Koso Super Flow Oil Pump - GY6

Koso's High-Flow Oil Pump (NF239000) for 125/150cc GY6 engines is strongly recommended for those who upgraded their engine with a Big Bore Kit. The addition of this high quality part will increase the oil flow by 20%, 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.
