Does it work?
Hiya Vando, when you say you have it back together, but have a doubt,do you mean you have or have not tried to use the bike yet?
My best guess is that the 'polished' or 'used' side has been in contact with the clutch plates. I shouldnt think it would make a lot of difference which way you put them...... when I stripped mine I cleaned them all up in Kerosene to check, then just reassembled them in the same order but not really taking any notice which way round they were..... and my clutch works just fine.
i think you will be OK, but opinions may vary.....
