Before I put the bike away for the winter, should I: (1) fill the tank with fresh gas plus "Sta-bil" & run it until the mix fills the carbs? (and if I do, will I have to drain all that out in the spring?) (2) drain the tank & carbs? (3) leave it as is (just a bit of gas in the tank & carbs) & worry about it in the spring? Seems to me if I drain everything, all the seals will dry out & crack. In the past, with other bikes, I just parked them, and in the spring, dosed the old gas in the tank with some lacquer thinner, which replaced all sorts of lost volatiles and cleaned out any crud. Always worked, but now I am more concerned with this bike....
