Just bought a 78 CB400A Hawk Hondamatic and I have NO idea of how to drive it... Is it a centrifugal type clutch just like a Honda scooter? i.e. If the revs go below a certain point does the transmission automatically "go" into neutral mode and coast until you again apply gas (like a car), or do I have to always shift into neutral to prevent stalling? Also when does one upshift manually into second (high) gear---just by sound, or at a certain speed? Many thanks!
