Thanks for the advice.  I think it all boils down to the guy I got it from let gas sit in it over a year. As far as the petcock?  I think you refer to the fuel valve on the underside of the tank?  No I have not taken that appart, but from what I can see it is one line that feeds both of them (unless that is the return line?)   My other worry is, I put a good 800 miles on it with it only running on the one side.  Could that of caused more damage?  Also I have seafoam in the fuel right now, should I continue to ride it?  So many questions.  Le Sigh I didn't want to get into the Fix and Repair aspect of this all until at least next season.
