Yes, we use the stock 35 chain and sprocket. You have to bend the frame where the rear fender mounts about an inch to get a predator to fit. Not sure if you will have to bend if you use the mount plate but I'm also not sure that you will have room for that plate. We drilled new holes in the original mount plate. If you can not use the plate make sure you have the engine exactly where you want it before you drill your holes. If your predator has a center fill gas tank make sure you have room to get the cap on and off with the new engine plate because it is very close to the top frame on ours,you almost can not get it on and off..
