Changing a 155" track to a 144" track or 146" track,

[arctic cat m8]

Hello I have a 155" track on a 2009 polaris rmk. 800 and was wondering if there's a way or what I'd have to do to make it a 144" track or 146" track? , as I never make it to mountains hardly ever anymore and like the 144" track better for the style of riding I do,

Sell it and buy a assault! It will really wreck it's already low resale value by chopping it up!
