Show us your cut down windshields
« on: March 10, 2014, 04:54:20 AM »
Looking for ideas on cutting down the stock winshield, and how do you like it?
What is the air flow like?
Pictures please.

The stock 08/09 shield flows quite a bit of air, unfortunately for me, you can get some buffeting especially when carrying a passenger.

I cut my 2010+ shield down and added the Cal Si opening in it. I like it a lot during the hot months. All the way down, you get all of the air you want. All the way up and it blocks enough air so that riding on the slab you're not having to hold on as to not get blown off of the bike.

Here are some photos. One in the down location and one in the full up location.

Mine looks like the Pope's except it's a clear '08 with no cutout and 4" shorter than stock.

How does the CalSi cutout help with the buffeting on an 08/09 stock shield in the full up position?

(I should say "how well", I don't need a physics lesson)
Because turning doesn't suck.

Without going into a physics lesson, I like it.

Just did mine last weekend.  Started with my stock '12 screen. I measured about 6 inches from the top, cut, and then used the top piece to make a template for the curve.  It is still a little ruff as I need to do a little more finishing and sanding to make the cuts a little more smooth.  I like it MUCH better.  The buffeting is gone. There is much more air.  But it is still noisy.  And it still works decently well for the cold too.  The last few days I have been riding to work in the morning; average 28-32 degrees F.  I just put the screen in full up and duck down a little so my chin does not freeze.  I have yet to ride two up with it yet.

Best part: It was FREE

Cutting line with crayon, cut with soldering iron, wood rasp to equalize, sandpaper to shape the rounding, finishing with a sharp knife blade.

I started with a Dremel.  This was a mistake.  I went to a bigger more powerful cutting tool (think its called an osculating saw?).  I traced the top of the stock screen onto paper and taped it about 6 inched from the top.  Once the basic cut was made, I had to adjust the paper template when cutting each edge because the top of the screen is a little narrower (i.e. my template was a little narrower than where I taped it).  I just kept with the same curve to round out the corners.

Just wing it and it will work out!

After I covered my windshield with masking tape I tied a piece of string to a pen and held it at the bottom center of the windshield and made an arc.
I cut it with a plastic cutting blade on a jig saw and sanded the edge to finish it. If you heat the cut lightly with a propane torch it makes a nice finished edge.
I am going to paint it black on the inside. It is for summer only, full down the air hits your waist, full up air is at the bottom of the helmet.

The VICTORY bike's cut down windshield doesn't even look as good as a bald head  ;D

 With the shield still mounted on the bike, I applied masking tape to the shield. Then I measured in from the outer edges and marked the center line of the shield. Next, I measured down from the center top edge (3.75" in my cace) and placed a mark. With those referances, I place several more marks. After I had it dotted lines so to speak, I'd step back and take a look. If I didn't like something (not semetrical from side to side or just the overall shape) I'd just apply more masking tape over the marks that I wanted to change and then re-mark.
  When I was satisfied with the shape, I removed the shield from the bike and using soft jaw clamps and a protective towel, I clamped the shield down to my work table. Was only able to clamp down one side, but when I got half way thru the cut, I re-clamped it on the other side. I used a standard jigsaw (some call it an isolating saw) to cut just to the wast side (about a 1/16 of an inch) of the line that I had marked. Then I re-mounted the shield to determine if I wanted to make any other changes. While it was mounted, I mounted the bike and raised & lowered the shield to see what it would look like from the rider's possition and I even took the bike out for a short ride when I was 90% sure that I was happy with the shape. I would then decide if I was happy with it or if I wanted to make some more adjustments (round off the corners more, cut it shorter, add the Cal Sci opening, etc....).
 When I was happy with the shape and cutout, I removed the shield from the bike and used an isolating sander on the outer edges and a drimel with a small sanding drum for the Cal Sci opening to clean it up to the line. When the shape was done, I took a propane tourch and lightly flamed the edges to take out all of the sanding marks.
 As far as the tint.... sprayed the inside of the shield with tail light spray tent.
