    Hey all I installed a slip on muffler and k&n air filter in my machine, I'm told I don't need to do tune however I would like to pick up the extra HP. Can anyone recommend preferably a plug and play tunner for this bike?

    This is my first ever forum posts so please bear with me... I have a 2019 Polaris sportsman 850 SP and I wanna upgrade the tires. I’m looking at 29’s but I don’t know if they will fit if I keep the suspension and control arms stock. I would not mind trimming some plastic but I don’t want to do...
