How to tighten cylinder nut

How am I supposed to tighten the nut shown on the image? I can't fit a wrench there to tighten it, nor a socket or a pair of pliers. Right now the nut is at the bottom but is putting zero pressure on the cylinder. On the other side I cant torque it but it is hard tightend. The others 2 nuts that are on the front are both torqued.
Does it matter that it has zero torque? How should I tighten it

Torque is hard on those without special tools. I had to grind down the outside of the 12mm wrench to clear the cylinder head. On one of the cylinder I had to use my Dremel tool to make some room around the nut for the wrench. I use the same wrench on all nuts so I am consistent with the feel/torque.

To get one off that does not have clearance for a wrench, you can use a flat nose punch and a hammer to hit the outside flat of the nut to get it free.

Yeah I was thinking of grinding down the side of a 12mm wrench. I asked my dad but he said no. Ill try to buy one more and grind it down and I can see if that works.

I was taught that any smaller bolts get always get torqued after the main cylinder studs/bolts. So as not to load up the threads in the alloy and risk them pulling out.

Look at several manufacturers of wrenches as some are made with a smaller head. Also check to see if the nut is for a 12mm wrench or socket. Someone may have replaced with one that takes a 13mm or 14mm head.

I have a nice thin walled Bahco 12mm ring spanner that works nicely on the 300, the 125 is clearly a different arrangement but they must have designed it so it was possible.

Test your feel with a torqued 12mm head nut or bolt somewhere non critical several times till you get the right do/undo feeling and replicate on the cylinder fasteners little bit at a time so they are all even which is most important.
