Bleeding cooling system on k75

[he3r0]

After a winter in the garage, I've pulled my rick to the open, and changed the oil :) as well as coolant.
but I've noticed that my clutch is slipping  :falldown:, so I've ordered new parts. However today, while i was riding to work, 
temperature light started to blink, and after a short second got solid. I've sped up to get air to cool the engine more, and it went down for a bit, but in the traffic jam, it came back.
I have not heard the fan engaging, and that will be the first thing I'll check upon my arrival at home, however, I was wondering if there is any procedure to bleed air from cooling system on the K75?
I have not seen any procedures in the manual, nor any "bleed screw" on the pump...
Thank you for the answers.

Squeeze the radiator hose on the lower right side of the engine (the one that goes through the crank cover) while the engine is idling. Do this repeatedly until you feel that the air has been expelled.

Thank you, I'll do that!

Did any coolant come out of the overflow tank under the seat on the right side?  Before you start the engine again, check the coolant level un the overflow tank and in the filler.  Top up the level in the filler and bring the level about half way between the high and low marks on the overflow tank.

Start the engine and let it warm up while you carefully squeeze any bubbles out of the hose that RBM mentioned.  Keep the level in the filler at the top while you do this. 

Have you ever flushed the cooling system or cleaned out the dirt in the radiator cooling fins?  This will make a big difference in running temperature if it hasn't been done in 25 years.

Yes there were drips around overflow tank, and level was above max, once everything cooled down, level (in overflow tank) got to perfect mid in between min and max. I have not cleaned radiator fins, though i did flush the system when i had water pump off to rebuild. I'll spend some more time with this after I'll get back home from work. plus I do not think that fan is working, so i guess some more troubleshooting will be needed.
Thank you.

Sounds like you had a bubble in the system and it may have cleared itself.  Things might be ok for the ride home.  If the fan is bad, there is a good replacement that doesn't cost as much as the BMW fan and there are instructions here for doing a neat install.

I've gor home with a little cooldown stop (traffic :(( ). And upon arrival, i've verified that indeed my cooling fan had "ceased to be"... Since prop is not exacly connecred to the rest of the fan... (already ordered replacement qith 800cfm and only few more watts), next stop - how to remove fairing in K75S :)
Thank you gentelman for help.

Fairing removal is easy.   There are great instructions with pictures in the tech section.
