Is there a one proper way to do a coolant change. I've drained all my coolant (hopefully properly so the b**ch doesn't airlock itself) and now I have to add new coolant. I'm not sure which color the coolant was because it's been awhile since I drained it. It might've been like a dark green. Should I run some water through the system to flush it and how should it be done. And also I'm not 100% sure how to bleed the system. Do I just add the coolant and let the bike run without the radiator cap?
