Stroke 41.4mm (normal). Compression ratio 11.5:1.\n\u003cbr\u003eThe cylinder has an oil outlet for an oil cooler.\n\u003cbr\u003eWe recommend installing the SP Takegawa oil cooler kit at the same time. If an oil cooler is not installed, use the included oil plug bolt.\n\u003cbr\u003eSince this oil plug bolt 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).\n\u003cbr\u003e●Sport Camshaft (for vehicles equipped with SP Takegawa Bore Up Kit and FI-CON TYPE-e)\n\u003cbr\u003eThe sport camshaft adopts an optimal profile that maximizes the performance of the normal cylinder head when the S-Stage Bore Up Kit is installed.\n\u003cbr\u003e●Big Throttle Body Kit φ24\n\u003cbr\u003eThis kit improves output performance by simply replacing the genuine throttle body without the need for fairing or wiring modifications.\n\u003cbr\u003eIt improves output performance at high RPMs, which is not found in normal throttle bodies, allowing for an engine that revs without stress.\n\u003cbr\u003eThis product may cause malfunction if installed on a vehicle with engine specifications other than those specified.\n\u003cbr\u003e●Large Capacity Fuel Injector (G-4)\n\u003cbr\u003eThis is a large capacity fuel injector for vehicles equipped with SP Takegawa S-Stage Bore Up Kit, R-Stage Bore Up Kit, and Big Throttle Body.\n\u003cbr\u003eThe genuine fuel injector has insufficient fuel injection for the increased intake air volume, so a large capacity injector is required.\n\u003cbr\u003eThis product may cause malfunction if installed on a vehicle with engine specifications other than those specified.\n\u003cbr\u003e●Air Filter\n\u003cbr\u003eRemove the normal air cleaner box and install it on the throttle body.\n\u003cbr\u003eThe normal leg shield can be installed as is.\n\u003cbr\u003eIntake efficiency is greatly improved, allowing for increased output at high RPMs.\n\u003cbr\u003eThe filter has a blow-by union, so it can be connected to the blow-by hose using the included union.\n\u003cbr\u003e●Drive Sprocket 16T (Steel)\n\u003cbr\u003eAllows for a change in reduction ratio with increased output.\n\u003cbr\u003eLightweight design \/ heat treated for increased durability.\n\u003cbr\u003e●FI-CON TYPE-e (Injection Controller)\n\u003cbr\u003eCan be installed on the genuine ECU with a coupler-on. The specified RPM is 10500rpm or less.\n\u003cbr\u003eInstalling a bore up kit or muffler parts will cause the air-fuel ratio to deviate significantly from the ideal, so it is necessary to correct the fuel injection time with FI-CON.\n\u003cbr\u003eFI-CON TYPE-e has multiple setting data built-in to match 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\u003eThe injection time adjustment can be increased by a maximum of 5000μs and decreased by a maximum of 7500μs, making it suitable for a wide range of vehicles from normal displacement to bore up vehicles.\n\u003cbr\u003eIt is equipped with monitoring functions for engine RPM, engine temperature, throttle opening, and injector opening\/closing rate using a computer or smartphone, making it very convenient for setting (Please refer to the separate FI-CON TYPE-e for details on the functions).\n\u003cbr\u003eIt can be used for SP Takegawa products from normal displacement to S-Stage\/R-Stage bore up kits. \u003c\/p\u003e\n\n\u003cp\u003e■Compatible Models\n\u003cbr\u003eHONDA\n\u003cbr\u003eSuper Cub 50 (FI) (AA01-1700001～)\n\u003cbr\u003eLittle Cub (FI) (AA01-4000001～) \u003c\/p\u003e\n\n\u003cp\u003e■Precautions\n\u003cbr\u003e※Images are for illustration purposes only.
