I recently bought a cobra fi2000r fuel programmer from motosport for my 2008 sportsman 800. I installed this on my machine and I loved it. The top end power was amazing. To install it all it took was to take the front box off and plug in 2 connectors and a ground. Unfortunately I just wrecked my Atv via maple tree. And I no longer need this because I'm buying a 850xp. Any and all offers considered. Only thing wrong with it is I broke. the cover for the dials. The cover was not water tight so it should be the same without it. It does come with original packaging and instructions. It says it fits 2005 and up sportsman 700 and 800s.
