Koso High-Flow Oil Pump (NF623000) for the Honda Grom and Honda Monkey (2014-2020) is strongly recommended for those who upgraded their engine with the Koso 170cc Big Bore Kit and 4v Cylinder Head. The addition of this high quality part will increase the oil flow by 40%, which is a very effective modification that will help prevent engine failure. Keeping the engine lubricated and cool is very important, whether you ride for fun or for races.
