Well the yz250 sold for $2500 so I went and looked at the YZ400F
I talked to the owner for quite a while, started up the bike and road down the street. Being used to riding a street bike the 4 stroke felt really nice. I talked to him a little more about the bike and he showed me all the paper work for it and explained everything that was done to the bike. I could tell he liked the bike and took great care of it.
I'm now the happy owner of a yz400f and a few boxes of the stock parts that were replaced, chain lube, brand new sand tire, desert tank, extra stock rear tire, coolant, tiedowns etc. the guy hooked me up.
When I got home I cruised around in my backyard, got a little sideways and was in heaven :-)
Thanks for the feedback guys and thank you Scott for the great bike!
