    Hello Peter,
    You are clearly correct. It is some years since I actually read the Supa5 spec, and obviously my memory must have been playing tricks about the mains. Your explanation for the difference seems extremely likely, so thanks a lot for clearing it up.

    Thanks again for taking the trouble to consider the question, but I am still hopeful somebody on this website will know the answer before looking further afield.

    Thanks, Ian for taking the trouble to reply, but I am seeking info specific to MZs and the Supa5 in particular.

    My local bearings trader says C4 mains are Ok for modern Jap motorbikes and would *probably* be OK for an MZ.

    The internet has a lot of information about bearings in general, but nothing about what to use in an MZ.

    I agree it is wise to follow the manufacturers recommendations, but these have changed for what are essentially very similar engines. Why?
