Hyper Tuning Set with Big Throttle Body for GROM

【SP武川 01-02-0035 Hyper Tuning Set with Big Throttle Body for GROM Engine Parts Takegawa】
■Product Description
This Hyper Tuning Set allows for increased power output by replacing the piston and camshaft without changing the displacement, and simultaneously installing the FI-CON TYPE-e (injection controller).

■Detailed Description
●High Compression Piston Kit
Through an optimal balance of piston shape and compression ratio, this kit delivers high power performance unmatched by other manufacturers.
By replacing the piston, while maintaining the Monkey 125 (JB02) displacement and using the stock cylinder head and cylinder, power output can be increased.
This piston was meticulously designed to achieve higher compression, higher combustion efficiency, and lower friction, pursuing an optimal piston shape.
High-rigidity forged aluminum is used to withstand higher compression ratios.
Bore Diameter: 52.4mm (same as stock bore diameter)
Compression Ratio: High-compression piston 12.5:1 (stock piston 9.8:1)
*Requires high-octane gasoline.
●Sports Camshaft (N-15) Decompression Specification
The Sports Camshaft (N-15) is a camshaft developed for entry-level models.
It improves power 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-less 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 will deviate significantly from the ideal, so it is necessary to correct the fuel injection time with the FI-CON.
Installation is possible simply by disconnecting and connecting to the stock ECU coupler.
The FI-CON TYPE-e comes with multiple data sets pre-configured by SP Takegawa to match SP Takegawa engine parts, allowing for easy selection, modification, and adjustment of settings via a computer or smartphone to suit your engine specifications.
Injection time adjustment allows for a maximum increase of 5000μs and a maximum reduction of 7500μs, making it suitable for a wide range of vehicles from stock displacement to bore-up vehicles.
It features monitoring functions for engine speed, engine temperature, throttle opening, and injector opening/closing rate via a computer or smartphone, which is very convenient for setting adjustments.
●Big Throttle Body Kit (with Connecting Tube)
Kit composition: Big throttle body kit for stock cylinder head, and a connecting tube for the big throttle body (connects to stock air cleaner box) are included.
Maximizes the performance of the stock cylinder head and achieves high power output.
You can enjoy engine characteristics that rev smoothly up to high RPMs.
Big Throttle Body Bore Diameter: φ34
The kit with the big throttle body includes the Fuel Injector ASSY. (00-00-0487).
●Regarding the installation of the High Compression Piston Kit
The installation of the SP Takegawa High Compression Piston Kit significantly increases engine output and torque, which puts more stress on the crankshaft, 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 support via a ball bearing at the end of the crankshaft flywheel side, suppressing twisting and deflection and enhancing crankshaft durability.
