When i am stopped at light or at a stop sign and i put the bike in idle by pulling the clutch. When the light turns green and i give it gas while realeseing the clutch the engine just dies i must start moving before i realese the clutch and keep riding. how do i fix that or is that the way it is supposed to be. I have the Grubee skyhawk gt5 2011 motor with the cns carburator. I just built it and i am still breaking it in as stated in the instructions.
