07 yz450 looking to upgrade to boysen water pump

Any recommendations to change when opening up water pump. Doing cover gaskets. What else is recommended to change at same time

May as well do the pump impeller bearing and seals while you have it all apart. Should be good to go

Do I need to split case to replace seals or can it be done from pump side. Sorry but I haven't done any work in on pump yet.

Nope luckily it's just the case side... The guy in this video is goofy but he shows how to do the job easily.

Perfect thanks for great heads up
