Hard to say without more info. Could you tell if it was in the barrel or gearbox? Did it sound like a knock? Did you happen to use a Wisco piston? the skirt is shorter than stock and sometimes knock at low RPM's. the fact that it started easy, but now seems hard to start and knocks makes me think something didn't seat properly. Can you remove the plug and have it kick over easily and quietly?

Is there something wrong with the kickstart now? Just wondering why you are bumpstarting it.

It is going to be difficult to diagnose a "loose" sound over the internets. I think you need to start taking things apart until you find the source.
