Sorry but I did not get a owners manual with my 1980 Honda Express. Is the clutch wet or dry. I have no idea yet how the engine drives the rear wheel. So if wet how do we check the oil for the drive system? What type oil? I sent money for a CD owners manual on ebay and the freaking jerk never sent the manual to me. Also can anyone tell me how to block off the injector oil system and go to pri-mix?
