Hyper Tuning Set CT125 Hunter Cub

【SP Takegawa 01-02-0045 Hyper Tuning Set CT125 Hunter Cub Engine Parts Takegawa】
■ Product Description
This hyper tuning set allows for increased output by replacing the piston and camshaft while keeping the same displacement, and simultaneously installing an FI-CON TYPE-e (injection controller).

■ Detailed Description
● High-Compression Piston Kit
The optimal balance of piston shape and compression ratio delivers high output performance unmatched by other manufacturers.
By replacing the piston, output can be increased without changing the displacement of the CT125 (JA55), using the stock cylinder head and stock cylinder.
This piston is meticulously designed to achieve higher compression ratio, more efficient combustion, and lower friction, pursuing the optimal piston shape.
High-rigidity forged aluminum material is adopted to withstand the higher compression ratio.
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.
● Sport Camshaft (N-15)
The Sport Camshaft (N-15) is a camshaft developed for entry-level models.
It improves output performance with an optimal profile that brings out the full potential of the stock cylinder head.
Also, since the Sport Camshaft (N-15) does not have an automatic decompression mounting structure, it will be a non-decompression specification when installed.
● FI-CON TYPE-e (Injection Controller)
Installing a sport camshaft or muffler parts can significantly deviate from the ideal air-fuel ratio, so it is necessary to correct the fuel injection time with an FI-CON.
The FI-CON TYPE-e comes with multiple pre-set data optimized by SP Takegawa for SP Takegawa engine parts, allowing for easy selection, modification, and correction of setting data using a PC or smartphone to match your engine specifications.
Injection time adjustment can increase by a maximum of 5000μs and decrease by a maximum 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 using a PC or smartphone, which is very convenient during setting.
It can be used with all SP Takegawa products (for CT125) from stock displacement to bore-up kits.
● Can be connected to the stock ECU with a coupler
Since the controller wiring uses couplers compatible with the stock ECU, no wiring modification is required, and it can be attached to the stock ECU with a coupler.
● Regarding the installation of the high-compression piston kit
Due to the significant increase in engine output and torque with the installation of the SP Takegawa high-compression piston kit, the crankshaft experiences increased stress such as twisting and deflection.
To reduce the load on the crankshaft, SP Takegawa recommends simultaneously installing a crankshaft support adapter.
The crankshaft support adapter enhances crankshaft durability by adding ball bearing support to the flywheel end of the crankshaft, suppressing twisting and deflection.
