Nah, they don't help performance wise, I'd just run the hoses out to direct anything away, or like I did on my CX crank case breather a short hose and small filter to catch anything that may burp out.

Good idea. Got a link to the small filters or name/photos?

Totally unnecessary to put filters on the carb breather hoses.

Ok, I didn't look them up but I'd trust Doc to know. There are different ones on different bikes that do different stuff.

Can I just take them off then as there is the pods there they can just breathe fine without the 10" leads right?

the hoses are there to prevent crap from getting in your carbs. I have heard on the 550 if the hoses are routed so that they sit in the air-stream on the high way it will over pressure the float bowl leading to a lean condition. Its ideal to route them up under the tank into dead air, or to tuck them behind the engine case

Sam, those are the carb float bowl drains. these are what you would drain before storing the biek for winter so the gas doesn't turn to varnish over the whole winter.

there are carb overflow vents that are the plastic T's in between each carb body.

Got some damn leaks on the tank. But I Rode the bike to the office today! Test ride really. Had a few hiccups. Fuel on "on" after warmed up will not feed the bike when I roll the throttle. Sounded like it starved it as soon as I pulled the throttle. Had to drive it all the way here on "PRI"(prime?). Just ran high on idle. But lights work and brakes work! 😂👍

Anyone know what would cause that?

Thanks! Would I need to take those bowls off every season? Not sure how I would drain those.

Also, I turned the lines that were between the cards (only two) up and tucked them above thinking it wouldn't need to drain anything just breath. Should those be going down not up?

Sounds like a fuel tap issue. Does your tap work by taking vacuum off somewhere to open the tap while in the "on" position? Could be leaking vacuum so not opening tap fully. Or a faulty tap seal. There's a diaphram in the tap that might be leaking.
The prime position is just opening the tap without needing the engine running to create the vacuum.
