The lower fork tube on my '97 yz 250 is dented the dent is on the lower tube and is about 2/3 throught the travel. The dent is 1/16 of an inch deep and 3/4 wide at a 90 degree angle with the tube. Should I replace this - I'm thinking I should although I'm not sure how long it has been like this. I use this bike for trails only. Does anyone know where I can find a replacement and how much that will cost?
