Cast piston adopted.\n\u003cbr\u003eBore diameter 56mm. Compression ratio 11.2:1. Stroke 57.9mm (stock).\n\u003cbr\u003e●Sports Camshaft (N-15) Decompression Specification\n\u003cbr\u003eThe Sports Camshaft (N-15) is a camshaft developed for entry models. It improves output performance with an optimal profile that brings out the performance of the stock cylinder head.\n\u003cbr\u003eThe Sports Camshaft (N-15) will be a decompression specification when installed.\n\u003cbr\u003eGenuine decompression parts cannot be assembled to the N-15.\n\u003cbr\u003e●FI-CON TYPE-e (Injection Controller)\n\u003cbr\u003eWhen installing a sports camshaft or muffler parts, the ideal air-fuel ratio will deviate significantly, so it is necessary to correct the fuel injection time with FI-CON.\n\u003cbr\u003eInstallation is possible simply by disconnecting and connecting the coupler of the genuine ECU.\n\u003cbr\u003eFI-CON TYPE-e has multiple data sets prepared by SP Takegawa 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 stock displacement to bore up vehicles.\n\u003cbr\u003eIt 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.\u003c\/p\u003e\n\n\u003cp\u003e■Compatible Models\n\u003cbr\u003eHONDA\n\u003cbr\u003eGROM (JC75-1000001～)\u003c\/p\u003e\n\n\u003cp\u003e■Notes\n\u003cbr\u003e*Image is for illustration purposes only. Includes products with different sizes and colors.\n\u003cbr\u003e*Product design and specifications are subject to change without notice. Please understand.\n\u003cbr\u003e*Due to the significant increase in engine output and torque with the installation of SP Takegawa's e-stage bore up kit, the crankshaft will experience increased stress such as twisting and deflection. SP Takegawa recommends installing a crankshaft support adapter simultaneously to reduce the load on the crankshaft.\n\u003cbr\u003eThe crankshaft support adapter adds ball bearing support to the end of the crankshaft flywheel side, suppressing twisting and deflection and improving the durability of the crankshaft.\n\u003cbr\u003e*This product is made to order, so cancellations after ordering are not possible.\n\u003cbr\u003e*Due to being made to order, this product takes time to deliver. Also, please note that the manufacturer may discontinue the product or change its specifications without prior notice.
