i just purchased a 78 tomos A3SP and am working on getting it cleaned up and running smooth after what appears to be a bit of abuse by the previous owner. i'm currently changing the fluids and i'm wondering how much and what kind of oil goes in the transmission. a couple of other posts mentioned both type f and regular 10 w 30 motor oil. i would appreciate any advice given. this is my first moped and i want to do it right.
