I'm a newbie so please be nice to me lol!! I am also not a sled mechanic so please be patient with me. I'm so glad I found all you Arctic Cat F1000 onwers!!! I just currently purchased a 07 sno pro F1000. After reading all of your discoveries of all the problems you guys have been having I'm kinda dissapointed. I could have bought any new sled out there but choose to stick with my Cat. Is there a new reflash out there? I noticed when I let my sled warm up that it really smokes and you go to take off it is all boggy and spits and sputters. It only has 200 miles on it and I know that the dealer put 100:1 mix in the tank. Just kinda wondering if that fouled the plugs. I need to check them. Whats the main differnece between the 07 and 08? So if your exhaust melts your plastic is it under warranty? Thanks a lot guys.
