If my CB1100 has been sitting more than a week without starting I crank the engine with the throttle wide open for a few seconds. My understanding is that this prevents the fuel pump from pumping in order to unload the cylinders in case the engine is flooded. The engine won't start with the throttle wide open.
My theory is that by cranking the engine without starting it the oil pump pumps some oil to lubricate the pistons and valves. Releasing the throttle and cranking the engine starts it right up. My hope is that by doing this I am reducing wear on startup by insuring the engine parts have a nice coat of oil when starting after having been sitting for a long time. Maybe this is a pipe dream. Hopefully it causes no harm.
