Includes parts list.\n\u003cbr\u003eThe primary kick-starter system allows the engine to be started by disengaging the clutch, regardless of which gear it is in, making it ideal for racing use where quick engine starting is required for re-starts. Additionally, with a primary kick, the power is transmitted directly to the drive gear without going through the transmission, reducing the load on the transmission during engine startup.\u003c\/p\u003e\n\n\u003cp\u003e【Features of the Half Combo Kit】\n\u003cbr\u003e・New design SP Takegawa original reinforced crankcase\n\u003cbr\u003eThe SP Takegawa original reinforced crankcase is a high-quality crankcase specifically designed with increased case rigidity to handle the stress on the crankcase that occurs with larger displacements.\n\u003cbr\u003eThe oil pump employs a crankshaft direct-drive oil pump. It offers approximately twice the discharge volume compared to chain-driven reinforced oil pumps.\n\u003cbr\u003eThe breather pipe has an inner diameter of 6mm, compared to the normal 4mm, to reduce the internal pressure of the crankcase in large displacement engines.\n\u003cbr\u003eThe crankcase body is equipped with an oil jet mechanism that constantly sprays oil directly onto the small end of the connecting rod and the back of the piston for lubrication and cooling.\n\u003cbr\u003eDedicated bearing hold plates are installed for the mission bearings, which receive large torque.\u003c\/p\u003e\n\n\u003cp\u003e・Reinforced clutch\n\u003cbr\u003eThe reinforced clutch uses 5 discs to eliminate clutch slip in high-power engines.\n\u003cbr\u003eOnly available as a wet special clutch, with a magnesium die-cast cover.\n\u003cbr\u003eThe clutch cover used in the wet clutch is a patented clutch cover that allows for thermostat installation.\n\u003cbr\u003eBy installing the separately sold thermostat unit, overcooling can be prevented. Furthermore, an oil outlet is provided, allowing for oil extraction to an oil cooler.\u003c\/p\u003e\n\n\u003cp\u003e・Stroke-up crankshaft\n\u003cbr\u003eTo accommodate high-power engines, the stroke-up crankshaft uses special bearings with an enlarged inner diameter of the journal bearing.\n\u003cbr\u003eThe shaft diameter of the journal section, where stress concentrates on the crankshaft, is 22mm, improving strength and durability. Additionally, special surface treatment on the crankshaft further enhances durability.\u003c\/p\u003e\n\n\u003cp\u003e・TAF 5-speed cross mission (S Touring 5-speed)\n\u003cbr\u003eThe TAF 5-speed cross mission combines high durability with excellent operability.\n\u003cbr\u003eGear ratio: 1st: 2.357 2nd: 1.611 3rd: 1.190 4th: 0.958 5th: 0.807\u003c\/p\u003e\n\n\u003cp\u003e・SP Takegawa original aluminum die-cast generator cover\n\u003cbr\u003eA separate type drive sprocket cover is adopted, allowing sprocket replacement by removing only the sprocket cover part without removing the generator cover.\u003c\/p\u003e\n\n\u003cp\u003e・Kit Contents\n\u003cbr\u003eThe kit consists of parts specifically for the primary type.\n\u003cbr\u003eIt includes a reinforced crankcase, cross mission, wet special clutch, magnesium die-cast clutch cover, and crankshafts for various displacements, all pre-assembled. Also included are a 910mm clutch cable, a 1000mm breather hose, and 2 clips.\u003c\/p\u003e\n\n\u003cp\u003e■Applicable models\n\u003cbr\u003eThis kit is for those who currently have the applicable cylinder heads and displacement installed on their vehicle, or who have already purchased them.\n\u003cbr\u003eApplicable models:\n\u003cbr\u003eMonkey\/Gorilla\n\u003cbr\u003eMonkey BAJA\/Monkey R\/RT\n\u003cbr\u003eApplicable displacement: SCUT 138cc\n\u003cbr\u003eApplicable cylinder heads (with decompression):\n\u003cbr\u003eR Stage +D\n\u003cbr\u003eSuper Head +R\n\u003cbr\u003eTwin Spark Super Head +R\n\u003cbr\u003eSuper Head 4V +R\n\u003cbr\u003eDOHC 4V +D Head\u003c\/p\u003e\n\n\u003cp\u003e■Notes\n\u003cbr\u003e*Ignition parts such as the outer rotor are not included.
