Hyper S Stage Bore Up Kit 80cc Product # 01-05-0352

The "Hyper S Stage Big Bore Kit" delivers a completely different engine output and torquey driving performance than the stock engine

Hyper S-stage Big Bore Kit includes S-stage Big Bore Kit 80cc, FI Controller 2 (Injection Controller), 35T Driven Sprocket, and NGK-CR8HSA Spark Plug.
By installing optional parts such as air filter and exhaust at the same time, the power output can be increased further.

■S stage big bore kit 80cc details
Using the stock cylinder head, the displacement can be increased to 80cc by changing the cylinder and piston.
The cylinder is equipped with an oil outlet to allow the oil to be taken out to the oil cooler.In addition, since SP Takegawa's original stick temperature sensor can be installed on the cylinder body, you can measure the cylinder temperature by purchasing SP Takegawa's compact LCD thermometer kit with stick temperature sensor.
The M5 temperature sensor can also be mounted on the oil plug bolt used for the oil outlet of the cylinder. If you do not use the oil outlet, you can measure the temperature by purchasing the SP Takegawa compact LCD thermometer kit with M5 temperature sensor.

■Sports Camshaft
This camshaft is designed to maximize the performance of the stock cylinder head.

■FI Controller 2 (Injection Controller) Details
This is SP Takegawa's original injection controller that can be easily changed by switching the rotary switch on the main unit without the need for complicated PC connection.
Despite the compact body, it has a built-in 3D correction map that has been set to match the SP Takegawa S-Stage big bore kit.
In addition, the built-in correction map can be fine-tuned by using the rotary switch on the main unit.
The rev limit speed is also 11, 500rpm which is higher than the stock ECU.

A special harness for each model is included, so it can be installed with minimum wiring work.

■It is recommended to install the SP Takegawa air filter at the same time.
By removing and installing the filter from the stock air cleaner box, the intake efficiency will be greatly improved and the power output in the high RPM range will be increased.
Also, by installing SP Takegawa's exhaust at the same time, the power output can be increased further.
You can choose from two types of filters, standard and high flow.
The high flow filter has a double-layered sponge structure and can be cleaned.
