2002 600 RMK 144. This sled came from Idaho a year ago. I swapped out the 136 rails for 144 and took it to Wyoming for a week of riding and a few days of riding here at home last year.In the spring I rebuilt the motor from top to bottom with new seals, gaskets, pistons and a low mile crank. A week ago I spent a day in the UP riding. The sled runs very good. 240 miles on the fresh pistons. Sled currently has a 144X1.25 Switchback track off a 2007. I have a well used 2 inch paddle track, mountain weights and jetting that will go along for the asking price. Sled is not a showpiece. The bellypan has a nice protector but bellypan is cracked in several spots which is the way it was when I bought it. Has not affected a thing. All suspension mounts are fine. Trailing arms are fine. Seat is good. Hood has numerous scratchs from riding in the trees out west. Odometer reads 3400 +,-. Speedo quit on me last year. I pulled the 2" track to install the 1.25 this fall and replaced the inner chaincase seal while I could get to it. Drivetrain bearings all felt fine. Sled has 2010 Gripper skis off a newer RMK. Sled has very little corrosion as it was from out west and did not see much road salt. PM, Email, call or text for additional info. 319-240-5901 Cash only. Located in Waverly, Ia
