I'm getting a 79 xs650 in two days, and plan on getting what I need to make it run. Any recomendations on websites for parts or aftermarket parts? I'ts been in a garage for six years but still is in pretty good shape. Anything thing I should look for right away? I'm a bit new to bikes for building and restoring. Also, is it possible to "chop" the bike but retain a two passenger seat?
