I have no idea how I did it but the upper fork tube (brake side) is tweaked on my 2006 YZ250 and it needs to be replaced. I found a complete set of 2006 YZ450 forks on ebay that I can buy cheaper than buying just a new upper tube and I might go that route. Couldn't find just the 2006 upper fork tube online anywhere. Thought I'd check to see if by some super-slim chance anyone might know of anyone having an upper fork tube laying around for a 2006 YZ250 (crazier things have happened I guess ) The part numbers for the 2005 and 2007 are different than the 2006 part so I'm locked into needing the 2006 part. Oh...Thanks to Parma Dave for locating the slight tweak that was causing my front forks to feel like crap.
