Yamaha - Throttle Body 1 Air Intake Component 6CB-13751-10-00. Overview. When throttle response starts feeling off, this is one of the first places I look. The throttle body controls how much air your engine gets, and that directly affects how it runs and responds. If it's worn, dirty, or not sealing right, you'll notice hesitation or uneven power pretty quickly. Getting a clean, properly functioning throttle body back in place makes the motor feel sharp and responsive again..
