Best way to drain all coolant?

I just bought a pro circuit water pump and need to drain all of the coolant out so I don't get any air bubbles! What is the best way. Is there a drain plug for it all? I drained it once since I got the bike and cant remember:bonk: Its for a 2005. Thanks guys!

um not sure about on ur bike but on my 07 theres a little alen key plug on the water pump cover you simply remove it an the coolant comes right out

don't worry about air bubbles, just fill your radiator, cap it and run the motor for a minute or so. let it sit for a few minutes then check the level and top it off. There is no need to try and bleed it like a brake system.
