2000 125 2005 125 any one know the differences between the 2 ?I have the chance to pick up a 2005 kx125 motor, pipe, carb, cdi, localy . would a 05 motor fit in place of a 2000 motor easily? possibly better low end? gear ratios about the same? I don't want to hear about suspensions etc as I,m going to stuff it into a kx100 frame , i have already done this swap once on a 2000 100 frame and a 2000 125 motor so would it be about the same build is what I,m wondering ?
