I just blew my 2010 crf250. i bought all the parts i needed and a service manual. My dad used to race for factory KTM so he has a lil insight. but ive never torn apart a motor before and im afraid im gonna mess something up then have to pay even more. I have a guy that can do it for me but he says 40/hr for labor. Is rebuilding my first motor on this bike a bad idea?
