Now the bike is almost finished, just needs the seat covered and tyres, so I put on my glasses and cast a critical eye over it. Story of my life – never, ever happy, and what do you know, I found a few things I’m not happy with, so, I can start making parts for it again, whoo hoo!. First up was a new spin on filter/cooler. The current one totally underwhelms me: hoses look untidy, the spin on filter mount looks too blocky, so, that went in the bin. One of the screws holding the mount to the engine bracket was a bit hard to get at, so, the right engine mount went in the bin. The cooler bracket is just plain terrible, didn’t like the mounting method nor the look of it, plus the rubbers I felt were too small, so that also went in the bin, along with the left engine mount.

So, back to work: first up was a new spin on filter mount, I put a little shape into this one: rounded the edges, turned a cone on top and pressed the inlet spigot into the side of the mount, so the outlet hose from the front of right engine cover is only around 4’long and attaches to the inlet spigot of the spin on mount on the side, just in front of the engine mount. Much more neaterer!

Next came some new engine brackets. The spin on mount is still mounted in the same manner, just set further back, so, the engine bracket protrudes further back, almost touching the engine case. This allows the rear allen head that was hiding behind the down tube to be moved further back, so now it is to thebrearnof the downtube and thus easy to get at.

Next came the cooler mount, the original I made was a piece of 3mm ally, bent at a right angle and bolted to the front of the engine brackets via four allen heads. Didn’t like that, so I extended a goose neck on the front of the engine brackets out about 30mm and drilled and tapped holes in top for mounting the cooler bracket.

The cooler bracket, is now just a flat section of 3mm ally, with larger holes drilled to take bigger, thicker gromets and is secured to the top of the engine mount goose neck protrusions via four stainless button heads. To mount the cooler to the bracket I spun up four threaded T nuts that are inserted into the gromets from underneath and the four long bolts secure the cooler to the top of the bracket. The T nuts prevent the gromets from being squished too much.

Now I just have the one long hose over the engine bracket connecting the cooler outlet spigot to the right engine cover. A hose connects the spin on mount spigot on top to the inlet on the cooler. I’ll retain the black rubber hoses as I don’t like the look of braided hose: to silvery and hard to keep clean down there with all the road debris and the black hose is a little less intrusive.

Looks good I really like the oil feed from the motor. I find a bit of reflecting on how a job could have been done better is healthy. Sometimes I start again, othertimes I promise to do better next time.
 
I' m thinking of drilling a hole through the rear of the right engine mount and feeding the return hose through that to the right side filter cover.

Very elegant setup, thinking.
I'm not quite clear on the oil line routing.
I like your modified side cover line fitting. Have been thinking along the same lines, the filter, cooler is an area on madness that I'm not happy with.
I reversed a cover to get more meat where the line exits, unlike yours, it's still a jury rigged looking set up.

I used 10mm hose, but I made the barbs 11mm. Easy enough to push on with a bit of oil, but a real bugger to get off. Should have made the barbs 10.5mm. The XS lube system is very low pressure, so, I don't see a need for high pressure fitting, at 5-15 PSI I don't think the hoses are going to come off.

I was going to cut into the side cover for the inlet, as you've done, but baulked at cutting up the side cover It does look need though!

I'm working on a clamp for the engine inlet hose, keeping it parallel to the frame down tube so its less noticable.

On my system, oil exits the front of the side cover and enters the spin on via the barb in the side of the spin on mount, then exits the filter via the barb on top and is fed to the left inlet on the cooler. Oil then returns to the engine via the hose on the right of the cooler.

I see you have your cooler inlet outlets facing down, I reversed mine so the oil doesn't drain.
 
I wanted a cooler like this one I used on my Bonny. Inlet and outlet were just siimple tubes onto which you pushed the hoses, a good sturtdy design. But, no longer available apparently.
On another note, look at the Norton filter mount and how it's attached to the frame. It's a clamp off a floor polisher!

Eewww, never seen anything someffing ugly. Not on my bike!
The Trident one looks a bit wide for the XS.
The one I have has a small leak. The bits on the side to slide bolts through for securing were both bent inward slightly, I attempted to straighten them but in the process must have separated the cooling fins. The unit is coated with really hard plastic/paint/whatever and just that little bit of bending cracked the paint/ plastic and it started chipping off.
I have been looking at heat exchangers on ebay and aliexpress, some of them look promising
