This is how I bleed mine:
1.) Fill the system including overflow bottle.
2.) Go inside have a beer.
3.) Back to the bike, top up everything and seal. Start the bike. Go inside have a beer.
4.) Back to the bike, is the radiator fan on? No, go inside have another beer.
5.) Repeat step 4 until the fan comes on. If the fan still does not come on, go buy some more beer.
6.) Repeat step 5 until the fan comes on.
7.) If the fan still does not come on, send someone else to buy more beer.
8.) If the fan still does not come on repeat step 7.
9.) Repeat until everything ends OK.
10) If everything is still not OK, it is not the end.
