Sounds like the fairly common wristpin slack slap noise. I have built a few bikes and ridden them for 100's of miules with that noise....none ever blew up.

i heard many noises from these engines and bike frames.
ringing noise: comes from head,place rubber hose between head fins.
scraping noise: place 2 or 3 gaskets under clutch cover or fix cover if dented.
tinging noise: chain is wacking bike fender,adjust chain and notch out fender.

i now have little or no noise from bike or engine.
