Or you can do what I do....
Nothing...
Its always on a battery tender whenever its in the garage.
Maybe every month or three I pull the cover off, start it - let it get up to temp - run it for 10 min more so fan cycles on and off and then switch off - leave to cool. recover.
Mine is Garaged - so never gets really cold.
I have tried fuel stabaliser - it made no difference - I fitted it to 2 bikes and did not to the other 2 - bith started and run correctly.
As for dumping oil and fuel - why do that??
Modern Synthetics do not get as Acidy as previous - even if they do - standing is no different to normal use.
As for fuel - if you choose fuel stabilisers - which is OK - then why drain off - they burn out with the fuel.
Keeping weight off the tyres is a good idea... but not essential... Do new car that are stored in lots get their tyres raised of the ground and fuel and oil dumped - hell no.
Near me the big import yard - near the sea (SALTY AIR) has maybe 20,000 cars - I am sure some of them must sit there in the open for a year before being sold..
There is nothing wrong with what Tony is saying (except maybe oil down plug - where you would need to crank engine by hand to distribute the oil - or it does no good - and just sits on the piston and does not coat the bore) - but is it needed??
4 bikes for maybe 6 years - never an issue with doing next to nothing... just my POV
