I have 2008 Arctic Cat M8 Sno Pro and have talked to some riders with the 2009 and newer version of the same sled. They have said that it feels much lighter and is a lot easier to ride when boondocking. I know that they are just over 20lbs lighter but I have also heard that you can make some changes to the 2008 to make it carve and lay over like the 2009s. If I wanted to make these changes what would they be?
