Well, it's a sad night. Had the bike running last night, but was having carb float issues and was only able to start with starting fluid. Adjusted the problem float, went to start it, and it ran for 10-15 seconds, coughed, and then died. Left it for a day, then went into the garage this evening to do a float level test. Went to try starting it quickly, and it wouldn't kick over. Tried turning at the points plate but felt like I was going to shear the nut off. Bike is not in gear at all.
Will try pulling the plugs and putting some WD40 or something in and let sit overnight. Worried that for some reason I may have starved the top end, even though I had removed one of the tappet covers and checked to make sure oil was getting up there. How long would it take for the bike to seize if an oil jet were plugged? I recall reading about someone getting glass beads stuck in the jets.
Oil pressure was good while it was running. Was consistently at 60psi. If anyone has any other suggestions I'm all ears.
