I had a year old 73 500 k2 and my wife wanted to ride. I unselfishly proposed trading the 500 in on two 360's. The dealer said he would sell me one 360 and trade the second one even for the 500. Well, why would I do that? No F'n way. I said I'd buy her a 360 and keep my 500. What happened instead was I saw a used touring cb750 for sale priced right so I bought it and gave her the 500. Win, win! We both ended up with 4 cyl bikes.
