In the parts breakdown for my 2012 M1100T SP Limited, the lower driven gear is 38 tooth with a 84P chain. The 2013 shows a 49 tooth lower gear with a 90P chain. That would be a difference in final drive numbers. 1.81:1 versus 2.33:1? WTF! Can I use the 2013 lower gear and chain? In theory... this should gear it down?
