That's just a mock up. I run alot smaller sprocket then the one in pic. I wasn't 100percent sure this would work. didn't have time to mess with quad tonight. So I grabbed extra stuff laying around. Also ltz400 sprockets work . Lots of those out their. But this a 42 tooth in pic. So I wouldn't do this if you have as big or bigger then it. 42 still might work will check.
