Before you go through the hassle, try one more...This worked for me. Maybe a fluke, but worth one more try...
Everybody orders the the lifter set..which is part #..06140-MAT-315. This comes as a kit with the gasket and washers.
If you look in the DEALER fiche..it says that this set is for 98, 99, and 00 XX's.
I ordered part #...14520-MAT-E21 which says its for 01, 02, and 03 XX's. It comes with only the tensioner.I installed this one, rode it for 8000 miles with no rattling.
Worth a try...
