Help identifying some parts? (resolved)

Edit: Thank y'all for the responses, this is so helpful! I'm still trying to learn my way around motorcycles and it can just be hard to find information when I don't know what to google, I really can't thank you enough.

Hey ya'll, I'm a noob and I have some parts I want to look up but I can't seem to find them on the schematics on websites like Partsfish :dontknow:, wondering if anyone knows what they're called so I can get my bike better off.

The first and most important one (because it actually has issues) is this part that connects to the radiator and the cylinders to transfer coolent, the previous owner did a real number on the whole thing when he 'fixed' it by adding silicone all over instead of just replacing the O-rings, I just don't know what O-rings I need to replace these after I get all that silicone off of there....If it's not too expensive I'll just order a whole new part but at the least I need new O-rings. Anyone know what this thing is called?

for more context this is where it attaches:

This cable attaches to the front of the gear case (is that the right word?), it's cracked real bad, and again, if not too expensive I'd like to replace it as long as I already have the radiator off and have access to it (otherwise I might just try a temporary fix and hope it holds up a long while):

and lastly this one, it's gotten caught when I have taken the carbs off and it's seen some better days, I probably won't replace it because it looks like that would be a huge pain but I'm still curious as to what it is:

I really appreciate any feedback, unfortunately I apparently lack the knowledge :scratch: to figure out what parts these are, I just want to fix the leak originating at part 1 and get the fluids replaced before spring rolls around :vs_biker:

oh whoops, I'll fix those attachments... Thanks so much! I would have never guessed that was the name, you're super!

The second last photo looks like the rubber boot that covers the oil pressure sender, with cable coming off it.

The last photo looks like cables coming out from pulser unit through a slotted "boot" also. These may just need cleaning up. Don't know if you can get these. Some of the more clever members on this forum make their own when the need arises.

Aftermarket O rings are fine if they're the right size. But near enough is good enough will likely end in tears.

I don't use Honda O rings. I can outfit a whole motor with O rings for what Honda want for just a few.

I can give you the size if you want it.

Very carefully take all the silicone out of the openings into the cylinder heads and coolant pipe connections. If that gets into the engine cooling system itself it can cause problems.

I haven't found an aftermarket size that properly fits that elbow-to-head junction. Maybe you've had better luck, being in a metric market.

Here in Adelaide we are very fortunate to have a specialist seller of O rings. There's not much I can't buy. Still have to fudge on size with some, but mostly I can get exact spec.

Spec for these is 23 x 2.8. For these I use 23 x 3 and have many times. Composition of rubber will also have a bearing on whether an O ring will break a fixture so YMMV on this one. For coolant O rings I use basic NBR 70 or 90.

Your number three picture is the oil pressure sender wire and is in two sections, the longest part is what you see at the front of the engine and the short section will be up by the spine where it connects into the main harness.
The fourth picture is the wires from the stator. If you should ever have to change that, it is an engine out procedure.

All the o-rings for the coolant system should be available from Honda. Also, I always use the o-ring from a 650 motor on the chrome pipe of the cooling system, as it is tapered and not round and does a better job of sealing.
