8:21 dude hahahahah that tap water will corrode your system... That´s why your water was orange when you unplugued the drain plug... And your flush method is wrong, you have to refill the system with water, close the system, start the engine, stop engine and unplug/drain... Repeat this 3 times at least. And once you finish, you start the bike like you did in 11:06 but with the radiator tap unplugued to let the air go outside... And after that, stop engine, open radiator tap and check level. I would rate your coolant change with a 5/10 😂
