after how many times the bottom end on a 400ex should be rebuild before a broken rod or crank bearing was gone?? mine is a 1999, i never rebuild bottom end, run stock for 2year, 416 1year and 426 for 1year, i see a lot of broken rod on the forum so it make me nervous about mine, what do you think??
