In looking at the new Axys promo from Polaris they state they have a "New Grooved Piston for improved durability". The piston seems to be grooved only on one skirt just below the rings. It seems to me that the grooves are probably on the major thrust skirt of the piston as the minor side rarely has issues. It seems to me that the grooves would work good for holding waste material when scuffing takes place and reduce friction/seize. If so isn't this a patch not a solution?
