Windshield vent

Postby WingAdmin » Sat May 16, 2009 10:40 am



I just got a PM from MSGT-R about the windshield vent she put in her Slipstreamer windshield:

MSGT-R wrote:I just got done installing the vent from my husband's old GL1800 windshield (yesterday). That mod was long overdue! This picture shows the edges of the windshield.

If the image doesn't fit, here's the url for my bikepics page:

If you wouldn't mind, would you post how you put it in? From what I read, it's basically putting masking tape on both sides of the windshield, drilling holes at the corners, and using a fine saw blade to cut carefully through the acrylic.

How did the vent fit with the curvature of the windshield?

I'm definitely thinking about doing this with my new Slipstreamer windshield, as it is pretty toasty behind it even when it's in the low 80's now.

Windshield Vent

Postby MSGT-R » Sat May 16, 2009 10:57 am

I finally got the courage (and the time) to do what I've been threatening to do for a couple of years; grafting the vent from a GL1800 onto a GL1100. My husband used to complain in the summer that the wrap-around windshield does too good of a job keeping him in a "bubble", and the stock vents weren't helping during the hot Southern California summers.

So, I pulled out his old GL1800 windshield, removed the vent and made a template. After we were happy with it's placement, I taped off the area and pulled out my die grinder and went to work. I used my cut-off wheel followed up with the rotary file, then the hand file and the sandpaper. No need to polish the opening since the vent blocks any view of this edge. I had to bevel the upper edge of the opening because this windshield is thicker than the stock GL1800 (the vent has a lip to hold it in).

Now I get to clean up all the plastic dust that is all over everything! :lol:

That's really fantastic...I've only just put my Slipstreamer windshield on this winter, and haven't had it out when it was more than about 80 degrees. I have a strong suspicion I will be looking to put a vent in mine this summer, however. Can you feel a significant amount of air coming through it when it is open?

The template on the file folder paper was traced from the vent hole of my husband's old GL1800 windshield after we removed the vent (I kept it after replacing his with a larger one). I cut out the hole, then taped it to the Slipstreamer where we wanted to cut. I straddled the front wheel and he sat in the seat to confirm the position (fold the template in half to confirm centerline). I put painters tape across the hole in the template, and also in the area on the backside to prevent chips while I was cutting.

You can use a drill and a jigsaw, but I have an airpowered diegrinder with a cut off wheel and a rotary file to speed the process. The hand file and sandpaper are for final finishing. The blue-thing in the photo is the piece that was cut from the windshield by the cut off wheel.

Then came the "nerves of steel". When cutting freehand, I made sure I was not only square with the surface (for a straight cut), but I cut inside the marked line and followed-on with the rotary file attachment. My husband ran for cover in the house when I began making air tool noises and lots of flying plastic debris.

As far as air flow goes, I'll find out this morning when we ride over to the pancake breakfast and car show at the ball park. If I still get a wind "burble" at my back, I may cut a few inches off the top of the windshield as well (it's huge even for a 6' guy).

Okay I'm back from our ride

We went to the ball park and did some "circles" and generally fiddle-fartted around before heading for Cycle Gear and the freeway.

The addition of the vent greatly dimished the burble effect of the large windshield. The breeze was very welcome on our 100 degree ride.

The mod is a success! :lol:

I'm curious about this burble - I have the identical windshield on mine, and the one thing I have noted is that there is virtually no wind whatsoever - no burble, it's completely still - from where I sit. My wife, when she rides behind me, also reports that the wind and buffeting has been reduced considerably.

Where were you feeling the burble with the windshield?

Did it make a big difference in cooling air? Like yourself, I ride with full gear all the time, and when it's hot out, it can get quite toasty! I have Baker wings on the sides which definitely helps (and makes an even bigger difference when it's cold, deflecting the cold air away - especially at highway speeds).

Big difference in cooling now with the vent. Being short (5'1"), the breeze hits my neck. A "normal" sized rider would get it in the chest area.

My 6' husband didn't feel the burble either. Maybe it's because of my size and that I'm sitting full-forward that I can feel an eddie that pushes against my shoulders from behind at freeway speeds. The large winshield on my V65 does the same thing. When I change it out for the shorter one, it goes away (but it gets noisy).

I rode to work this morning, and while on the freeway, I moved around to try to feel the burble - I felt a bit of turbulence on the top of my helmet, but I've always felt that (I'm also 6 feet). Other than that, no burble.

But I think I will definitely look into putting a vent into the windshield.

Today, I'm in Denver (from Southern California), and I can definately say this mod is a very good thing! I'm very glad I had that vent across the desert. I did shut it across Vail pass though.. :D

I did have one problem between Parachute and Rifle, but it wasn't related to the vent (I ran out of gas). I flipped over to reserve and nothing happened! That's a first. My husband rode ahead for a gas can. :oops:

Have you switched it to reserve before with gas actually in the tank?

Yup, I had done it the day before with no problems..

Switched it straight up, pulled full choke (gets it through the stumble) and it died anyway. Tried cranking it and it wasn't coming back either. After putting a gallon in it and driving 4 miles to fill it up, I put in 3.1 to top it off, so there was stuff in the bottom.

It's rainy and chilly today, so tomorrow, I'm going to try an experiment: I'm gonna switch it to reserve (with a full tank) to see if something is clogged (?)

At restoration a couple of years ago, I removed and rinsed out the tank (it had varnish in it), and there was no rust or crud in it.

I've had vacuum when removing the cap the last couple of times here at altitude. I'm beginning to wonder if the cap is at fault?

Me too, I just need to find one somewhere, at a reasonable price.

MSG-T...I just showed my (5'3") wife pictures of you (at 5'1"!) riding your 1100, and she said, "How does she manage THAT? Wow, impressive!!" :)

I got a second seat, cut quite a bit out of it, then had it recovered.

Countersteer to full-lock-right to get it off the side stand. ;) Strangely enough, this is easier with a full tank because the bike sits lower on the suspension, making it lean less.
