Greetings. This is my first post on a winter sport forum and my first sled in nearly 40 years - god I am old. I have been a jet ski modder for decades: See: http://greenhulk.net/forums/showthread.php?t=262143&highlight=rxpxseadog Anyway, I just bought a new 2017 BTX SE and ride in the mountains of UT, WY and MT and trails (primarily Yellowstone). After buying this sled, I found the 1.75 track is simply too challenged by Guardsman Pass in UT (see photo) . While a 2.5/2.6 track would be an improvement, a 2.8 track would be a bit more helpful. Based upon measurements it appears the 2.8 track will fit, but just barely, perhaps by .25". This is quite a slim margin given the 2.5 lug will clear by .75+". My concern is slapping against the tunnel given the minimal clearance. Any help or thoughts or experience would be greatly appreciated. Thank you.
