【SP Takegawa 01-05-0168 e-Stage α Bore Up Kit 143cc Monkey 125 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.
This product uses the stock throttle body.

■Detailed Description
●e-Stage Bore Up Kit 143cc
This bore-up kit changes the displacement from the stock 124cc to 143cc by changing the cylinder and piston.
By installing it simultaneously with the FI Con TYPE-e (injection controller), it achieves a torquey power output characteristic different from stock.
The cylinder uses the same steel cylinder as stock.
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. It improves power output by optimizing the profile to extract the performance of the stock cylinder head.
When the Sports Camshaft (N-15) is installed, it will be a decompression specification.
Genuine decompression parts cannot be installed on the N-15.
●FI Con TYPE-e (Injection Controller)
Installing a sports camshaft or muffler parts can significantly deviate from the ideal air-fuel ratio, so it is necessary to correct the fuel injection time with the FI Con.
Installation is possible simply by disconnecting and connecting the stock ECU coupler.
The FI Con TYPE-e contains multiple data settings set by SP Takegawa for SP Takegawa engine parts, allowing you to easily select, change, and modify setting data using a computer or smartphone according to your engine specifications.
The injection time adjustment allows for an increase of up to 5000μs and a decrease of up to 7500μs, making it widely available for everything 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, making it very convenient for setting adjustments.

■Notes
*The image is for illustrative purposes only. It includes products with different sizes and colors.
*The design and specifications of the product are subject to 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 will experience 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 to the flywheel side end of the crankshaft, thereby suppressing twisting and deflection.
*This product is made to order, so cancellations after ordering are not possible.
*Due to being made to order, this product will take some time for delivery. Also, without prior notice, the manufacturer may discontinue the product or change specifications. Please be aware in advance.
