Stock gearing for a 2003 CBR600RR is 16/43, and I'm re-gearing to a 520 setup 15/46. The chain I was told to order was a 110 link. Stock links are at 112. Is 110 too few? How many are too few or too many? Also, do I need to get a rivet tool or is there a "home improvement" approach to working with rivet style chains?
