I have a 2012 1000 that has sat idle for near three years. I’ve bought it new and have near 1500 miles on it. Decided to get it moving again! So I have installed a new battery and changed fluids. But it seems to be super doggy. When in high on the road I might top out at 45mph and was getting the codes for speed sensor and harness which would clear at lower speeds... I don’t think the belt is slipping due to the revs not even getting that high. Any advice would be appreciated!
