Service bulletin KTB2402

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

During continuous product development, the exhaust flap control on the above-mentioned Super Duke models was improved. Performing the update prevents a possible malfunction of the exhaust flap and error messages. On affected 2020, 2021 and 2022 Super Duke models the following updates must be performed: •Install a new V-clamp D=70.1 (#61705058200) on the exhaust (see Fig.1). An additional anti-twist device on the improved clamp prevents possible damage to the radiator. •Install a new header gasket 54 mm (#61705005105) on the exhaust (see Fig.1). •Install the new repair kit (#A62405031044) for the exhaust flap control (see Fig. 2). •Install the latest software file. •Use action code 00 for this update. On affected 2023 Super Duke models the following update must be performed: •Install the latest software file. Note: Model year 2023 Super Duke’s already have the new V-clamp D=70.1, header gasket 54 mm and repair kit installed therefore these parts do not need to be replaced and updated on the 2023 Super Duke models. Only the latest software file needs to be installed on 2023 Super Duke models. •Use action code 01 for this update.
