Standards: For Cub 90 CD90 engine (HA cylinder/R15E)
*113cc big bore cylinders require crankcase modification to be installed. With the installation of the 17R Stage+D, the carburetor and exhaust will need to be changed in order to get the full performance of the engine. However, SP Takegawa does not sell carburetor kits or custom exhausts for CD90, Super Cub 90, Cub 100EX. Therefore, this product is designed for CD90, Super Cub 90 and Cub 100EX engines (stand-alone). For Monkey and Gorilla equipped with the applicable engine.Please purchase with understanding. *There may be changes in product specifications due to the manufacturer's reasons.
*Depending on the lot, the product may be delivered with the old price and label with the old JAN code before the price change.
The new camshafts are designed with a new profile to increase the power output in the higher RPM range This is the "17R Stage +D Big Bore Kit" for Par Cub 90 and Cub 100EX engines. The auto decompression camshaft allows the engine to be started with a light kick even with high compression engines.
■17R Stage E 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. 124cc kit included camshaft: R-15E
■For 113ccΦ54HA cylinder (all aluminum ceramic plated cylinder) It is the same design as the stock cylinder of the Cub engine in appearance (the height of the cylinder is different).Ceramic plating is applied to the 113cc HA cylinder for durability and airtightness It has excellent heat dissipation and heat resistance. 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.
■Piston The piston has a molybdenum coating on the skirt for better initial adhesion.
