Bill Gately was the one who convinced me to go with the Wiseco pistons over the 11.5 and 12 ones available. I would have gone with a different piston for sure if I had known. I brought up the possibility of a class action suit on the other forum. I know we have enough people with the 904 to make some noise. The more I think of it, the more it kind of aggravates me. Wiseco should be a company that does it's research and development, why didn't they catch this long ago? Or maybe they did and hoped nobody else would.
