Honda cb550

I have a 1977 Honda CB550 that I put to much money into with hopes + dreams of making an old school cafe racer. It has sat untouched + collecting dust for 2 years. Pretty much stock, except for the aftermarket 4 into 2 exhaust that was on it when I got it. Want to sell or trade...SO...what I like is my 72 Slant 6 Valiant, guitars, and amps. What I could make practical use of is a 4x8 utility/landscape trailer...I'm also open to suggestions....$500?
