Dalton kit in St.Anthony ?

Has anyone had any issues pulling proper rpm with a dalton kit on a stock 2014 two seat? We were down there end of July and I could not for the life of me get this thing to pull proper. My setup was as per the instructions and was super low rpm(7400 ish) so I kept on taking set screws and finally the rivet out to a totally empty weight and still couldn’t get it to pull (7900 ish).
My rzr is stock/dalton with a set of sand drifters with venomous rims and doors and roof so not a whole lot of added weight. Rzr had 22 miles on it at the time .
