Введение
Nothing ruins a trail ride faster than a throttle that refuses to snap back. Most riders run into this at some point: dirt, rain, and normal wear cause the throttle cable or housing to stick. Over time, these components can become worn, sticky, or damaged — making the bike difficult or even unsafe to operate.
This guide shows you how to replace the entire throttle assembly on a Coleman CT200U‑AB minibike so you can get back to reliable, responsive riding in under an hour.
Key Terminology
- Throttle housing – 2‑piece plastic shell that holds the grip and cable end on the handlebar.
- Ferrule – The metal collar crimped to the throttle‑cable sheath.
- Carburetor linkage – The lever on the carb accepting the inner cable.
- Free play – Small rotational slack at the grip (1–2 mm) before the cable pulls.
Hot engines & moving parts can cause serious injury.
‑ Let the engine cool completely.
‑ Remove the spark‑plug boot before you start.
‑ Wear safety glasses and gloves at all times.
