Hey everyone im new here but not so new to a bike. I have a yz 125 that I need to replace the bottom end on ( crank connecting rod, all bearings and gaskets) so a bottom end kit. Also I happen to have an 09 crf 250r now I don't want to sell the bike I want to fab mounts for a cr 250 or 500 motor. So my next question is does anyone happen to have a cr250 or 500 motor. thank you all for your time and input and info or website will help.
