Default Lowering the detachable HD windshield without cutting it

I figured out a way to lower my windshield height without having to go at it with a file and saw and thought I'd share this fairly easy mod. The way the HD detachable windshield mounts on the Custom doesn't allow for much room for adjustment. In particular, the lower triple tree was in the way of me getting the shield right where I felt it should be. I wanted to lower the windshield, because the top was directly in my line of sight creating a bifocal effect and causing me to slouch more than I would otherwise. I tried moving the windshield clamps below the triple tree on the fork as an experiment. The result was a little too low to be effective at highway speeds and made me nervous about the fork lower hitting the windshield clamp if I hit a big bump. The headlight cutout was also pressing down a little too hard on my headlight. I found some threads suggesting that cutting the windshield wasn't so difficult, but I really didn't want to risk bungling it and ruining a perfectly good windshield. So how to go about lowering the height of the shield without cutting it?

Basically, I removed the brackets, tied a string between the clamp holes to get the center line to keep the angle the same, measured 1 1/4 inches up and drilled a new hole with my cousin-in-law's drill press. I was hoping to get 1 1/2 inches in order to allow a little more room for adjustment, but as it was, 1 1/4 inches put the holes pretty close to the edge of the brackets and was as far as I wanted to go. I measured and measured again, but one of the holes ended up about 1/16 inch closer to the edge of the bracket than the other, so I guess I should have measured three times. Another 1/16 inch and it definitely would have been too close for comfort. The side you see in the pics is the closer one. The difference is enough to annoy me, but not enough for anyone else to notice, nor enough to create any buffeting issues at speed. And I'm pretty sure there's still enough metal around the bolt to keep the bracket from breaking from the force of the wind. The final result gets the shield low enough for me to see over it without the bifocal effect and still allows me to raise it back up, for instance, for more protection from rain, etc. It also puts the cutout much closer to the headlight than it was before with the shield as low as it will go - there's only 5/8 inch clearance now as opposed to around 2 inches, so it looks much cleaner.

This is similar to what i did to raise mine...but yours is much better executed. Someone posted a pic of the QD for a new 48 the other day, and the clamps look to have been moved closer together just like this.

Interesting approach, and well executed. Thanks for posting the detailed description and great photos!

One inch seems about right to me. It's just a general rule, though. Too low and it won't do it's job properly. Too high and it will probably be distracting like mine was. My windshield now sits about 1-2 inches below eye level depending on whether I slouch a little or sit up straight and does a fine job at that height directing the flow of air around me.

I think a good rule of thumb is that you should be able to see a spot on the road about 50 feet (or roughly 15 meters) in front of you looking over the top of the windshield while sitting on the motorcycle.

Just like CitySlicker I had to lower my windscreen to get a satisfactory
result without buffeting.

Not sure of all the reasons but 1/ the brackets on my screen are different
to the ones CitySlicker modified so drilling an extra hole was not possible
and 2/ my bike (2016 XL1200C) has a larger eyebrow over the headlight which prevents lowering the screen without cutting the headlight notch larger.

My solution was to make some aluminium brackets to move the screen forwards and down. They look untidy at the moment but now I know they work I can tidy them up, polish them & fit some nicer, cap head bolts.

girlsbike,

I like your solution. Reps to you.

Lots of posts on XLF about buffeting with the H-D quick-release windshield.

Questions:
- Before you installed the bracket, you had significant buffeting?
- Where does the airflow over the windshield hit you now?
- What is your height and inseam?

Originally the screen was just below my nose level. I found that in corners I was looking through the screen. Yes, I did have quite a bit of buffeting. I tried different positions between the two triple clamps but in the end I did what CitySlicker did & moved the bottom windshield clamps below the lower triple clamp. This was the best compromise but I found the sweet spot by ducking my head down just a little.

Obviously that position would put the lower windshield clamps in line with the lower triple clamp so I made the brackets to position the screen at that level.
As you can see I still have the option to move it up or down a little just by using the windshield clamps.

Now the airflow hits me just above my eyes, if I raise my head a little I can feel the full airflow on my visor.

No idea of my inseam but I do have short legs, I'm 5' 7 in tall.
