First of all, #$%*tard, I don't know what possessed you to ask a question about Yamaha XS's on a Honda SOHC site when I can think of at least 3 websites devoted to the XS650.
Second of all, I'm disgusted that you decided to chop a rare bird like the XS1 when you can get '79-'83 Specials all day long for $800.
Thirdly, whilst your unique grasp of the English language would have doubtless proved hours of entertaining reading, I can only surmise from your punctuation and grammar you are clearly an inbred, toothless asshat.
Ta ta, Mooseknuckle.
