Are they grooming? It was brutal the other day, and we are heading up on Thursday....are they still grooming or are they done already?

Well you can forget about the North East Carry, they decided that the season should end so they are stopping grooming this Sunday.

Millinockett is a great place to ride. As for that time of the year the season has generally past. I would probably pack some boots for the mud...... my opinion. 

Dont know the history on your sled. Are you the original owner? My two guesses are.... your not the original owner and the motor has been rebuilt before. If you have good compression.....run it.

No worries....my 07 did the same thing. First couple hundred miles and they looked like they were about half way worn thru. Rode the rest of the season about 700 miles never wore any more. The 121 sc4 has alot of pressure in that spot. They wear in quick there, then level off. As for the 137 sc4 seems to wear even.

had a problem with mine its an xtx 5250. sled was stalling after about 50k's ride time and hard to start would creep forward when started again. i believe the belt was not adjusted properly as it works fine now with a thinner one. I think i'll try one again and adjust belt defl;ection properly so the track isn't spinning.

Thats a belt deflection problem....not the belt. Do you not know how to ajust your secondary to get proper deflection?
Just saw some other members helped you out on  another thread how to set belt deflection....good luck.
