Over the July 4 weekend I will be returning with a 1988 883 (no known major engine mods). The bike has been setting up for about 5-7 years. Previous owner quit riding after developing allergy to UV rays and he just stored the bike (I am currently riding/working on a shovel that I got from him that was put up at the same time). Bike was running fine when shutdown. In addition to changing fluids, battery, tires and pouring some marvel mystery oil down each spark plug hole, what would be some other suggestions to minimize issues on first start and to minimize "start-up" costs for this bike. I plan to pull the plugs, squirt some Marvel down each cylinder and let it set for a while (day or two), then I was going to put it in gear with rear wheel elevated and try to turn the wheel to see if the pistons are frozen or not.
