This is an original Service Manual for a 1976-77 Kawasaki KZ650-B1 (printed June 1976).  There are 114 pages of photos and detailed information.  This manual is NEW and does have signs of shelf wear on the outer cover.  The inside looks like it has never been opened.  These are ORIGINAL books and NOT a reproduction.  Great part for your vintage Kawasaki collection.
