I've recorded it a couple of times, but the knock is not distinctly heard in the video, so not much help.

Recently (now just under 40k miles on the bike), upon start-up in the morning, I hear 2 distinct knocks.
They're about 5 or seconds apart from each other.

I can't locate it ... I want to say "engine", or "final drive", or "clutch" ... I can't nail down the location.

The best I can liken the sound to ... take a 12" claw hammer and do a quick gentle "whack" on the garage concrete - sounds just like that.

Any ideas ???

Thanks for stopping in ... I'm fairly confident this knock is not related to a misfire. Something is knocking on something else.
And there's two knocks, though the span of time varies - sometimes one second, sometimes 5 seconds.

And one other thing ... (I always start in neutral) It doesn't matter if I have the the clutch lever pulled back or not.
