install 135mm ski doo wheels on the two in front, both sides 4 total, (yamaha wheels are 130mm) install new hyfax, kimplex type. They are a little thicker that OEM, problem solved, I have 2 seasons on the same hyfax, over 14000 miles on sled total, this is the trick.
no my rails didn't break or bend.
130mm wheels--ZERO hyfax 3.5 mm difference
135mm wheels--New hyfax 2mm difference
IT WORKS!!!
