Cool thread! I have a nearly identical bike, except mine is a '77. Same color, same leaking gaskets, same low mileage (mine has 12,000 verified miles). I am treating the gas tank with POR-15 and will try and do the pushrod seals soon (if it gets over 20 degrees at night sometime). I already replaced the floats, rebuilt the petcocks and replaced the pan gasket. It is really uncanny how alike these bikes are, I must post a pic.
