Hi to all, I have Xp 163 and I think to cut off my tunnel couple inches shorter because I noticed when my sled starts trenching it is really hard to turn because hard mud flup and long tunnel making sled hard to move and as soon as mud flup and rear handle on tunnel stuck in the snow track losses pressure and track starts spining freely.So I thinking to cut off tunnel little bit shorter and replace hard snow flup with a flexible snow flup anyone did this in the past.Thanks.
