    i am looking for some words of wisdom
    i picked up 2004 fatboy FI that the owner told me he just changed the oil.
    i rode it about 300 miles before the snow. it currently has 6700 miles on it.
    the original owner told me he changed the oil before and after the season.
    should i change the oil now, or wait till spring?
    also, is it ok to switch to full synthetic?
