Good To Know

Q: Will this kit work on a 2007 YZ450F? A: No, this kit is specifically for 2003-2006 models; later years use a different water pump design.

Q: Is the mechanical seal already lubricated? A: The seal is dry and should be coated with coolant or light oil during installation as per the service manual.
