Yeah it was ridden but I think most the wear came from sitting in the guys garage for 15 years.  Its been so long since I have owned a 250 what are the spots on the frame that should be strengthened up  If I remember right there are a few spots that I can have someone weld some gussets.  I usually walk around between 210-225 pounds and this is probably pretty taxing on the old girl so if I can add some strength now and keep it riding straight then now is the time to do it.  I just don't want my fat ass ruining this bike before my kids get a chance to.
