Well it seems like they fixed my sputtering problems after waiting a month and bringing it back 3 times to the dealer. They replaced 2 computer boards, one under the head light called the module engine controller and the other one was behind the fan called the module controller. They said it took so long because polaris documents everything they do and that can take time.The dealer calls polaris asking for directions ( EFI is new to everyone) and they respond we will get back to you . Also, they were slow on shipping out new parts. Keep in mind that my warranty had just expired by one month. And at $75 a hour working on the quad things could add up fast.. Polaris was great they gave me all the parts free, over $650. The dealer had invested over 8 hrs, they only charged me for 1 1/2 hrs. Thanks Joe and the gang at ledgewood !!!!!!!!!!! Well even know it took 3 trips and a lot of time, back and forth to the dealer , I am very happy that everyone work together to make the problem go away. IT IS VERY VERY IMPORTANT TO BY AMERICAN MADE QUADS AND CARS AND MOTORCYCLES !!!!! YOU CAN TAKE ALL THOSE IMPORTS AND PUT THEM WHERE THE SUN DONT SHINE!!!!!!!!!!!!! GO POLARIS SEE YA ,,,,,,,, RUSSKELL U.S.A.
