I have been reading and following the 880 and the 872 threads and I do believe that they make power over stock sled, I have been modding sleds for years and at the end of the day the stocker will be riding and making it the same places as me (maybe not as easy but makes it) watching the vids and reading these threads gives me the itch, but I promissed myself to truly give a stocker a real good chance, I just made the change back to doo since my 07 rev (which I loved) and now on a t-3, the sled seems pretty strong right out of the box if there is some good setups to dial in a stocker (clutching gearing) I would appreciate the info thanks
Dynamo Joes set up works very well for me on the 800 and my girlfriends on her 600 as well. Great upshift as well as backshift.
Dragging 660 in loose snow it is consistently 2 to 6 sled length ahead of stock clutching ( depending on how you come of the line) . In the powder it back-shifts smooth as butter just pins the rpm where you need it.
