Engine Tech Billet M9 big bore kit, Arctic Cat M7/F7 700CC to 900CC and I think you can do a 600 with 700 power valves, includes 2 billet cylinders with sleeves, 2 pistons, 1 billet head with inserted 15:1 domes and new O rings. I ran this set-up at 7500' and above with 30% av gas. Kit has about 400 mi on it or less than 4 rides. 185 HP with the jaws twins and Boonedocker box. Very stong runner! Also have jaws high altitude twins with stingers for the big bore kit and Boonedocker box that was recently updated. I know I have about $3400 in all of it, looking for best offer! Thanks Send a PM for any more details.
