Only for 2013-2020 Groms(OG & SF)/MSX/Monkeys
OEM Honda Grom oil pump. It has a relocated, press fit copper pick up tube that draws oil from the best possible location in the motor for wheelies and riding on 2 wheels. Just remove your unmodified pump and install the OEM SUP in its place with the tube passing through the smaller hole, into the center of the motor. You will need a high flow pump (Takagawa & Kitaco) if you have an oil cooler and/or a big bore kit. A high flow pump in a stock motor wont hurt the motor or pump. SUP recommends you only change the pump AFTER the "break-in oil change/clean out process" to help prevent the possibility of a clogged oil passage.
