My buddy had a 2002 MM700 with a 151" track on it. It really ripped for a 700. I think the claimed power on those things was about 115 HP. All he had was a can, but it felt a lot stronger than 115 HP to me. I loved the sound and could tell his sled was coming from the next valley away. All he every did was put oil in the thing. I don't think I ever saw him change a belt.
sounds about right
i had a '01 MM700 with camo 144" a can and 2" risers, that sled took me anywhere i needed it and only maitnence was change oil and plugs every season.
of course it was also the meanest sounding sled on the mountain too
