Milk or beer crate, wiggled under the engine by oiking the bike over on its side stand and kicking the crate under the engine. Assistance with a pile of bricks or a car jack if needed depending on the balance point and which wheel/s you're taking off. Not recommended and not safe for you or the bike. But that was how I did it before I could afford paddock stands....and that was on big fours

Edit: When I say 'before I could afford paddock stands' I actually mean 'before I met someone who already owned paddock stands I could use'
