"They all do that sir"

Has something to do with the cam chain tensioner, being hydraulic it take's a few seconds to take up the slack in the chain.

rattle

if mine only rattled on start i would be happy, start up on hot sounds dreadfull, knocking and rattle, get all sorts of weird noises hot and cold, but then again it has'nt got a fairing round it . if you've had a jap bike you've been spoilt, try a triumph triple , sounds like a diesel when hot.

Replace Lh Cam Chain Tensioner

I fitted the latest ( 3rd generation?? ) LH tensioner parts a few months ago - completly eradicates start-up rattle - cold, hot or very hot!! - absolutely brilliant, bike also very quiet at tick-over or in town when hot. More info can be found on the link below, I think I've listed the latest part numbers and links to ADV site photo guides on my 2nd reply on that post?:-

Please note the parts listed were ordered from my local dealer no problem and don't be swayed by discusions about different oils - a heavier oil make your problem less obvious, but it's only camouflaging the underlying design problem - otherwise BMW wouldn't have changed things?.
