This one will do , see the length of the socket

the problem tho is that idk it will fit into my socket wrench

 

What size is you ratchet and extension

 

I think 3/8 inch

 

If its 3/8 inch drive that socket will fit , its also 3/8 drive, but measure across one of the flat edges of your socket ,that will be your drive

 

yea I think it’s 3/8 because I got this kit and they fit on my ratchet and the kit says 3/8

 

Then that spark plug socket will fit

 

Also one way to tell if it's a spark plug socket, it should have a black rubberish insert inside the socket. This insert holds on to the plug after its been screwed out all the way until you get it all the way out of the well.
There are 2 basic spark plug socket sizes, 5/8 and 13/16. I'm pretty sure you need 5/8.

are they bad

 

Yes. An engine in good health will have nice copper brown plugs. Yours are a bit sooty meaning rich fueling mixture. But I am more worried by the oil residue I see on them. Did they have oil on them or the camera flash is confusing me? You have reams of internet pages written on how to read spark plugs(don't have to be motorcycle specific), look them up.
