Just an update- I bought this bike from Steven and is now looking great. Put the correct seat on with seat lock, degreased and power washed engine, adjusted timing chain, valves, rebuilt carbs, synced carbs (get a carbtune!), put new dunlop d404s, new brake pads, new turn signal relay, and new mac 4-1 exhaust system. The bike runs great save that it is a little to lean and doesnt really run out that well. Will raise needle adjustment to richen mixture. Still smokes perhaps due to bad rings and those will be replaced this winter. Perhaps a full engine rebuild is in order. It's been a very great first bike for me! See attached pictures- I have left the tank on it that stephen found and it retains just the right amount of flat black patina!
