I dont have a center stand... and have found it impossible to source one down here. However, i have used to ways to clear the back wheel from the ground:
Jack where the center stand goes. I used a scissor jack on one of the sides where the bolt goes. Make sure your front wheel is turned completely to the left locked position first. A level floor also helps.
Now I use a jack stand to rest the bike on the right side swingarm. I lift the bike (bend ypur knees, back straight) and place the jack stand, rising up a couple of levels, so that the back wheel is clear.
Finally, i use a spray bottle with kerosene to clean, light brush with used tooth brush, spray again, dry with a rag, wait, dry again. Finally lube. I have used muc-off dry lube with very good results. I tried a couple of others but either got a completely caked chain or flung off too quickly. Have not tried motor or transmission oil (80w-90
I ride every day to work. Have got into the habit of lubing every 500km and full clean every 1500km approx. This has worked well for me. I will try to replace the kerosene, its pretty messy (but cleans a beauty).
My main concern is not to clean too much. Dont go wild with the brush! I'm thinking that its not a good idea to go rough on the o,x or z rings, and damage them or squeeze the grease that is trapped behind them.
It seems that if you do ANY sort of maintenance on the chain (light clean and lube, only lube, etc) it will make a big difference. Complete neglect will run your chain dry and quite likely give you some kinked links and/or split rings.
Having said that, i have found some blokes that hardly maintain the chain and still get 40k out of them... guess it depends how much work you want to put into it.
