What year cdi box will fit on a 1989 Yamaha warrior?

A 1989 Yamaha Warrior typically uses a CDI box from the same model year or compatible models from the late '80s to early '90s. You can look for CDI boxes specifically designed for the 1987-1990 Yamaha Warrior 350, as they are likely to be interchangeable. Always confirm compatibility with part numbers or consult a detailed parts guide before purchasing.
