I'm looking at a 03 CRF 450R and I am jsut curious as to what things I should check on it and watch out for. I am not new to dirtbikes so I know the usual stuff like tires, chain, sprockets, breaks all that stuff. Im wondering what specific things to a 450 do I need to be aware of? It has a Carbon Fiber White Bro's silencer on it, renthal bars, white bro's graphics and after market lower triple tree clamps. The valves have always been kept in adjustment but there is no record of the top end being redone. Is this a worry? If the top end hasn't been redone should I plan on throwing a piston rings and head job in as soon as I get it? Any help is greatly appreciated.
