    Thanks for the tip, can I use a grease like the type used on the axle?

    Ok progress. I got the bike to start today yay. It only idles for about 10 seconds and will cut out shortly if I give it gas so lots of work still.

    Here is a video.

    Been posting mainly in help forums but here is an update. Didn't like how fuel was going to both carbs, seemed problematic, not sure if it was the filters or what but I did see how it all works as a whole. You pull the line off one carb and the other line off the other petcock drain is affected (can see the bubbles appear in the filter). I went with a T fitting for a single filter and I can see if the fuel gets to there it will go good to both carbs. I will tweak the setup this is just for testing now.

    You do not need to modify the fuel line runs.
    The Fuel Flow is not the issue you think it is.
    The important is to NOT place anything that will add resistance to the flow between the petcock and the float bowls.
    These are gravity feed systems, and the FALL is only about 12" so not a lot of pressure is created by the gravity effect.
    Adding filters is unnecessary.
    The petcock has a filter screen internally that is all that is required.

    Honda spent a lot of time and effort designing theses bikes, I can't believe if they thought adding another filter would be better they would not have done as part of the OEM setup.

    The fact that the Petcock flows to one side or the other does not interfere with the flow to both carbs.
    When the Float for one carb shuts off the flow it will switch to the other carb and vice versa. The switching happens extremely fast.

    Try riding and shutting off your petcock.
    You will find you can easily go 1/2 mile or more before the carb bowls run dry.
    I do this all the time when I'm arriving at my destination (home or where ever).
    I intentionally lower the fuel level in the carb bowls when I park the bike.

    Those carbs would be happy in an ultrasonic cleaner full of real carb cleaner. Judging from your pics they're never going to run well with just a spray can cleaning. Idle air passages are really tiny, use fine wire to run them through after the ultrasonic, compressed air dry then use the can of carb cleaner to watch fluid blow through all passages. Your prob sounds like idle passages and idle jets being compromised. I think those jets are in a plastic piece/lock in the carb? I'd suggest comprehensive kits, not just gaskets.
    Excellent theme song btw...!
