My name is joesoef from Indonesia..
did you have service manuals or wiring diagram for Honda CB77 superhawk or CYP77 and also 1961 Matchless G3 350cc
I don’t have them on hand. I get a dozen manual requests every week and try to keep up as best I can. I do have a new batch of about 40 manuals I need to get posted, but your bike isn’t in that group. I’ll see if I can dig up anything for you. thanks for reading.
