Big Bore Support 3-Piece Set for 12V Monkey

The bore-up support kit is a recommended support kit that allows for "ignition characteristic changes," "increased oil pump capacity," and "cam chain strengthening" when increasing engine displacement.
By purchasing and installing it together with a Takegawa bore-up kit, you can maintain stable output and improve part durability.
The bore-up support kit is a value-for-money set that combines a Hyper C.D.I., Super Oil Pump, and Diehard α Cam Chain.
A miniature drill driver for orifice processing is included for Monkey models.
