Big John. I have read through this thread and it is a case of deja vu! Your bike sat awhile, and though in essentially good condition, has suffered from lack of ongoing maintenance.Notchy head bearing, bad seals, old tires. I have been there. Once you get it all fixed though, routine maintenance will keep it roadworthy for thousands and thousands of miles. Old airheads don't like to be" ignored"!
Go far or stay home.
