I would venture to say yes. I am dealing with exactly the same problem on my 03 kx250. The outer basket is grooved on mine, but while I'm in there I'm changing all plates, springs and gasket. The basket is the most expensive.....normally about $200. I found a new Hinsin basket on EBAY for $129 and a kit with all plates & springs for $50 so a full clutch rebuild for under $200. If you've never. Performed a clutch rebuild before, take some advice I was given ......TAKE PICTURES as you go !!!!! It may save you a lot of time and those ohh so important $$$ 's.
