This advice is mainly for storage in unheated or semi heated premises or outdoors but it worth employing some of the actions wherever the bike is kept. These are IDEAL recommendations but I realise it is not possible for them all to be followed by some riders but the more that can be implemented the better.
1) Totally drain the carbs where applicable and close off the fuel tap or disconnect the fuel line from the tank.
2) Add additional antifreeze. Reset density before starting the bike
3) Add additional oil. Reset level before starting the bike
4) Seal off the exhaust pipes at the canister ends
5) Seal off Carb/Injector body intakes
6) Spray WD40 on casings and exhaust header pipes.
7) Disconnect Battery or frequently use trickle charger

If you do not intend to do any of the above but choose to fire up the bike on a regular basis then it is essential that the bike is run up to Normal Running Temp- stopped for 15 mins and then brought back to NRT before shutting down altogether.
START UP and WARM UP PROCEDURE AFTER STORAGE.
1) Check all fluid levels.
2) With the “RUN” button in the OFF position, so the engine cannot fire, turn the engine over for at least 20 seconds. You may need a spare battery or jump leads from another battery as you need sufficient charge left in the battery to proceed immediately to the next stage.
3) With the “RUN” button in the ON position and using the choke attempt to start the engine.
4) Allow to run on “tick-over” for a maximum of 10 seconds then slowly and gently raise and lower the revs to a maximum of 3,000rpm do not “snap” the throttle. Continue like this until NRT is achieved and then switch off the engine.
5) Wait 10 minutes and re-fire the engine. Immediately continue raising and lowering the revs as above to a maximum of 6,000rpm until it reaches NRT. Switch off engine
6) Re-check fluid levels. The bike is ready to ride
