【SP Takegawa 01-05-0632 Hyper e-Stage Bore Up Kit 143cc Super Cub C125 Engine Parts Takegawa】
■Product Description
The Hyper e-Stage Bore Up Kit 143cc includes the e-Stage Bore Up Kit 143cc, a sports camshaft (N-15), a big throttle body kit, FI-CON TYPE-e (injection controller), and a spark plug.

■Detailed Description
●e-Stage Bore Up Kit 143cc
This bore up kit allows you to change the displacement from the stock 124cc to 143cc by replacing the cylinder and piston.
When installed simultaneously with the FI-CON TYPE-e (injection controller), it achieves powerful output characteristics that differ from the stock.
The cylinder uses a steel cylinder similar to the stock one.
Silver painted. Cast piston adopted.
Bore diameter 56mm. Compression ratio 11.2:1. Stroke 57.9mm (stock).
●Sports Camshaft (N-15) Decompression Specification
The Sports Camshaft (N-15) is a camshaft developed for entry-level models. With an optimal profile that brings out the performance of the stock cylinder head, output performance is improved.
When installed, the Sports Camshaft (N-15) will be a decompression specification.
Genuine decomp parts cannot be assembled with N-15.
●FI-CON TYPE-e (Injection Controller)
Since installing a sports camshaft or muffler parts can significantly deviate from the ideal air-fuel ratio, it is necessary to correct the fuel injection time with FI-CON.
Installation is possible simply by removing and connecting the coupler of the genuine ECU.
The FI-CON TYPE-e has multiple setting data pre-loaded by SP Takegawa to match SP Takegawa engine parts, so you can easily select, change, and modify setting data using a PC or smartphone according to your engine specifications.
The injection time adjustment can be increased by up to 5000μs and decreased by up to 7500μs, making it widely available for vehicles from stock displacement to bore-up vehicles.
It is equipped with monitoring functions for engine speed, engine temperature, throttle opening, and injector opening/closing rate using a PC and smartphone, which is very convenient for setting.
●Big Throttle Body Kit φ28
This product is an SP Takegawa original big throttle body that supports the stock air cleaner box/connecting tube.
While the genuine throttle body is φ24mm, the SP Takegawa big throttle body is φ28mm.
No processing of the cowl or wiring is required; simply replace it with the stock throttle body on the genuine vehicle to maximize the performance of the stock cylinder head and increase output.

■Notes
*Images are for illustration purposes only. Includes products with different sizes and colors.
*Product design and specifications may change without notice. Please be aware.
*Due to the significant increase in engine output and torque with the installation of SP Takegawa's e-Stage bore up kit, the crankshaft experiences increased stress such as twisting and deflection. SP Takegawa recommends installing a crankshaft support adapter simultaneously to reduce the load on the crankshaft.
The crankshaft support adapter adds support with a ball bearing at the end of the crankshaft flywheel side, thereby suppressing twisting and deflection and enhancing crankshaft durability.
*This product is made to order, so cancellations after ordering are not possible.
*Due to being made to order, delivery may take some time. Also, please note that the manufacturer may discontinue the product or change specifications without prior notice. Thank you for your understanding.
