By using SP Takegawa's Compact LED Thermometer with M5 Temperature Sensor Set, the cylinder temperature can be measured.\n\u003cbr\u003eBore diameter 63mm. Stroke 57.9mm (stock).\n\u003cbr\u003eThe piston is standard for high-octane gasoline specifications.\n\u003cbr\u003eCompression ratio with standard piston: 11.0:1.\n\u003cbr\u003e●Sports Camshaft (N-20)\n\u003cbr\u003eOptimal profiles that maximize the performance of the stock cylinder head improve output performance.\n\u003cbr\u003eWhen installed on a stock engine, output in the high RPM range is improved.\n\u003cbr\u003eRegarding the Sports Camshaft (N-20), by removing the decomp parts from the stock camshaft and installing them on the sports camshaft, it becomes an auto decompression specification.\n\u003cbr\u003e●FI-CON TYPE-e (Injection Controller)\n\u003cbr\u003eWhen installing a sports camshaft or muffler parts, the air-fuel ratio can deviate significantly from ideal, so the FI-CON is necessary to correct the fuel injection time.\n\u003cbr\u003eInstallation is possible simply by disconnecting and connecting the stock ECU coupler.\n\u003cbr\u003eThe FI-CON TYPE-e comes with multiple pre-set data tailored 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.\n\u003cbr\u003eInjection time adjustment ranges from a maximum increase of 5000μs to a maximum decrease of 7500μs, making it widely applicable from stock displacement to bore-up vehicles.\n\u003cbr\u003eIt is also very convenient for setting, as it features monitoring functions for engine RPM, engine temperature, throttle opening, and injector opening\/closing rate using a computer or smartphone.\n\u003cbr\u003e●Big Throttle Body Kit φ28\n\u003cbr\u003eThis product is an SP Takegawa original big throttle body compatible with stock air cleaner boxes\/connecting tubes.\n\u003cbr\u003eWhile the stock throttle body is φ24mm, the SP Takegawa big throttle body is φ28mm.\n\u003cbr\u003eNo modification to the cowl or wiring is required; simply replace the stock throttle body with this big throttle body to maximize the performance of the stock cylinder head and increase output.\u003c\/p\u003e\n\n\u003cp\u003e■Compatible Models\n\u003cbr\u003eHONDA\n\u003cbr\u003eSuper Cub C125 (JA48-1000001～)\u003c\/p\u003e\n\n\u003cp\u003e■Notes\n\u003cbr\u003e※Image is for illustration purposes only. It includes products with different sizes and colors.\n\u003cbr\u003e※Product design and specifications are subject to change without notice. Please be aware.\n\u003cbr\u003e※The installation of SP Takegawa's S-Stage bore up kit significantly increases engine output and torque, which places increased stress on the crankshaft, such as twisting and deflection. SP Takegawa recommends simultaneously installing a crankshaft support adapter to reduce the load on the crankshaft.\n\u003cbr\u003eThe crankshaft support adapter adds support to the flywheel side end of the crankshaft with a ball bearing, thereby suppressing twisting and deflection and enhancing crankshaft durability.\n\u003cbr\u003e※This product is made to order, so cancellations after ordering are not possible.\n\u003cbr\u003e※As this product is made to order, it may take some time for delivery.
