High Flow Oil Pump +50% - 2021+ Honda Grom/Monkey (5 Speed)

Yuminashi 50% High Flow Oil Pump

When upgrading to a high compression piston or a big bore kit, the key downside is that the engine temperature naturally increases with the added compression and performance. This +50% High Flow Oil Pump is great upgrade to help reduce those temps. The stock oil pump rotor comes in at 10mm wide and the Yuminashi pump comes in at a large 15mm size rotor. This is a great upgrade for even a stock build and is a very easy install.
