■17r级+d缸盖
在正常缸盖形状的基础上,采用大直径气门进气:26mm/排气:22.5mm。
(12v猴原厂气门直径为进气19mm,排气16mm)
这是原厂sp竹川缸盖,"最佳气门夹角 "和 "燃烧室形状 "口形配合大直径气门。
虽然原厂车头的进、排气口直径均为14mm,但17r级的进气口直径已增至24.5mm,排气口直径增至19mm。同时,它还采用了三维端口形状来容纳阀门。结合更大直径的端口,可以使更多的进气和排气顺畅地流动。
气门:(进气26mm/排气22.5mm气门阀杆轴直径4.5mm)
通过更细的阀杆轴和腰部加工,将大直径气门增加的重量降到最低。
气门弹簧:采用不等速弹簧(2级节距)的单气门弹簧,以抑制高转速下的涌动。
自动减压凸轮轴
自动减压功能:
即使在高压缩比的情况下,发动机也能以较小的踢力启动,即使在排量较大的发动机车辆上也是如此。
R-10e/r-15e/r-20e凸轮轴可供选择。
88cc/scat106cc/106cc套件包含凸轮轴:r-10e
■ φ57 scat气缸(全铝陶瓷铣刀)
scat系列无需拆卸曲轴箱。普通曲轴可以保持原样进行`大排量增加。
气缸采用陶瓷镀层,具有卓越的耐久性、气密性和散热性。
此外,它的喷油口穿过气缸套,可以在发动机启动时将机油喷洒在气缸内壁、活塞裙部和活塞上,实现高效润滑和冷却。
■17R Stage +D Cylinder Head
Based on the stock head shape, large diameter valve intake: 26mm / exhaust: Adopt 22.5mm.
(12V Monkey stock valve diameter is intake: 19mm / exhaust: 16mm)
This is SP Takegawa's original cylinder head which adopts the most suitable valve pinching angle, combustion chamber shape and port shape for large diameter valves.
The port diameter of the stock head is 14mm for both intake and exhaust, while the port diameter of the 17R stage is 14mm for intake and exhaust: 24.5mm / exhaust: Larger diameter of 19mm.In addition, the adoption of a 3-dimensional port shape, combined with the larger diameter of the valve and port, makes it possible for more intake and exhaust gases to flow smoothly.
Valve: (Intake 26mm / Exhaust 22.5mm Valve stem shaft diameter 4.5mm)
The weight increase due to the larger diameter of the valve is kept to a minimum by the narrower stem shaft and waist machining.
Valve Springs: The single valve spring with unequal pitch (2-stage pitch) is adopted for optimum spring rate and suppresses surging at high rpm.
■Auto decompression camshaft
Auto decompression function: The engine can be started with a light kick force even on high compression and high displacement engines.
There are 3 types of camshafts, R-10E / R-15E / R-20E, and you can change the camshafts according to your application and enjoy the riding performance.
88cc / SCUT106cc / 106cc Kit Included Camshaft: R-10E
■ Φ57 SCUT cylinder (all aluminum ceramic plated cylinder)
With the SCUT series, there is no need to disassemble the crankcase, and the displacement can be increased significantly without changing the stock crankshaft.
The cylinder is plated with ceramic, which provides excellent durability, airtightness and heat dissipation.
Furthermore, an oil jet that exits into the cylinder sleeve enables uninterrupted oil jetting of the cylinder inner wall, piston skirt and piston inner wall during engine start-up for efficient lubrication and cooling.
The M5 temperature sensor can be connected to the side of the cylinder, and the cylinder temperature can be measured by using SP Takegawa's compact LCD meter (with M5 temperature sensor) or by changing the sensor part of the thermometer to the M5 temperature sensor.
