05 twincam noise
Hello guys. I have a question. I replaced all cam service kits (cam chain ten, lifter, rocker arm, valve seal). I also installed the rocker lock kit. Nevertheless, the cylinder head makes noise. The noise is not before preheating, but it is after preheating. The noise is more as the RPM increases.
1.What is the problem with noise?
2. Is the engine oil circulation a problem?
Please help me with the solution. 🙏
I'll attach the video.

I hear a little bit of valve train noise but not enough to bother me. Based on the video looking into the oil tank neck, I would say oil circulation is not a problem. I have a few questions though:
I see the bike is a softail; what year?
Why did you replace the cam chest parts?
Are the replacement parts the same as the removed parts or are did you replace OEM with aftermarket?
How many miles on the motor?
What replacement lilfters?
OEM or adjustable pushrods?

I hear obviously an issue maybe. Exhaust however is interfering. Put a two ear stethoscope on it to kill that exhaust. Probe head and cylinder top to bottom.
Do you hear enough bang (tap) to hurt anything? My 04 with 50k on it doesn't sound like that.
Now it did once checking the cam tensioners and made the mistake of draining oil first and bottomed lifters.
It sounded a little like that about half way past sounding like it was self destructing and OK again when I started it.
I love that shot of a electronic sequential port fuel injection in action. Ever time you shut it down, that last charge remains and if it sets, dries up and looks like oil.

A rag muffling that exhast will help. That's the difference in those two words since the FP combined two issue. A two ear stethoscope settles the issue.
Sorry if my wording on an on line is difficult to see a big picture.
I saId nothing on your post but I hear a lot of valve train issues I think. But I perfered not to post like a rounder
It's too loud for piston slap which is deeper but both can sound similar.
Not telling you this. Just how I see and interpret it for the First Poster.
Sure as a community team, you have a lot more experience then I.

Nice to meet you, I'm Softtail 05. There's less noise in the video. There's a lot of noise in the drive. I kept making noise, so I replaced them all. I asked if the engine oil circulation wasn't enough. (24197mile, All replaced with Harley, the push rod is pure.)

As for oil circulation, if you have good oil pressure and the dip stick registers close to full at operating temperature, don't worry about oil circulation; I don't believe that is a problem or contributing to the noise you are hearing.
How does the bike run now after the installation of the new parts? If I understand correctly, the motor started making a new noise which is why you replace the parts suspected of contribuing to the new noise but the noise remains; is that correct? If that is correct, I think we have to go back in time and find out more about what may have happened to cause this new noise to present. The source of the noise could be unrelated to the parts you replaced.
You did not mention the condition of the cam tensioner pads; what condition were they in and were they replaced.
