2006 crf450x trade toward a on/off road

2006 crf450x Pretty well mint Last year I was having a hard time starting it so I put a new cylinder, piston, rings, valves and a carb off a 450r. All the parts are new OEM Honda. Works great. Ive put 2 or 3 tanks of gas thru it since rebuilding it. New front tire, back about half, new chain and sprockets, new brake pads and rotors,Lexx exhaust,, nothing at all wrong with it, if I can't make a deal on an on/off road I'm just going to buy the kit to switch it over to blue papers and make it street legal
