I installed a 1.25 track on my 2000 mxz 700, it has 144 studs in it also. I put the track on 2 weeks ago and my sled has not run yet but I have the belt off and tried to rotate the track it was quite hard and there was some squeaking. Well yesterday I went to put a new snowflap on and I had a real good view of the tunnel from the back and I coul see my lugs were touching my tunnel protectors. What can I do? Everybody and their mother told me this track would fit,including the dealer. Are there different size tunnel protectors or what?
