If you notice wear marks on the inside leg of your fork slider it is being hit by the fork guard. The remedie for this is to remove the nylon ring off the fork and replace it with fork guides from a 99 250 two stroke. They must be modified. All protrusion must be removed and ground smooth with a angle head die grinder with a sanding pad attachment. The inside band should be reduced to 12 mm so that the new guide will fit in the grove in the fork. A sharp wood chisel will do a good job of reducing the band to 12mm by scrapping the materal off the buttom of the band.
