There is alot of rock and cliffs in Deadwood area. Jetting:YES, clutching:NOT always. (check with dealer) I ask my dealer for a jetting chart for every Carbed sled I have. They can get it off there computer. It is not always in the owners manual. Older Polaris sleds have this info on the underside of the hood. Clutching a newer Doo is a cake walk. Polaris is much more work. Not sure about the rest.
