I found out a spark plug change on an ST LIMITED YOU DO NOT NEED TO MOVE AIR BOX . buy removing air filter housing you can reach the left plug. long extension and a 5/8s spark plug socket and you are good to go . I check with the dealer and they say 175.00 for labor plus plugs
Have had bikes with tough plug removal issues and found that if you drill a small hole in the plug socket and slightly into the long expention you can secure the socket to the extention. I tapped the socket so I could put in a screw. Nothing worse than having the socket come off in there and then having to take even more stuff off to able to remove the socket... 20180925_155957.jpg

I not only replaced the plugs but the plug wires too. Routing the left plug wire was tricky but well worth it as the BajaRon wires don't produce the static I heard in the headset.
I use a pair of plug cap pliers to remove the plug caps as I couldn't pull them off normally.
this is what i use to change plugs on my 2010 rts can be all done from left side the hardest part is getting the plug wire off front cylinder, when you put plug wire back on put lots of dielectric grease in plug insulator .the extension, universal and socket are all held together with red locktite tighten plug with a regular ratchet on torque wrench
