When installing the wrist pin circlips, ensure the clip open gap faces directly down (the 6 o'clock position) or directly up (the 12 o'clock position)—never place the circlip opening over the removal notch, as rotational inertia at high RPM can compress the clip and cause engine failure.\u003c\/p\u003e\n\u003ch3\u003eRecommended Pairings:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/kawasaki-kx100-moto-house-mx-performance-kit-and-accessories\"\u003eKawasaki KX100 \/ KX112 Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/kawasaki-kx-2-stroke-performance-parts-moto-house-mx-is-your-ultimate-destination-for-high-performance-kits-and-aftermarket-accessories\"\u003eKawasaki 2-Stroke Performance Parts\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/premium-motorcycle-chemicals-brake-fluid-bike-wash-coolant-chain-lubes\"\u003eMotorcycle Chemicals \u0026amp; Maintenance Products\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
