Late update: after trying a few of the tips you guys gave me, engine is coming out. No change in ticking/knocking sound. Was able to go for a quick ride down the hill and around the school parking lot a few times to see if getting it nice and hot would loosen up a stuck lash adjuster if it was that, no change and just plain sounds like crap. No big deal though, been going through Roach's rebuild videos and doesn't look bad at all. Found some metal flakes in the oil screen so it needs to happen anyway. So my wife and I will tear it down this fall/winter and check everything and do needed upgrades. Will be a good time to do other stuff also. I'll update on progress and any issues found and total cost along the way. The bike was free but I really like it and am willing to put a good lump of cash into it to make it run great and give it another 20 years of road time.
