So,I got a bike on trade got it running. Question is I can't keep it running unless I run full choke. I just had the carb rebuilt. They told me that a lobe on the cam was bad or the rings are bad. But I can't wrap my head around that to the fact that itll run change gears and do everything it's supposed to. No smoke, nothing modified, new electrical (stator, cdi,ecu). I've ruled out air lock. Any other recommendations? I will be pulling carb tomorrow to check needle and float and jets. I'm just at a loss.
