handlebar risers

I got a 04 grizzly 660, I use this quad for everything from farm work to hard woods riding, I find myself standing up most the time when I ride, I’m wondering if the rox 5 inch handlebar risers and fly bars will work with stock cables? Also while I’m at it I want to put handlebar warmers on, I want to keep the stock size grips and don’t want a big ugly throttle? What do u guys suggest
