since the HL500 is a bit rich for me and te610 rollers go so cheap ive had thoughts of putting one of my favourite yamie motors a tt500 into a 610 frame,so has anyone tried to do on this site?and whats involved other than making and welding new engine mounts?the big back bone should make a fine oil tank with a few mods,the airbox/carb is on the right side to join up and a hl shape header pipe would join up with the stock husky twin muffler exhaust as well.any thoughts fella's?
