Hyper Tuning Set with Big Throttle Body for CT125 Hunter Cub

【SP武川 01-02-0051 Hyper Tuning Set with Big Throttle Body CT125 Hunter Cub Engine Parts Takegawa】
■Product Description
The Hyper Tuning Set (with Big Throttle Body) includes a High Compression Piston Kit, FI-CON TYPE-X (injection controller), and Big Throttle Body Kit.

■Detailed Description
●High Compression Piston Kit
By replacing the piston while keeping the displacement unchanged and using the stock cylinder head and cylinder, output can be increased.
This piston has been meticulously designed with attention to detail to achieve higher compression, more efficient combustion, and reduced friction, pursuing the optimal piston shape. High-rigidity forged aluminum is used to withstand higher compression ratios.
Bore diameter 50mm (same bore diameter as stock)
Compression Ratio: High Compression Piston 12.5:1 (Stock Piston 10.0:1)
*When installing the high compression piston, the stock camshaft cannot be used. Also, when installing the high compression piston, simultaneous installation of SP Takegawa Sports Camshaft and FI-CON TYPE-X is required.
*Requires high-octane gasoline.
●Sports Camshaft (N-10)
Optimal profile designed to maximize the performance of the stock cylinder head, improving output performance.
Installing it on a stock engine improves output in the high RPM range.
By removing the decompression parts from the stock camshaft and assembling them into the Sports Camshaft, it becomes an auto-decompression specification.
●Big Throttle Body Kit φ28 (for stock cylinder head)
This product is an original SP Takegawa Big Throttle Body Kit developed for SP Takegawa engine parts.
It can be installed compactly around the engine without altering the vehicle's silhouette.
Additionally, no modification to the cowl or wiring is required for installation.
●FI-CON TYPE-X (Injection Controller)
This is an injection controller that can be connected to the genuine ECU with a coupler.
It comes pre-set with various MAPs for different engine specifications, so basic operation is complete and ready to run simply by selecting the MAP that matches your big bore kit or throttle body specifications on your smartphone or PC.
It offers enough content for advanced users to enjoy, such as adjusting settings based on existing MAPs or creating new MAPs according to their preferences.
It can connect to a PC or smartphone while the engine is running, allowing for convenient settings, with a tachometer screen and throttle opening graph screen, as well as engine temperature monitoring. It also includes a rev limit function.
Can be installed simultaneously with Honda's genuine immobilizer alarm.
●Regarding the installation of the High Compression Piston Kit
Installing SP Takegawa's High Compression Piston Kit significantly increases engine output and torque, which puts more strain on the crankshaft, such as twisting and deflection.
SP Takegawa recommends simultaneous installation of 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 at the flywheel end of the crankshaft, suppressing twisting and deflection.
