So I decide to flush my cooling system today. Half hour to strip off the plastics. I read the manual and start to take out the drain bolt at the water pump. With a big bucket ready, I take out the bolt. Green fluid is slowly dribbling out. I decide to take off the radiator cap which is on the other side of the bike. When I do, the fluid shots out the hole three feet, completely missing the bucket. But the fluid stream doesn't miss my Haynes manual which is just two feet away.
I put in some Zerex flush. Says it is safe for aluminum. The label says to drive the vehicle for three hours. Wife doesn't believe it until I show her the label. Yahoo. I come back to the garage, drain and flush the Zerex and add Prestone, which it says is safe for aluminum and contains no silica. I'll test it next week.
Here's a picture of my CBR without side plastic. Looks like a Hooligan bike.
