Hi!
Now I´ve been to my garage looking for answers. #388/407 castdate 4/6 small pad, #609/636 castdate 4/19 small pad, #849/864 castdate 4/10 small pad, case 805 castdate 5/6 big pad, #1266/1216 castdate 5/12 big pad. I saw a bike one year ago with an enginecase and small pad just above 1000, 1009 I suppose. The bike mentioned above has enginecase 970 and big pad. Interesting to find out if there is a system for small or big pads. My only ideea is that Honda has sent some stamped enginecases as warranty while chainbreaks or something else.
Regards, Bo
