Engine runs well as expected be sure if you are putting this in a ssr 170 utv to buy the shifter lever that fits this motor the factory lever will not work I took the lever out of the old motor I had and used it (requires some mechanical skill and don’t recommend if you are not mechanically inclined it requires you to pull the transmission cover off) also the wiring on the stator plug and shift indicator plug are not the same soo I used the old shift indicator off of my old motor and then had to splice the wires on the new stator on to the old plug from the utv
