hey all. new to forum. didn't see a way to search the forum and apologies if this has been gone over. my daughters grandparents just got her a new kfx 90. pretty sure it's a 2020 model. wanted to get a line on how to add a reverse gear to it since it doesn't come with one? I see a lot of the 90s are made by kymco and Arctic cat has one that has reverse. didn't know if it was as simple as a drop in kit or if I need to scavenge off another 90? I guess it may not be as simple as changing the clutch in the cvt?
