Hydraulic clutch is hard on my left hand
Getting old and the hydraulic clutch on my 2018 street glide is hard on my hand specially on stop and go traffic. A friend suggested to get a PSR adjustable clutch. You guys think an adjustable clutch will help?

I have not tried the adjustable levers. However I have installed both the Mueller and the Rekluse slave cylinders. On separate bikes. Both work extremely well. Less than half the original pull effort. As a bonus it will move the friction zone closer to the grip.

You just need to upgrade to an aftermarket slave cylinder. All will be fixed, I promise!
Many of us have done this, and mine was so bad it was the first mod I performed when it was new.
I went with Muller slave cylinder https://www.fuelmotousa.com/i-238990...lwaukee-8.html

Another vote for the Rekluse slave cylinder. I had similar issue with hard clutch pull on my 2014 StreetGlide and the Rekluse really helped.

I have a modified lever on mine. I’ve used that, and also ridden with the Rekluse slave. The lever is a bit stiffer than the slave cylinder, but both are much easier than stock.

I have a 2014 Street Glide special and thinking of going the Rekluse route.
As best I can tell the only real difference in them is, Well to try to keep the rebuttal comments a low as possible
I will shorten it to what matters most to me:
Muller Hydro Clutch (SKU 120-50)
Best For: Maximum reduction in clutch lever effort (easiest pull).
Reduction: Typically claims a 35%–45% reduction in clutch pull effort.
Rekluse Manual Slave Cylinder (SKU RMS-2415051)
Best For: broader friction zone.
Reduction: Typically offers a 20%–30% lighter pull, though it can feel more significant when combined with other adjustments.

Contaminated fluid also makes it slightly hard to pull. Can't remember but few years ago shop used one of the different spacer in the clutch basket it improved a little.
Recently I change the fluid with low viscosity dot4 used in modern European cars also made slightly easier pull or could be just my head.
