What part of the world are you in ?
You should put that into your profile to get the best help
Different places can get slightly different fuel systems on their bikes.
Also remember every time your fuel pump primes it will produce pressure, if you have a leaking injector that pressure will flood fuel into the cylinder.
A good indicator of a leaking injector is the bike will require the throttle opened to start after a short stop as there will be excess fuel and a lack of oxygen in the cylinder.
