Throttle bodies or camchain tensioner?

Right. Update.
Dropped in at NOG this afternoon and asked Matt if one of the chaps could have a listen. Being good eggs, they did. "Sounds like the RH camshaft" was the verdict.
So, booked in for a week Monday for surgery. If I had a workshop (rather than working on the pavement) and a bit more time I'd have a go - but no time and no workshop.
Good to see everyone at NOG though - even got some quality abuse ("Red Aerostich and white hair? I thought it was Santa.") and a coffee from Possu.

Surely if the camshaft was worn you’d have more symptoms than just a bit of noise? Never heard of a camshaft wearing out before – how many miles on the pig? Whilst NOG are indeed excellent it’s always worth considering Andrew Sexton. If the camshaft is indeed worn, I’d look at getting some used RS cams on ebay – I would have thought that OEM would cost a small fortune.
Thanks Alf. I've used Andrew before and, atlhough his work is absolutely second-to-none and he's an utter craftsman (and a decent chap), I simply can't afford him. I would imagine - from experience - that NOG would be cheaper by some margin than Andrew!
Point taken – he’s not cheap and knows nothing about customer service but he does do a great job. Proper old school engineer who loves BMW’s. Lack of courtesy bike, living in the middle of nowhere and not opening til 9 isn’t great though
However when it comes to proper engine work as opposed to general servicing, I know who'd I'd rather use
Good luck either way

Indeed. I know just what you mean. Mr S is a very, very fine engineer. He had my old RS running better than when it was new.
Problem is, there aren't really too many BMW alternatives in Oxfordshire. Although the NOG guys are good lads of the first order they're still saddled with the BMW labour rates. I don't know of anyone else.
I'd certainly head it St Eptoe's way for a job like this, but I can't escape the office for long enough to take it.
Clicky clacky ticky tappy -
I forgot all about the pushrods until i had a tappy bike in at the weekend with that exact problem.
I've posted it many times as well, but seeing so many bikes you tend to forget until one pops up again.
Mark, it might be worth checking your pushrods before throwing loads of cash at it.
Nice and simple and on it's way again a happy quiet chappy
New style pushrod and old type of rod ( old style on top in picture)
This is what happens to them and causes a tappy engine. They usually only get loose when hot, they seem perfect when cold and you won't feel any play.

Thanks Neil - that could well be the source of the noise. It's certainly coming from the right place.

Took the Panzer to NOG who investigated the rattle. Reckoned it was the endfloat out, so adjusted it to spec. Odd, as I'd done the same thing a week earlier - but I'm very happy to put my hand up to cocking it up
Also ,kindly sorted out the stripped rocker cover bolt threads (thanks, PO 
) but, strangely, replaced one of the allen key bolts for a torx head!
Unfortunately, still as tappy as before. So, today went back to NOG and bought a few pushrods. Had a happy hour or so taking off bits of valve assembly, taking out the old 'uns and and fitting the new 'uns.
Absolutely not one jot of difference. Rattly-tappy racket still there.
Now just gone to ride as normal and wait for the bang

Years ago a mate taught me the screwdriver on the ear trick to isolate rattly bits. I thought he was having me on and it may not be perfect and with a boxer. You have to watch for getting the s/driver jammed in your ear! It worked for me on the TB front though.
Get s/driver and stick end on TB and handle to ear and rev a bit. My RH one sounds like a woodpecker, though its not too bad to the "normal" ear. The other trick of opening the throttle with engine off and seeing if there is any play also seemed OK to me.
Good tip about Steve Scriminger though. Seems a grand chap but I will let him fix my gearbox first, ahem.

Thanks for that - that's next on the list then! I'll give it a go this morning.
Well, that Steptoe bloke is a real gent.
Took the bike over on Saturday, Neil PMs me on Sunday having gone out to test ride it. Looks like I was being an old woman - sounds right for a 50k 1100, says Neil. The rattle I was so worried about was the throttle body all along it seems.
After all that, Neil won't take a penny for his time either. A proper gent.
Now, where's the "I feel stupid" smiley?
