Q1: What makes the 20S-16 different from a TPS sensor?
A: The TPS detects throttle position, while the stepper motor controls idle airflow.
Q2: Can this motor improve motorcycle acceleration?
A: It mainly affects idle operation rather than direct acceleration performance.
Q3: Why does idle speed become unstable?
A: Possible causes include stepper motor wear, carbon buildup, or electrical issues.
Q4: Is installation complicated?
A: Installation difficulty depends on the motorcycle model and throttle assembly design.
Q5: Does this motor work continuously while riding?
A: It mainly operates during idle control and related engine management adjustments.
Q6: How should compatibility be checked?
A: Compare the original motor number, connector, and mounting specifications.
