Hyper S-Stage Bore Up Kit 145cc Grom

[SP Takegawa 01-05-5464 Hyper S-Stage Bore Up Kit 145cc GROM Engine Parts Takegawa]
■Product Description
The Hyper S-Stage Bore Up Kit includes the S-Stage Bore Up Kit, FI-CON TYPE-e (injection controller), Big Throttle Body Kit, and large capacity injector.

■Detailed Description
●S-Stage Bore Up Kit 145cc
This bore up kit allows you to change the displacement from the stock 124cc to 145cc by replacing the cylinder and piston.
When installed simultaneously with the FI-CON TYPE-e (injection controller), it achieves powerful output characteristics different from the stock engine.
The cylinder uses an aluminum iron-sleeved cylinder.
Bore diameter 54mm. Stroke 63.1mm (stock). Compression ratio 11.2:1.
Since the cylinder can be fitted with an SP Takegawa M5 temperature sensor, you can measure the cylinder temperature by purchasing a separate thermometer (Compact LED Thermometer with M5 temperature sensor).
*Since the displacement will be 125cc or more, it cannot be ridden on public roads under light motorcycle class 2 registration. This is for competition use only.
●Sports Camshaft (N-10)
The optimal profile maximizes the performance of the stock cylinder head, improving output performance. When installed on a stock engine, high-revolution range output is improved.
By removing the decomp parts from the stock camshaft and installing them on the sports camshaft, it becomes an auto decompression specification.
●Big Throttle Body Kit φ34 (for stock cylinder head)
This product is an original SP Takegawa big throttle body kit developed for SP Takegawa engine parts.
It can be compactly stored around the engine and installed without disturbing the silhouette of the vehicle.
Also, no processing of the cowl or wiring is required for installation. An air filter with excellent intake efficiency is included.
*Cannot be used with stock engines.
By adopting a φ34mm big throttle body, it maximizes the performance of SP Takegawa engine parts and enables increased output.
*The genuine air cleaner box cannot be used.
*When installing this product, the genuine air cleaner box must not be removed but left in place, as the shroud fixing part will be needed.
●FI-CON TYPE-e (Injection Controller)
When installing a sports camshaft or muffler parts, the ideal air-fuel ratio will be significantly deviated, so it is necessary to correct the fuel injection time with FI-CON.
Installation is possible simply by disconnecting the coupler of the genuine ECU and connecting it.
FI-CON TYPE-e has multiple pre-set data settings by SP Takegawa for SP Takegawa engine parts, so you can easily select, change, and modify setting data using a computer or smartphone according to your engine specifications.
The injection time adjustment can be increased by a maximum of 5000μs and decreased by a maximum of 7500μs, making it widely applicable from stock displacement to bore-up vehicles.
It is equipped with monitoring functions for engine speed, engine temperature, throttle opening, and injector opening/closing rate using a computer or smartphone, which is very convenient for setting adjustments.

■Compatible Models

■Precautions
*Images are for illustration purposes only. Includes products with different sizes and colors.
*Product design and specifications are subject to change without notice. Please understand.
*Due to the significant increase in engine output and torque with the installation of SP Takegawa 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 a ball bearing, thereby suppressing twisting and deflection and enhancing crankshaft durability.
*This product is made-to-order, so cancellations after ordering are not possible.
*Please note that this is a made-to-order product and delivery may take some time. Also, please be aware that the manufacturer may discontinue the product or change specifications without prior notice.
