I purchesed a RZR 800 on the 12th of sept and took possesion of it on the 14th brought it home parked it in the garage. I rode it 7 times around the block putting all of 10 miles on. When i toolk it out for a ride after work in my neighborhood the engine sounded funny so i took it in to Ride Now Power Sports in SUrprise Az where i bought it. I asked the lead tech as well as the General Manager to check it out, they started it and said it sounded bad. When they diassembled it the forund the engine was bad (A bad lifter) They advised me that all they could do is remove a motor out of a new unit and wait for the crate motor Poloris was sending the to replace the motor in mine. I advised them i wanted a new unit the say they are unable to do so, Polaris does not allow that because i have already titled the one i got from them. The customer service at polaris is advising me all they can do is fix the problem due to manufactures warrantys and will not give me a new unit... What is up with this? Brand new unit never been on dirt.. When i took posession of the unit it had 38 miles on it Ride Now is telling me that this milage is from moving the unit in and out of the store lot, when i bought it it was in the store not outside...... I feel i am being jerked around can anyone help??????
