Shimming primary

So I purchased a wide ratio kit and I threw it on my 800 rzr-s. Upon startup the secondary was rotating and it would grind real bad trying to go into gear and I didn’t have the .20-.30 clearance between the outsides of the belt and the primary. I have add to add a crazy amount of shims to get my clearance needed between the belt and primary. Now when I torque the primary the rollers will not even sit on the flyweights. Can anyone help me out on what I am doing wrong? Any help is appreciated, thanks!
