Rattle and Hum

[Grumpy Goat]

Rumble or thrum
...
All is good. The bike seems a little less 'perky' but that could simply be down to the fact that I'm doing more miles on my CBR600RR and many of those are on track with all that brings.
...

I'm noticing a deep rumble. A sort of a slightly hollow rumble. I don't think it's cam chain or tensioner related. Too deep sounding for that? It's a steady state thing and doesn't seem to relate to a specific gear or rpm. It doesn't seem to be getting any worse.

Just wondering ... did you start noticing this since getting the CBR600RR? Huge difference in the two engines are you are riding the 4-cylinder more (which would also explain why the RS appear to be more sluggish ... compared to by Tiger I have the reverse impression, although the Tiger is no slouch).

Sounds like your RS is maintained even better than my 60k+ 2016 RS (also mine since new) and I have no perceived rumble or thrum issues. I expect it would be a challenge recording that such that we'd hear a problem.
