Check your compression...  Could be a valve/valve guide/valve seat....

 :cherry:
Sometimes,  when you shut it off and the cam is riding on the lifter at a certain point,  the lifter will drain (collapse).   My old RK did that once after a return (trailered) trip from Daytona Bike Week.

Ran just fine going into the trailer,  but sounded like something was broken once I cranked it up after the trip.

Try just riding (easy-going) for a few miles around your neighborhood  or some back road.   If it was just a collapsed lifter,  it will gradually pump itself back up and the noise will go away and all is well.

Of course,  if that's not the problem,   you may really have a problem
