Ok folks - need your help. Prepping the bike for the MABDR ride come spring. Need to understand how the OEM sprockets and chain hold up. At what mileage did most of you need to consider changing out the OEM components. Mine looks ok now with 3.5K but will most likely have over 5K miles on the bike by the time I'm ready to depart for the MABDR which will be a 2.5K round trip excursion. I'd like to also upgrade the sprockets/chain to something with more longevity - would appreciate suggestions on that front as well.

Thanks in advance.
