When riding the temps sit at 190-210 but the longer i ride it the quicker the temps jump up when im just sitting at a light, sometimes it'll jump to 244 in less then 30 seconds. But when I bring the RPMS up past 3k it drops so theres air in my coolant system. I've tried to burp it but I think i'm doing it wrong. Please note im not too mechanically inclined :[.I've googled around to try and learn how but it still seems vague. Should i be letting the coolant just flow out of the radiator when burping? And also i've noticed metal flakes in the coolant, whats up with that?

Thanks in advance.
