Tacka tacka sound is tappets, clattery rustling sound is cam chain, carbs out of ballance make it worse, not forgetting there is clutch rattle to add to the mix, they are never going to be as mechanically quiet as modern engines, so bear in mind that if you are used to riding a more modern machine the honda might sound a bit agricultural, every time I go out on mine I become convinced that it's about to explode half way around the ride, then I get back to my driveway and it's humming away merrily on tickover, so I guess all is well, I've heard quite a few CB750's that are mechanically noisy but also one that a quiet as a mouse, Bytio's Phil read replica, he had completely rebuilt the engine and obviously made a very good job of it (or were his tappets clearances too small! 😧) my advice is check the fuelling is ok (plug colour) if it is just ride and enjoy it , earplugs help 😄
PS I've heard people say that oil splashes about if you remove a tappet cap with the engine running, mine never has, the components are all wet with oil but it's not like the North Sea in there!, anyway I've done over 2k miles and the top end seems fine).

Cheers I'm probably just being paranoid .has its first engine I've built like you say oil isn't splashing around but they are covered in oil

Wow, this looks amazing. Another one i've missed keeping up on.
A real credit to you, great work. Really looking forward to seeing it in the flesh.
And I agree, 74 was a proper good year. ;D
