Okay I can give you some pointers in no particular order:
1. Change your brake fluids for fresh fluid. Flush the old fluid out well. You will have less chance of water/moisture buildup in the brake system.
2. Change your engine oil and filter. Same deal with water/moisture buildup,
3. Your bike will be on stands. Drop your tyre pressure to around 20psi. This way you won't have long term static pressure stress on the rubber. Also keep the bike in an area away from light, preferably a dark room. So no sunlight is hitting the rubber. Any rubber for that matter.
4. Give your bike a really good wash and clean
5. Clean and fresh lube your chain.
6. For any anodised or bare metal areas
(nuts, bolts, screws), soak a clean disposiable cloth in kerosene or WD-40 and give them a liberal wiping (if you can get a hold of Mil Spec PX-28 preservation fluid the better). With my bikes anything that is bare metal gets coated. Don't forget your sprockets /chain wheels and brake discs including the lightening holes (just put a thin smear on the discs with the kerosene, basically enough to just coat them). Don't be concerned about your brake pads. Don't forget to completely wipe /coat your exhaust system as well.
7. Keep a full tank of fuel in it. Some people will say different and mention preserving the tank. I avoid that like the plague. If the bike is kept in a cool dry place wrapped up out of the light, you shouldn't get too much evaporation.
8. Disconnect your battery. If its a gel cell, fully charge it, lube the terminals with non-conductive grease or vaseline and store it. Don't worry about a trickel charger.
9. Vermin. If you cover your bike (you should). Put out rat, mice and cockroach baits around the bike and under the cover. Blank up your airbox inlets. If you run pods then they won't have a cosy home to sleep and make babies in. Its up to you but you can spray WD-40 down the cans then blank them as well.
That's about all for the moment. That should just about cover it. This is basically a 'no one touchs it while your away' scenario.
Cheers Warp
