Tbh I wouldn't have said fuel injectors 'gush it out'..It should be a fine mist/fan pattern that puts in exactly whats needed.

Maybe putting something like REDEX in the tank will help clean the injector up. I know modern fuels have cleaning agents in them but in my experience using REDEX has cured starting issues on a variety of bike's.Especially when they have been stood a while.

When i start mine its a simple push of the button with no throttle needed.
