hit up Jeff at fast racing! he will hook you up. I had him do a agressive dune port for a 4mill , I run rocket r2 pipes 35mm carbs, it's a power house you'll love it.
you have plenty of motor for ice racing stock! you need a swing arm 2 to 3 inches shorter than stock to get it to hookup on the ice.
my ported blaster would run circle around my shee on ice.
