I have a 2009 1300c with 1800 miles. Notice at slow speeds like when making a turn there is a lag with the throttle at low RPM´s. Sometimes feels like engine is not getting enough fuel so I pull the clutch to rev the engine until I´m out of the turn and can accelerate. I don´t notice performance issues at any other point. Idle is good, highway speed is good, etc. Can it be a fuel pressure issue, carb related?
