Piston locked in barrel: Diesel fuel, good soaking. Time, several hours or even days. Fat bit of wood. Big old hammer. Good luck.

Wd40 won’t shift it, I use bulldog bdx, it unseised a Kawasaki z1000 that sat outside for 30 years, soak it, a couple of times, leave it 48 hours and gently turn it over, patience is your friend

Heat is your friend with shifting anything stuck, along with a good penetrating solution. Either opo it in the oven for a couple of heat cycles or a heat gun will get it hot with patience.  
As for manuals, The Guzzitek is usually good but has nothing for the 4 cylinder models. Maybe try looking for Benelli manuals as they are the same bike with different badges. Alternatively a Honda 500-4 manual may help as Guzzi just copied the engine!
