The sound can be difficult to properly diagnose as it may resemble a metallic clicking in the front headlight area. The sound is coming from the rebound check valve within the front suspension and occurs when switching between compression and rebound. To address this, Indian Motorcycle has released this Service Advisory with instructions to install a new fork service kit that has an updated rebound check valve to correct the noise. This Service Advisory replaces ISA-21-01.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10251437-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10251437-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10251437","components":[{"id":"suspension","name":"Suspension","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"INDIAN","model":"CHIEF","year_from":2022,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"CHIEF BOBBER","year_from":2022,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"CHIEF BOBBER DARK HORSE","year_from":2022,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"CHIEF DARK HORSE","year_from":2022,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"SUPER CHIEF","year_from":2022,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"SUPER CHIEF LIMITED","year_from":2022,"year_to":2023,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
