What the ministry says is wrong
原動機のカムシャフト固定方法の検討が不十分なため、カムシャフトを固定するプレートのボルトの締付力が不足しているものがある。そのため、そのままの状態で使用を続けると、ボルトが緩んでカムシャフトを固定できなくなり、最悪の場合、エンストし再始動できなくなる。What is to be done about it
全車両、当該プレートを対策品に交換するとともに取付けボルトを新品に交換し、新たに設定した締付けトルクで締付ける。The two passages above are quoted in Japanese because that is the language the ministry published them in. This site keeps the wording a register had when it was read, and does not translate a safety notice.

Reading this against the source
This page is what MLIT published in the recall notices it publishes, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /japan, and how the reading is done is set out in the method.
This register keeps an index of its own for every maker and every year it holds: Japanese recalls on a Yamaha: 186 in the register, and 380 Japanese vehicle recall notifications filed in 2025.
