I have a Polaris outlaw 525 irs that I had built. I have the thumper big bore 99mm cylinder with the high compression piston from thumper racing. I have a little port and polish done to the head with the 807 cam in it. I also had kbr racing put a 80mm crank in it and the carb is punched out to 41.5 with the jd jet kit in it with the red.needle and the big o ring. I am looking for a stock motor and carb and $1200 for trade. Hit me on my email
