Could someone explain how the different displacements are achieved? What are the changes necessary to modify a 2009 250 to a 450 or 510? Are the cam profiles and valves the same? My name is Thom Seivert I live in Placerville Ca. ride a 93 WXC 350 and a 2009 TE 250. Thanks for the effort gone into this site.
Welcome Thom, thanks for the kind words. I moved your post from the office into the Main forum where more people would find it
