eStage α Bore Up Kit 143cc GROM

[SP Takegawa 01-05-0160 e-stage α Bore Up Kit 143cc GROM Engine Parts Takegawa]
■Product Description
The e-stage α bore up kit includes the e-stage N-15 bore up kit, FI-CON TYPE-e (injection controller), and spark plug.

■Detailed Description
●e-stage Bore Up Kit 143cc
This bore up kit changes the displacement from the stock 124cc to 143cc by replacing the cylinder and piston.
By installing it simultaneously with the FI-CON TYPE-e (injection controller), it achieves powerful output characteristics unlike the stock one.
The cylinder uses a steel cylinder similar to the stock one.
Black paint. 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 models. It improves output performance with an optimal profile that brings out the performance of the stock cylinder head.
The Sports Camshaft (N-15) will be a decompression specification when installed.
Genuine decompression parts cannot be assembled to the N-15.
●FI-CON TYPE-e (Injection Controller)
When installing a sports camshaft or muffler parts, the ideal air-fuel ratio will deviate significantly, so it is necessary to correct the fuel injection time with FI-CON.
Installation is possible simply by disconnecting and connecting the coupler of the genuine ECU.
FI-CON TYPE-e has multiple data sets prepared by SP Takegawa to match 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 can be increased by a maximum of 5000μs and decreased by a maximum of 7500μs, making it suitable for a wide range of 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 computer or smartphone, which is very convenient for setting adjustments.

■Notes
*Image is for illustration purposes only. 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 with the installation of SP Takegawa's e-stage bore up kit, the crankshaft will experience 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 ball bearing support to the end of the crankshaft flywheel side, suppressing twisting and deflection and improving the durability of the crankshaft.
*This product is made to order, so cancellations after ordering are not possible.
*Due to being made to order, this product takes time to deliver. Also, please note that the manufacturer may discontinue the product or change its specifications without prior notice. Thank you for your understanding.
