Thanks Graham472. I only found a couple of numbers on the forks. At the bottom on the inside of the fork there is a 271-P on one side, and a 271-L on the other. I looked on the inside of the white plastic fork cover which was designed for 01,02,03,04 models. RedfoxCR, I think it is a leak because I only get an oily residue buildup on one side.
