hello i have just bought a vl and it runs really ruff i have changed the fuel pump today and runs a lot better but sill is a little doggy when i give it a good rev what should i fix next the fuel regulator or the injectors????????????

Try checking for a vaccume leak then try changing the spark plugs rotor button dizzy cap and leads for starters, who knows when the last time they wet changed was.... Start small mate then try air flow meter, oxy sensor, throttle position sensor,
