Unless you see evidence of gunk and junk in the cooling system, flushing is over rated. Especially 3 times. Holy ****.

The Fjr has a bypass in the cooling system so pulling the T-stat or waiting for it to open is not necessary.

Just drain the old stuff. Fill with water and run it for a few minutes, then drain it again. Fill it with whatever coolant you like, burp it and be done.
