I viewed you tube under coolant change on a motorcycle. Pretty simple to do on my dl 08. Just followed the video there really. I used a very long/skinny funnel to re fill the bottle/radiator. Had to tap the side cover area and rock the bike a little to make sure I got the air out. Use a rubber mallet for this with a cloth over the side cover to not mark the surface. Mix your coolant before or use pre mixed. You warm up the bike a little, rock it, stop it. Did that 8 times and all bubbles left the system. It's been at two, and occasionally 3 bars in hard traffic.
