Recently got some decent weather to take the bike out after cleaning the carb, adding a larger starter jet, fuel screw and radiator guards. When I started it, it was running like I was constantly twisting the throttle. I didn't even have to give any gas to take off. Is there something that would cause this. I checked where the throttle cables go and they look like they have some slack so that can't be it. Could it be the fuel screw or even my hot start plunger? Help is greatly appreciated.
