I don't see the benefit of a windshield vent on a spyder. It may work on other motorcycles. On the spyder the way the air comes up off the frunk lid under the windshield it just pushes the vented air up the back side of the windshield. I don't get any air on me doesn't matter how fast you go. The faster you go the harder pushes the air up the window. (Obviously)If you're going slow it doesn't push any through. If you put your hand there it's not hard to see exactly where the air is flowing. Waste of money in my opinion plus it's a real pain in the neck to clean around!

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Windshield vent useless?

Get yourself some BAKER AIR WINGS then you can direct all the air you want

I have a f4 and yes the faster you go the less you feel it . Now close it and see how you feel. The vent works. Just on really hot weather not much is going to help when you are sitting on top of a hot engine and the sun baking you to death.
Now I keep mine adjusted all the way up too..But I do feel the vent air , not so much at 75 + mph. :shocked:

Do you currently own an F4CUSTOM windshield with a Goldwing vent on your spyder?

Possible air flow improvements
.
I have a vented windshield ( from BRP)on my 2014 RTS and it works. The air that comes in from the vent fills the low pressure area behind the windshield ( any windshield ) forcing the bubble of still air up and back. Just ask your passenger. This also pushes the turbulence up higher so you don't feel the head shake. No , you don't get a blast of air as though there were no shield at all but there is fresh air coming at the ryder. Maybe a more open faced helmet or adjustment of the vent slats may help. You could also try to temporarily attach a small air dam along the top edge of the vent ---- creating a high pressure zone at the front of the vent. Three possible solutions.
Some aftermarket manufactures may not have the facilities or an understanding of aerodynamics Or some are just to cheap to do it right. I've modified a few ram-air / cold air systems and air boxes for actual power increases and even made helmets breath better. So try and think outside the box--- try my 3 suggestions. No guarantees but I hope one of them will help you out.

I tend to share Lew L.'s observations. The only vented windshield I have experienced is my Goldwing. Not a stock windshield, but a Tulsa "Tall". Although the windshield does a wonderful job of directing the air over and around me, there is a vacuum formed behind it, which tends to pull all that re-directed air directly onto a passenger. Open the vent, that vacuum bubble is extended to behind the passenger. The vent is not so much for a direct blast of air as it is to relieve the effects of that vacuum bubble.
You do not mention which Spyder you have. For the '19 and older RTs, the BRP adjustable deflectors (below the mirrors) do a decent job and look a LOT better than Baker Air Wings. I have had Baker Wings on other bikes and agree they do a wonderful job, but their aesthetics do leave a bit to be desired.

Might consider taking some short yarn sections taped to the aft side of the windscreen to actually see the airflow, but most importantly, the true direction the airflow is moving.
Our 2014 RTS Spyder has a F4 windscreen with no vent. We live in South Florida, and it does get hot. Every ride is with full coverage helmets, long pants and jackets, even in the summer.
Years ago, one of the first upgrades was installing the adjustable side deflectors. A short while after that, I did away with the oem left and right mirrors by fabricating mounts for aftermarket mirrors. Both of these mods greatly increased airflow to the rider and passenger.

I have an F4 windshield with the vent and regret it every day. I should have not gotten the vent. All it does for me is make it a PITA to clean the vent out. I have been debating on selling mine and getting a new F4 without the vent.

On my 2015 RT Limited when towing the camper I would get a lot of exhaust smell, it all went away with the vent on windshield open.
Like others have said, the pasanger gets leff buffeting when the vent is open also.

Which Spyder do you have? If it's an RT the reason, I'm quite sure, that you don't feel much air flow front the vent is because of the air flow around the bike. I have an RT with the F4 tall and wide with vent. The air circles around the bike. In fact my flags on the trunk fly backwards. In rainy weather with the vent closed I get more rain on the backside of the windshield than on the front side. The vent helps balance the air pressure on both sides of the windshield but that is about all. Because of the design of the RT you will not get air to flow past you from the front except with the side air deflectors. The Baker Air Wings help a lot in this regard.
To find out what it would be like without the vent tape it shut tight and go for a ride in the rain. Then ride it with the vent open. You'll see, but maybe not feel, the difference.
