Does anyone know where I could find the specifications of the aluminum used on the frame of a 2002 cr250? In particular, I need to know how thick the walls of the main spars are (i.e. .120" or .095" or ?) I'm considering buying one, but it has a couple grooves that appear very deep in the main spars of the frame and I'd like to see how close they are to going all the way through. I know this can be repaired, but I'd like to know what I'm getting into before I seal the deal.
