well I never had much noise from the BB but after all the discussion decided to change the oil. my oil was black but not the gooy stuff some have had.--there has to be an easier way to change oil than pull the seat back and plate behind. I used my quick- lift but can only get the front wheels so far up, enough to slide under, but still see no way to fill the BB without removing the seat back and panel. It's changed and I don't have to worry if there is black goo or nothing at all in there.
