Thanks for your reply. I use Motorcycle Castrol Racing 10/40 fully synthetic. It is my impression that whatever oil is used oil should not make contact with the clutch otherwise it slips and burns, but I might be wrong. Maybe you mean the gearbox? The oil ratings from when Honda produced the Blackbird have improved somewhat. Mine seems to be going fine. Thanks again.
