*■Precautions
Exclusively for motorcycles equipped with SP Takegawa custom parts.
Do not use in conjunction with engine parts made by other companies.Failure to do so may result in engine malfunction or failure.
Rev limit speed is about 11,000rpm on all maps.
Rev limit RPM cannot be changed.
Please do not install aftermarket H.I.D kit or other company's LED headlight or fog lamp at the same time.
Some ballasts/inverters (voltage converters) emit high-voltage noise that adversely affects digital circuits, causing product failure or malfunction.
Do not use with other aftermarket ignition devices (ignition coils and plug cords) because they may cause malfunction or product failure due to increased radiated noise caused by rise in ignition voltage.
Do not use with other aftermarket power generators because they may cause malfunctions due to insufficient power generation or differences in voltage waveforms.
Do not install the headlight ON/OFF switch at the same time.
*There may be changes in product specifications due to the manufacturer's reasons..
■S-Stage Big Bore Kit 80cc
This big bore kit can change the displacement from the stock 50cc to 80cc by changing the cylinder and piston.
When installed together with the Hyper ECU, it delivers a torquey output characteristic different from that of the stock ECU.
Bore diameter: 53.5mm, Stroke: 35.6mm (stock), Compression ratio: 11.5:1
The cylinder can be fitted with an SP Takegawa Stick Temperature Sensor.
The cylinder temperature can be measured by using the SP Takegawa Compact LED Thermometer with Stick Temperature Sensor Set, or by changing the sensor part of the thermometer to a stick temperature sensor.
An oil outlet is also provided for the oil cooler.
We recommend the SP Takegawa dedicated Compact Cool Kit (oil cooler kit).Please refer to SP Takegawa Web Catalog.If the oil cooler is not installed, use the supplied oil plug bolt.An M5 temperature sensor can be mounted on the oil plug bolt, and an SP Takegawa Compact LED Thermometer can be used to measure cylinder temperature.
■Sports Camshaft
The sports camshaft is designed with the optimum profile to maximize the performance of the stock cylinder head when equipped with the S-stage big bore kit.
■High-capacity fuel injector (G-3)
Applicable specifications: Bikes equipped with S-Stage Big Bore Kit
High capacity fuel injector for SP Takegawa's S-Stage Big Bore Kit.The stock fuel injectors cannot inject enough fuel for the increased intake air volume, so large-capacity injectors are required.
This product may malfunction if installed in motorcycles with engine specifications other than those specified.
■Hyper ECU
Unlike conventional sub-controllers that use a stock ECU, this system controls everything.Easy installation by simply replacing the stock ECU!
It has a rev limiter cut function.
Rev limit RPM is approx. 11,000 RPM for all maps
Since the installation of big bore kits and exhaust parts can cause a significant deviation from the ideal air-fuel ratio, a hyper ECU must be installed to compensate fuel injection timing.
The Hyper ECU has several built-in setting data sets for SP Takegawa's custom parts, so you can easily select, change, and modify the setting data according to your engine specifications with a simple switch.
There is no need for a PC, smartphone, Internet connection, etc, as the setting can simply be done by switch operation.
The map also includes 9 preset maps for a wide range of custom bikes, including stock engine models with SP Takegawa intake/exhaust parts and SP Takegawa custom engine models with SP Takegawa intake/exhaust parts.
Furthermore, a fuel adjustment function is built in that allows you to increase or decrease the overall fuel mixture in a range of -9% to +9%.(Adjustable in 1% increments)
■Air Filter Kit
Remove the stock air cleaner box and install it in the stock connecting tube.
The intake efficiency is greatly improved and the power output can be increased at high rpm.
