rattle/knock

[Smoked U]

If you already have AAA for your car, you can add RV/motorcycle for a few more bucks. I think mine covers me for 100 miles of towing.

Yellow Magna,
My '94 at 11k has demonstrated the same thing for several thousand miles.  Bought it Jan 2007 with 4K. Engine was silent and the clutch was a bit grabby.  Changed oil and fluids and follow each year/2-year. 
Listening with a stethoscope the knocking/clattering is loudest at the right hand forward cylinder head.  As rpm is increased, say from 800, the clatter first becomes intermittent and disappears a bit above 1500 rpm.  A few years ago a Honda MC mechanic just shrugged his shoulders. 
I used Amsoil 10W-40 for a couple of years and was unimpressed - clutch was still not smooth and the clacking was unchecked.  The best oil seems to me to be GN-4 10W-50. Clutch is perfect. 
The clacking is reduced and the running is supper smooth after a short highway speed run.  Could this clacking issue be carbon build up? 
I'm very interested to having the clacking disappear.

There is a technical bulleten on the '94's... It basically says to drill small holes in cam caps to increase oil flow...
Never did it to my yellow bike at 90k, noise has not gotten any worse
