Intake Manifold Pipe for Honda Helix CN250 & Elite CH250 | OEM 16210-KS4-840

Product Overview

Keep your classic Honda touring scooter on the road with this high-durability Carburetor Intake Manifold Pipe. Specifically designed for the legendary CN250 Helix and CH250 Elite, this part is a direct replacement for OEM #16210-KS4-840 and #16210-KM1-010. These liquid-cooled 250cc engines generate significant heat; over time, the factory intake boot can harden and crack, causing vacuum leaks that lead to hard starting and stalling. Our manifold is engineered with high-strength, heat-resistant materials to restore your scooter’s smooth idling and reliable performance

Key Features

• High-Temperature Resilience: Crafted from premium materials designed to thrive in the high-heat environment of a liquid-cooled 250cc engine bay, effectively preventing the drying and cracking common in older scooters.
• Leak-Free Vacuum Seal: Precision-manufactured to ensure an airtight connection between the carburetor and cylinder head, eliminating the lean-run conditions that cause "popping" and engine hesitation.
• Strict Quality Control: Every unit undergoes rigorous testing to ensure it withstands high-pressure intake cycles, providing a reliable and long-lasting riding experience.
• Corrosion-Resistant Design: The specialized rubber compound is engineered to resist degradation from modern ethanol fuels and engine oils, significantly prolonging the product's service life.
• Restores Smooth Idling: By stabilizing the air-intake volume, this manifold helps restore the smooth, whisper-quiet idle that the Honda Helix is famous for.
