Not that I know of. This does have a very stout forged piston, unlike the sand cast ones in the 400/450s. This piston is one of the reasons this bike seems to run forever. I have seen '02s with who knows how many miles on them and just beat to crap and then pulled out and ridden some more. Tough bikes. Just raise the deck height a bit with thicker base gaskets.
