From Transport Canada:
On certain motorcycles, the rocker arm shaft retaining bolt could loosen, causing an oil leak. If the bolt was to separate completely, the engine could stall or lose power. This could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the rocker arm shaft retaining bolt.
