i am about 500 miles away form hitting 70K miles on my 03 SB. I am 21 and tend to floor it more often than i should but was just wondering, what components, engine, suspension, cosmetic, should i be worried about taking a **** on me?????.

my dad once told me to never go by the "manufacturers" recommended change intervals and to always check your own on a regular basis

BTW, amsoil full synthetic 5w-20 w/ ~7500 miles , recently had trans rebuilt april of 2011
