for other components I should check?
