Hey guys. Was wondering when its time for a new bottom end, and if anyone had done one. Im a trail rider and never at any sort of track, so most of my riding is low rpm (usually below half throttle), with the occasional WOT passes through a field. What gets replaced typically? Just the bearings or the whole crank assembly? I ordered all my top end parts off of the TT store a few minutes ago, so while im in there this weekend (or next), what should I look for?
