right now my 80 is all stock, but i'm tearing down the engine to put new pistons/rings and gasket set in. i was gonna measure the squish beforehand, and maybe get the heads cut. i'm looking for a set of pipes that make someadditional power, but dont sacrifice it's dependability. also looking for carbs that do the same. just want to make a little more power without sacrificing what the sled already is. nice 2 ride and dependable
