Hyper Tuning Set with Big Throttle Body GROM MSX125

【SP武川 01-02-0034 Hyper Tuning Set with Big Throttle Body GROM MSX125 Engine Parts Takegawa】
■Product Description
A hyper tuning set that enables increased output by replacing the piston and camshaft without changing the displacement, and simultaneously installing an FI-Con TYPE-e (injection controller).

■Detailed Description
●High Compression Piston Kit
With an optimal piston shape and compression ratio balance, this kit delivers high output performance unmatched by other manufacturers.
Without changing the displacement of the Monkey 125 (JB02), and using the stock cylinder head and cylinder, replacing the piston allows for increased output.
This piston was meticulously designed to achieve higher compression, more efficient combustion, and lower friction, pursuing the optimal piston shape.
High-rigidity forged aluminum is used to withstand higher compression ratios.
Bore diameter 52.4mm (same bore diameter as stock)
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 output performance with an optimal profile that brings out the best in the stock cylinder head.
When installed, the Sports Camshaft (N-15) will be a decompression specification.
Genuine decompression parts cannot be assembled with 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 the FI-Con is necessary to correct the fuel injection time.
It can be installed simply by unplugging and connecting to the stock ECU coupler.
The FI-Con TYPE-e comes with multiple pre-set data configurations by SP Takegawa for SP Takegawa engine parts, allowing for easy selection, modification, and adjustment of settings data via a computer or smartphone according to the engine specifications.
The injection time can be adjusted by up to 5000μs for increase and 7500μs for decrease, making it suitable for a wide range of vehicles from stock displacement to bore-up engines.
It features monitoring functions for engine speed, engine temperature, throttle opening, and injector opening/closing rate via a computer or smartphone, which is extremely convenient for setting adjustments.
●Big Throttle Body Kit (with connecting tube)
Kit configuration: Big throttle body kit for stock cylinder head with connecting tube for big throttle body (connects to stock air cleaner box).
Maximizes the performance of the stock cylinder head and achieves high output.
Enjoy engine characteristics that rev smoothly to high RPMs.
Big throttle body bore diameter: φ34
The big throttle body kit includes the fuel injector ASSY. (00-00-0487).
●Regarding the installation of the High Compression Piston Kit
Installing 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 simultaneously installing a crankshaft support adapter to reduce the load on the crankshaft.
The crankshaft support adapter enhances crankshaft durability by adding ball bearing support to the flywheel end of the crankshaft, suppressing twisting and deflection.
