Nope. Started bike up, everything normal, after a short time, tapping sound gradually starts, gets louder and louder, I shut it off and pulled cam cover. Check, re-check, triple check everything. Rotated engine with starter for a little while, by hand for a long while, didn't find anything. Checked torque on cap bolts and oil tube banjo bolts. Back together, started it up, tapped for a short time, sound faded, everything fine. Balanced carbs today with new guages, runs better than it ever did. 332 trouble-free miles so far.
