The Wee Strom I bought ( 2008 model with 35000 klm on the clock ) also does this.
So I was really wanting to know what it is .
Done the shims , all good , tensioner and chains fine.
While poking around with my audiscope I discovered something which I think
just maybe the source.
I think it maybe well be injector hammer. Quite normal if they are clean. They tend to thud if they are dirty.
It is really loud through my audiscope with a distinct noise very similar to a tappet noise.
Now combine that with the massive chamber you have where your head stock is and I think you may find it very audible through there.
Well that is my diagnosis anyway.

You can always listen for your self .
