Hyper e-Stage Big Bore Kit 143cc CT125 Hunter Cub

【SP武川 01-05-0641 Hyper e-Stage Bore Up Kit 143cc CT125 Hunter Cub Engine Parts Takegawa】
■Product Description
The e-Stage 143cc is a light bore up kit that allows you to enjoy increased displacement and power at a reasonable price.
Furthermore, by adopting SP Takegawa's big throttle body, it achieves powerful output performance not found in normal engines.

■Detailed Description
●e-Stage Bore Up Kit 143cc
This bore up kit allows you to change the displacement from the normal 124cc to 143cc by changing the cylinder and piston.
By installing it simultaneously with the FI-Con TYPE-e (injection controller), it achieves powerful output characteristics different from the normal engine.
The cylinder uses a steel cylinder similar to the normal one.
Black paint. Cast piston adopted.
Bore diameter 56mm. Compression ratio 11.2:1. Stroke 57.9mm (normal).
●Sports Camshaft (N-15) Decompression Specification
The Sports Camshaft (N-15) is a camshaft developed for entry-level models. It improves output performance by optimizing the profile to bring out the full potential of the normal cylinder head.
When installed, the Sports Camshaft (N-15) will be a decompression specification.
Genuine decompression parts cannot be assembled with the N-15.
●FI-Con TYPE-e (Injection Controller)
When installing a sports camshaft or muffler parts, the air-fuel ratio can deviate significantly from ideal, so it is necessary to correct the fuel injection time with the FI-Con.
The FI-Con TYPE-e has multiple setting data pre-installed by SP Takegawa for SP Takegawa engine parts, so you can easily select, change, and modify setting data using a computer or smartphone according to your engine specifications.
The injection time adjustment ranges from a maximum increase of 5000μs to a maximum decrease of 7500μs, making it suitable for a wide range of vehicles from normal displacement to bore up vehicles.
It also features monitoring functions for engine speed, engine temperature, throttle opening, and injector opening/closing rate using a computer or smartphone, which is very convenient for setting.
It can be used with all SP Takegawa products (for CT125) from normal displacement to bore up kits.
●Connects to genuine ECU with coupler
Since the controller wiring uses a coupler compatible with the genuine ECU, no wiring modification is required, and it can be installed by simply connecting the coupler to the genuine ECU.
●Big Throttle Body Kit φ28
This product is an original SP Takegawa big throttle body kit compatible with the normal air cleaner box/connecting tube.
Compared to the genuine throttle body of φ24mm, the SP Takegawa big throttle body is φ28mm.
By adopting the SP Takegawa big throttle body and manifold, it can be connected to the normal connecting tube, so the normal air cleaner box can be used as is.
No modification to the cowl or wiring is required; by simply replacing the normal throttle body on the genuine vehicle, the performance of the normal cylinder head can be maximized, and output can be increased.

■Notes
*The image is for illustration purposes only. It includes products with different sizes and colors.
*Product design and specifications are subject to change without notice. Please understand.
*Due to the significant increase in engine output and torque when installing the SP Takegawa e-stage bore up kit, the crankshaft is subjected to increased stress such as twisting and deflection. SP Takegawa recommends simultaneously installing a crankshaft support adapter to reduce the load on the crankshaft.
The crankshaft support adapter enhances crankshaft durability by adding support with a ball bearing at the end of the crankshaft flywheel side, thereby suppressing twisting and deflection.
*This product is made to order, so cancellations after ordering are not possible.
*As this product is made to order, it takes time for delivery. Also, please note that the manufacturer may discontinue or change specifications without notice. Thank you for your understanding.
