Hi! I have some rattle and ticking on my CB400NC (Superdream 1982 model). What I have done so far: Adjusted the valves, reset the balance chain (the shaft spun freely, and the dot ended up within the margins). Adjusting the cam chain changes get rid of the chain rattle so I guess it works (seems to move freely). There is still some "clinks" and knock/tick i can't get rid off. Oil is of course changed according to intervals and level is good (oil light works as it should). Starts right up and idles nicely. Some white smoke on startup on colder days, but no smoke when warm. A slight weep from the valvecover (New rubbers under the screws, but will change the gasket in winter).
Here is a video of the amount of slack on my camchain. This is with the adjuster loosened and the flywheel on "T":

Here is how the engine sounded before i adjusted valves, camchain and balancer chain:

Sound before the last valve adjustment. With the effects of engaging the clutch:

Any insights on how to get it "smoother"?
Ps. I'm using 10W40 mineral oil.
