I have a BMP 800 big bore kit for Arctic Cat M6, M7, F6, or F7 sleds. Everything is new and never been installed. I have the cylinders, pistons, powervalve spacers, billet head with inserts, y-pipe, pipe, and canister. I have too many projects and it has just been sitting on the shelf. I would be willing to take a F7 top end in on trade towards it. Everything I have sells for over $3000. I am willing to sell it for quite a bit less than that to move it. Feel free to call me at 612-490-5696 anytime with questions. Thanks, Matt
