The PO posted on here for a bit (Hey Kyle), and it seemed as though there were some...
So I just purchased my first bike ever. It's a 1981 xs400 special. The electric start button is broken so it's kick start only. Is there a procedure to start it? Iv been trying for hours to start it. When I bought it, the guy just kicked it once and it started. I don't get it. Sorry for the noob...
