I have a 2005 RMK 900 with a 159.Asking 5200 OBO. It has 1600 miles on it. Strong running just had to replace a piston, but while i had it apart i replaced the other piston and put in all new gaskets. No miles on top end yet. This sled has many extras on it such as: Slp single pipe and can, slp air box, slp torque and push arm, every slp flow rite vent, 2 in. handle bar riser.
