Coolant Change

I've look at the Manuel and it doesn't explain how to change the coolant; I've looked for a drain plug but the only thing I was able to find was a video where he takes the hose off the water pump to drain. Is there not a drain plug anywhere? How are you guys draining your coolant. Thank you.
 
Just remove the lower hose, and let all of the coolant drain, reattach the hose, fill the radiator with a bottle of coolant flush, or better yet, white vinegar, and fill the rest of the way with Distilled water.
Run the bike until the thermostat opens, then drain the coolant again.
Do this one to three times, until the water draining out is clear.
Crank the bike with the lower hose off and let it run for about 10 seconds, so the waterpump will continue to pump out old coolant.
This will not harm the engine.
I also drain the coolant hot(I have rubber guanlet gloves to prevent burns).
When you're done, fill the radiator, leave the cap off(myself and several of us here use Engine Ice), then fill the coolant resivor.
Run the bike and wait for the thermostat to open.
Top off the radiator and overflow, and put the caps back on.
Go for a short ride, then check the coolant level again.
It is normal if the resivor level drops some in a few days, after any left over air in the system works it's way out.
Any overheating issues will be the result of a Big air pocket, and leaning the bike side to side can help remove them.
There is a bleeder valve on the thermostat housing, but it is usually not nesacerry to use it, other than in extreme and rare cases of trapped air.

Thank you, I am also going with engine ice, I run that stuff in all my bikes.
 
I've found it tricky to get the distilled water / coolant mixture right. After flushing with distilled water, apparently there's still some left in there after draining it. My 50/50 mix tested perfect before putting it in the bike but after running it in the bike, the coolant tested weak. I had to drain a small amount and add pure coolant a number of times before I got it right. It was a hassle but if the bike's stored in an unheated garage in winter, you need the coolant perfect. That's also best for anti-corrosion according to coolant manufacturers although I know, race bikes run pure distilled water. I wouldn't go with a premixed coolant or it's going to be awfully hard to richen it up if needed.

To clarify
Remove the lower hose on the Waterpump, not the radiator.
I did not say which one in my post above
Sorry about that.

No, you're good, that's what I was going to remove. I've watched some gen 2 vids. There's not much Gen 3 vids about removing, I do wish they would install a drain plug.
