Some people say this is not normal, to start a 500cc 1cil this easy.

Comperssion measured = 9:1

Ignition timing a bit retarded.

What do you think about this guys?

He is using the valve decompressor so yes if you take it to just past TDC using the decompressor then there will be no compressed gases and no resistance to kicking until the next TDC 680 or so degrees later, by which time the kick energy will be in the flywheels as inertia and will easily take it over a fully compressed TDC. Try that with a B50 and you are asking for trouble, wrong gearing on the kickstart lever, 10:1 compression and much lighter flywheels than B33.
