Also might be the damping rubbers on the clutch basket not the primary chain, quite common to hear of those starting to go after so long. There was someone who could supply new rubbers for the basket but not heard of them for a bit.
When you first started the bike after the rebuild did it have any rattles? When the revs drop the rattle gets worse does this point to the primary chain?I would of replaced the primary chain while it was apart but because it was quiter before the rebuild I thought it was OK, wasn't expecting it to go loud. Would the higher compression make a rattle louder or would it make no difference?

Would the higher compression make a rattle louder or would it make no difference?Nope, first start up after rebuild it didn't have any rattles at all. My old primary chain had about 5k life left in it but only had a very minimal chain rattle at low revs. No idea if higher compression would make the chain rattle louder but logic tells me it shouldn't make a difference.Hard to equate your engine with his though Julie, yours was a full engine apart strip with all the chains etc replaced IIRC, his has reused all the chains and that's where most if not all of the noise comes from.Higher compression shouldn't alter the engine BUT if the engine wasn't running well on the old bores then fixing that problem would mean the engine balance would change, so carbs etc would be out, causing more noise as it's now unbalanced.
