I recently bought a brand new 03 MXZ. 0 miles from a dealer. Finally got the chance to ride last weekend and it was great. Broke the motor in on Sat. then let loose on Sun. Beautiful riding on Mt. St. Helens. Only one problem. The sled is suppose to have reverse, but I couldn't get it to engage. Any tricks? I followed the instructions and even had an experienced ski doo rider try to engage it with no success. Any easy fix before I run it in to the dealer? I want to ride not wait for the sled to get outa the shop.
