We have found that many riders do not adjust their tracks properly when installing the M series models. The 2 ply deep snow tracks with high lugs should not be run loose. Adjust to the factory specs and even a tad bit more will not hurt. This will keep the track from oscillating at certain speeds, make better contact with the drive sprockets, and improve overall efficiency and performance.
High Speed: M tracks have heavy, deep lugs that create a lot of momentum and force when spinning at higher speeds. Running down hard pack or icy trails at high speeds can cause lugs to separate from the belt. To insure the best life of your deep snow track it is recommended to keep speeds down in these conditions to a maximum 70 mph on 2.62" lug models and 60 mph on 3.00" lug models.
