I dropped 3 valves and basically destroyed my 08 yz450 engine from the cylinder up. With me doing all the work myself, it was still going to cost about $1800, so I kept looking and looking, and finally found this 07 yz450 for what I thought was a hell of a good deal for $2000. So now I have all kinds of extra parts. I will probably be posting the suspension up for sale(Euro suspension set up for about 240lbs front and rear). After market parts are full fmf exhaust , full Euro racing suspension , boysen quick shot on carb, ride engineering triple clamps, the valves recently checked, blue hammer head shifter and engine plugs , just rebuilt and it has about 10 hours since then, new renthal R1 chain on plus a blue renthal rear sprocket and a new front only rode once with these and also a new twin air air filter. It also has a polished frame and swingarm. Here is my old one. I am going to combine the best of both onto one.
