Hyper S-Stage N-20 Kit 181cc Big Throttle Body Monkey 125

SP TAKEGAWA 01-05-0567 Hyper S-Stage N-20 Kit 181cc Big Throttle Body Monkey 125 Bore Up Engine Parts Takegawa】
■Product Description
The Hyper S-Stage N-20 bore up kit includes the S-Stage N-20 bore up kit, FI-Con TYPE-e (injection controller), big throttle body kit (with air filter kit), sensor stay kit, and spark plug.

■Detailed Description
●S-Stage Bore Up Kit 181cc
This bore up kit changes the displacement from the stock 124cc to 181cc by replacing the cylinder and piston.
When installed together with the FI-Con TYPE-e (injection controller), it achieves torque-rich output characteristics different from the stock engine.
The cylinder uses an all-aluminum ceramic plated cylinder with excellent durability, airtightness, and heat dissipation.
Bore diameter 63mm. Stroke 57.9mm (stock).
The piston is standard for high-octane gasoline.
Compression ratio standard piston 11.0:1.
●Sports Camshaft (N-20)
The optimal profile maximizes the performance of the stock cylinder head, improving output performance.
When installed in a stock engine, it improves output in the high RPM range.
For the sports camshaft (N-20), remove the decompression parts from the stock camshaft and assemble them to the sports camshaft to make it an auto-decompression type.
●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 by simply unplugging the stock ECU coupler and connecting the FI-Con.
The FI-Con TYPE-e comes with multiple data settings developed by SP Takegawa to match SP Takegawa engine parts, allowing for easy selection, modification, and adjustment of setting data using a PC or smartphone to match the engine specifications.
The injection time can be adjusted with a maximum increase of 5000μs and a maximum decrease of 7500μs, making it widely applicable from stock displacement to bore-up vehicles.
It features a monitoring function for engine RPM, engine temperature, throttle opening, and injector opening/closing rate using a PC or smartphone, which is very convenient for setting adjustments.
●Big Throttle Body Kit (with Air Filter Kit)
The kit consists of a big throttle body kit for the stock cylinder head, a big throttle body air filter kit, and a sensor stay kit.
It maximizes the performance of the stock cylinder head and achieves high output.
You can enjoy engine characteristics that rev smoothly up to high RPMs.
Big throttle body bore diameter: φ34
Air filter kit (for big throttle body): Increased surface area provides high intake efficiency. Includes blow-by union.
The big throttle body kit includes a fuel injector ASSY. (00-00-0487).

■Notes
*The image is for illustration purposes only. It includes products of different sizes and colors.
*Product design and specifications may change without prior notice. Please understand.
*Due to the significant increase in engine output and torque with the installation of SP Takegawa S-Stage bore-up kits, the crankshaft is subjected to increased stress 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 supports the flywheel side end of the crankshaft with an additional ball bearing, suppressing twisting and deflection and improving crankshaft durability.
*This product is made to order, so cancellations after ordering are not possible.
*As this is a made-to-order product, it will take some time for delivery. Also, please note that the manufacturer may discontinue the product or change its specifications without prior notice.
