It's your timing chain tension adjuster. You need to replace it. My B4 did the same thing, always sounded like it was rattling, especially at idle. I had the tensioner replaced and it felt like I had a rebuilt engine! Smooth!

i can try that but i don't think that is my problem  if you pull in the clutch lever at idel the noise goes away release the lever again the noise reapears?and come to think of it the bike was getting harder to shift into gears at times?thanks guys so far for all the replys

It could just be the cush drive in the back of your basket is worn out. No way to sort it out other than a new basket. But it wont do any damage running it with the noise.

they are notorious for the baskets coming loose and the symptoms are hard shifting once its loose it wares on the bearing as well
