【SP武川 01-05-0581 Hyper e-Stage N-15 Kit 143cc Big Throttle Body GROM Bore Up Engine Parts Takegawa】
■Product Description
The Hyper e-Stage N-15 Bore Up Kit includes the e-Stage N-15 Bore Up Kit, FI-CON TYPE-e (injection controller), and a spark plug.
The Big Throttle Body specification also includes a Big Throttle Body Kit.

■Detailed Description
●e-Stage Bore Up Kit 143cc
This bore up kit increases the displacement from the standard 124cc to 143cc by replacing the cylinder and piston.
When installed with the FI-CON TYPE-e (injection controller), it achieves torque-rich output characteristics different from the stock.
The cylinder uses the same steel cylinder as the stock.
Black painted. Uses a cast piston.
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 maximizes the performance of the stock cylinder head.
When installed, the Sports Camshaft (N-15) will be a decompression specification.
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 can deviate significantly from the ideal, so it is necessary to correct the fuel injection time with the FI-CON.
It can be installed simply by unplugging and connecting to the genuine ECU coupler.
FI-CON TYPE-e comes with multiple data settings adjusted by SP Takegawa for 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 increase up to 5000μs and decrease 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.
●Big Throttle Body Kit (with connecting tube)
Kit composition: Big Throttle Body Kit for normal cylinder head includes connecting tube for Big Throttle Body (connects to normal air cleaner box).
Maximizes the performance of the normal cylinder head and achieves high output.
You can enjoy engine characteristics that rev smoothly up to high RPMs.
Big throttle body bore diameter: φ34
The Big Throttle Body Kit includes the Fuel Injector ASSY. (00-00-0487).

■Notes
※Images are for illustration purposes only. Includes products of different sizes and colors.
※Product designs and specifications are subject to change without notice. Please be aware.
※By installing SP Takegawa e-Stage bore up kit, engine output and torque will significantly increase, thus increasing the load such as twisting and deflection on the crankshaft. SP Takegawa recommends installing a crankshaft support adapter simultaneously to reduce the burden on the crankshaft.
The crankshaft support adapter enhances crankshaft durability by adding support with a ball bearing at the crankshaft flywheel end, suppressing twisting and deflection.
※This product is made to order, so cancellations after ordering are not possible.
※This is a made-to-order product, so delivery may take some days. Also, please note that the manufacturer may discontinue or change specifications without prior notice. Thank you for your understanding.
