MCCT adjustment video - does this sound right?

Can anyone tell me if this sounds right:

With the exhaust leaks and new intake draw from less restriction I just can't tell what is engine noise versus other sounds. I know netmatrix01 shared his overtightening MCCT destruction story and I want to avoid that!

Does this sound okay to run the bike (@ home only) until I re-jet and get exhaust gaskets replaced?

Once I get it tuned in right. I will do the JB Welded 6mm nut on inside housing.

I think I heard the clacking start at 50seconds. You were then overtightening it seemed like.

When installing the MCCT, it should JUST be touching the chain guide. You can feel it when manually turning the tensioner when it makes contact with the guide

Start the bike. It should still clack from that cyl. Use a screwdriver as a stethoscope (this is the big thing), Even with a bunch of other sounds it is 100% identifiable.

Slowly turn until clicking goes away, no more than a 1/4 turn after noise dissipates. Blip throttle makes sure it doesn't clack then.

A little more progress. For the first time since I tore engine out I got to drive around the yard for a while.. better than nothing.

I can now discern the clacking sounds very clearly versus the other taps, ticks etc., I ordered exhaust gaskets but am wondering how calebj got his so smooth and quiet after his MCCT conversion (awesome vids for comparison in "my acct conversion thread" thanks for posting those man!

It does sound a bit clacky. Where is the sound coming from? use the screwdriver to pin point a location

Its general noise from the top end, i think near the cams/rockers/HLA. Screwdriver does not transmit anying obvious to me :-( mote like constant "grinding" bad word i know. Maybe its the lifters?

I did not bleed my HLAs as it was not recommended to by an extremely knowledgeable member i trust. I could not push any of them in at all prior to rocker install.

The little flat springs on rocker arms i torqued right but am not 100% the angles are perfect (orientation is definitely correct though). Bike seems to run fine and have power.

The VN engine isn't very quiet, there's a lot of mechanical noise. Could just be the lifters as you note. The angle just made it kinda loud but mine will sound like that at a specific angle too

I noticed my rear cyl. Mcct is adjusted quite a bit further out than the front (3+ threads more) Is this normal?
