Original Honda manual not a reproduction
Pictures are for a CL160 but engine specs, other than possibly one extra tooth on a countershaft, would be the same for a CB160 Otherwise nearly new condition. Lots of pictures diagrams and a complete wiring diagram. This is must for tuneups.
Dated July 1966, one 1/4" pen mark on the rear cover, and VERY slight discoloration on the edge of the binding, otherwise excellent condition
