The last time I ordered the 90441-259-000 copper washers they were superceeded by 90441-286-000 which are steel. I remembered an 8mm copper sealing washer on a CBR600 so I looked at the parts diagram and ordered them. They are 90442-028-000 and they are copper. The original copper washer on my bike measured out at 2.57mm, the steel washer was 2.33mm and this washer I just got from Honda is 2.29mm. I am zinc plating it now and will use those on the corners and the steel -286- on the inner 4 studs. Even though they are a little thinner than the originals I think they will work.
