I took rt's advice, and rode the RX3 another 1,000 miles, with the metal tapping noise.
Then did another oil change:
The magnetic drain plug looked promising...about the same as usual:
The filter still had quite a few sparkles, but they were not as large:
Except for the metal tapping noise, the bike starts quickly, and has the same amount of power and acceleration as always.
Using a mechanic's stethoscope, the tapping is coming from the top end..... you know.....just like last time...at the 3,000 mile mark.
The tapping is not proportional to the engine rpm....just like last time.
That time the tapping turned out to be related to the decompression lever/mechanism, which required a new camshaft and related parts.
I never fully understood exactly what was making the tapping noise, and CSC did not return the damaged parts as requested.
Which leads to another disappointment...my last two emails to CSC Gerry have gone unanswered.
I'll try again when I'm ready to disassemble the engine.
