【SP武川 01-05-0148 e-stage α Bore Up Kit 143cc GROM MSX125 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 a 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.
When installed with the FI-CON TYPE-e (injection controller), it achieves powerful output characteristics different from the stock.
The cylinder is made of steel, similar to the stock.
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-level models. It improves output performance with an optimal profile that brings out the potential of the stock cylinder head.
When installed, the Sports Camshaft (N-15) will be a decompression specification.
The N-15 cannot be assembled with genuine decompression parts.
●FI-CON TYPE-e (Injection Controller)
When installing a sports camshaft or muffler parts, the air-fuel ratio will deviate significantly from the ideal, so it is necessary to correct the fuel injection time with the FI-CON.
It can be installed by simply disconnecting the coupler of the genuine ECU and connecting this unit.
The FI-CON TYPE-e has multiple data sets pre-configured by SP Takegawa for SP Takegawa engine parts, so you can easily select, change, and adjust the settings using a PC or smartphone to match your engine specifications.
The injection time can be increased by up to 5000μs and decreased by up to 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 PC or smartphone, which is very convenient for setting adjustments.

■Notes
*Images are for illustration purposes only. Includes products with different sizes and colors.
*Product design and specifications are subject to change without notice. Please understand.
*By installing SP Takegawa's e-stage bore up kit, engine output and torque are significantly increased, which puts more strain on the crankshaft in terms of twisting and deflection. SP Takegawa recommends installing a crankshaft support adapter simultaneously to reduce the burden 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 increasing crankshaft durability.
*This product is made to order, so cancellations after ordering are not possible.
*Due to made-to-order production, delivery may take some time. Also, there may be cases of sudden discontinuation by the manufacturer or specification changes without prior notice. Please be aware of this beforehand.
