Apologies up front if this 'Appendix' idea goes against the 'the only one' theme of the main Windscreen and Buffeting thread... I'd be happy to move this topic into that thread but it is getting a bit long... so didn't want to clog it up. Happy to rename this if inappropriate too.

Following on from my initial post here.


Herewith my guide to making your own Air Flares for the Glee:


Disclaimer - this is free advice and probably worth every penny. Please don't melt your bike and/or create something that distracts you and makes you fall off it at speed (or stationary for that matter!)... or anything like that. Oh... and please don't blame me if something goes wrong. I'm quite brave around the workshop although with no appropriate training. I've learned by trial and error and might be underestimating how easy I thought this was, or what a risk I took pressing (reasonably) hot Perspex to the plastic fairing of my prized Glee. I've never worked with Perspex until now... if that helps... but I've used a jigsaw and drill before. I wear eye protection these days too :thumbup: and so far so good. No Glee was hurt in the making of this article and there was no blood, burns or blindness suffered afterward by anyone involved or standing nearby. :fineprint:

WARNING: The design isn't perfect and you will need to somehow protect the plastics from being scratched when riding and the air pushes the Air Flares inwards toward the fairing. I'm still trying to figure out a permanent solution (ideas welcome!) but for now I'm using rubber sticker discs normally used under furniture. Glass protector buttons also work, and with one prototype I stuck foam rubber all along the edges, which really protects everything... but doesn't look too good.


What you'll need:

- Longer bolts than the ones in the fairing. I used ones about 50mm / 2" long. There is a limit to the length. If you feel around inside the fairing you'll realise there's something metal there that will eventually get in the way of the bolt if it's too long.

- Paper or cardboard to create a template.

- An A4 (roughly) sized sheet of Perspex or suitable material - I got mine from a signage company - just walked in and asked for an off-cut... cost - $0

- Suitable saw to cut out the shape

- Sandpaper to smooth things around the edges

- Plumbers torch or heat gun or some such thing with which to heat up the Perspex so that you can bend it. Lots of 'how to' stuff on YouTube... it surprised me how easy it is if you have a torch. I wouldn't be surprised if you could do it with a candle and some patience.

- Drill to make mounting holes. I used about a 6mm wood drill bit (I wanted the hole to be larger than the bolt to avoid stressing the Perspex).

- Rubber spacers / washers. I used a thick, hard rubber tap washer, surrounded by soft (old bicycle inner tube) cut outs, plus a metal washer on the outside.

- Something to protect the fairing from the Air Flare rubbing against it. As per warning above.

- A sip of good ale really helps now and then :yesnod:


Step 1:
Start out with this shape

Image


Step 2:
Transfer this shape to your choice of material.

I tried with a thinner Perspex first, then opted to go with this 3mm stuff. There are pros and cons to the choice, around flexibility, durability, etc. My bike is garaged day and night and mostly on tarmac. They are pretty easy to make once you get the hang of it... so try different thicknesses and see what works best for you. I'm not sure if this methods works on anything other than Perspex though. So please do some research on how to bend other materials before simply aiming a flame at it.

Tip: Try leaving the protective film on to prevent scratching until you use the heat gun... then it needs to be off.

Tip: Make a few extra templates. Once you've bent them you'll realise how impossible it is to copy them again ;)

Image



Step 3:
Cut them out with a metal hacksaw / blade (or better if you know how). My jigsaw on medium speed worked OK.

Cut slowly, and watch out for heat buildup. The Perspex will likely melt here and there along your cuts. Sometimes it re-connects to the other half and bonds so strongly you have to cut it again :headbang:

Try as far as possible to keep the material steady and avoid too much vibration/flexing. Just when you think you've finished with that last little bit to go, it might crack and you've got to start again :jawdrop:

Image


Image



Step 4:
Sand down edges by hand or with a sander. The finer the paper the cleaner you'll get the edges apparently. I just used standard '60' gauge sandpaper that came with my sander.

Image



Step 5:
Remove fairing bolt and store somewhere safe. You'll need to use a longer one if you're going to use enough rubber spacers to reduce vibration and permit some flexibility. See 'What you'll need' above.

Step 6:
Make sure you know where you want to position your Air Flare. I put these stickers on to show what I was lining things up with to try make something that kinda fits the lines of the fairing.

Hmmm... seems I've reach my limit of file attachments. Follow on post coming up!

Mimo - what are you asking for the deflectors, including US shipping?

BTW, love the polka-dots! I wouldn't do it to mine, but about the most unique paint I've seen on a V-strom!

Hi G-Dub,

Expect to see a post in the Inventors/Group-buy forum by this Sunday, and don't worry, US shipping will be fast and free.

Thanks for the compliments on the spots, they are actually green vinyl circles applied over the standard pearl white paint.

Installed the deflectors from Mimo256 (came in the mail today), and took it for a quick run up the highway...
They do smooth out the air... Worth it, for me...

I just did a quick install and test of the augustus deflectors and agree that they appear to work well.

Someone else had mentioned that these deflectors reduce the airflow to the chest area that increased after installing the givi airflow - and I agree.

These deflectors with the givi airflow seem like a great setup - I am looking forward to putting some real miles on to try it out further.

DIY mirror brackets -- reduce wind

Below, are pictures of my DIY mirror mounts. I am sure that they are not 'original' but...
They are made from 1/4 X 1 inch aluminum. I experimented a bit and found that having 2 1/2 c-c hole spacing gave me the desired effect. The parts included 10 mm bolts with lock washers and spacers made from 1/2 copper pipe. Takes about 10 min. to make them.
The wind effect was pretty dramatic. Before the new brackets, I had a strong wind coming off of the mirrors that hit on each side of my helmet. Now, there is a quiet space of air for about 3 inches on either side of my helmet. The view in the mirrors is really good now...also.
(a couple of ergonomics....I am 6' 2" and have the 2 piece GiVI windshield.

I'm 6 foot even 33 inch inseam. Stock windshield on lowest setting. Mimos deflectors . I'm very satisfied with this setup up to 75 mph when turbulence increases but still tolerable. Thanks Mimi.


Thanks Mimi

hey Mimo, got these yesterday in the mail(thanks for the super quick turn around!). put em on right away and ran up and down the highway. VERY impressed. i no longer find myself wishing i was two inches shorter. the buffeting is pretty much gone. for the record - 6'1" with 34" inseam, vario adjustable windscreen in the highest position as well as in the highest mounting position.

money.well.spent.


thanks Mimo!

They really work!

Who would have thought redirecting the are flow down there would have such a difference up at the helmet. I made a pair for myself and work fantastic. I would recommend for anyone battling buffeting (which you will on this bike) is to add these winglets before making any windscreen choices. It summer right now so stock screen on highest position is fine with be right now. Buffeting is 99% gone for me with stock screen.

Augustus Deflectors Review

I'm 5'7" with a 30" inseam. I am running the stock windscreen mounted in the highest position. I am also running the stock mirrors, but they are mounted on Richland Rick's mirror extensions.

I've been running this config for over a year. I purchased and installed Mimo256's Augustus Deflectors. This past Saturday was my first ride with them.

Wow, zero buffeting. Mimo265 nailed it.

My ride Saturday was mostly gravel and fire service roads, but I did hit a bit of interstate ( up to 80mph ). I was amazed at being able to hear not only the engine, but the chain, and the tires roaring ( Shinko 705's ). Once I met my OCDWill and we ventured off the pavement I removed my ear plugs as they were no longer needed.

I'm short at 5'7". On the interstate, when I crouched down about 2", the cockpit was silent ( even with my helmet shield up...crappy DS helmet that is very loud - but vents very well in the hot, humid Atlanta temps ). When I straightened my back, it put my helmet right in the air stream. Enough to full the vents and keep me nice cool.

Best ( and cheapest ) mod to date.

Thanks Mimo265.

Second this.

As of last weekend, I was running the Givi Airflow and Adventuretech mirror extenders and still experiencing enough buffeting to be dissatisfied. I'm 5'9" with a 30-in. inseam. I ordered the Augustus deflectors three weeks ago on a Sunday and they were in my mailbox four days later. Excellent turn around time. After a longer bout of rain, I mounted the deflectors up yesterday and went for a three-hour ride. Wow! What a difference. There was almost no buffeting. I say almost because I was also testing out a new helmet with a visor, but still, the buffeting was almost entirely absent. I had my face shield up at 70 mph and was catching no wind at all. Not smart, I know, but I wanted to "see" it for myself. Thank you, Mimo265! You've created a tremendous product and changed my riding experience.

Deflectors really do work!

Shortly after getting my 2012 DL 650 I put a set of SW Motech light brackets with some round LED lights on the front cowling area. I noticed right away that these helped with turbulence coming off the tank. So, I thought about that for a while and came up with some Lexan deflectors that I attached to the light mount points. These helped even more. I did reduce the size a bit and they seem to work just as well. Here are a couple pics of those for reference.

After doing some more work with the windscreens I kept noticing air coming off the mirrors when holding my hand up to see how and where the air around my helmet was coming from. I didn't want to replace the mirrors as I think they are some of the best stock mirrors made for rear visibility. I bought the mirror extenders and set the mirrors out to each side a bit. Didn't make much difference. I could still feel the air off the mirror so I fabricated a lexan panel going up the side of the mirror stalk and inside edge of the mirror housing. I thought this would block the air off the mirror.... Well, it did. But, it made it go a different direction. Directly onto my helmet! I knew 2 miles into my test ride this didn't work. Next I tried to change the mirror extender angle. I found they worked best moving the mirror almost directly to the rear. That is better, but I still feel some air from the side. Especially in cross winds and traffic. I hold my hand up beside the mirror and find that when my hand was at right angle to the mirror it made a big improvement. It didn't try to block the air, it just cleaned up the airflow and gently pushed it past my helmet. You can see the deflectors move when they get a blast of turbulence from the side, but you feel very little of it. The first set I made from acrylic which developed cracks at the mount. Made some from Lexan and all is good. An angle with the rear slightly to the outside works best. Yes they look flaky to some, but with the new windscreen setup I have the air management is outstanding.

Wind, wind & less wind...

Ok, so I've been reading the posts about wind buffeting and noise and I have never really felt a huge amount of buffeting or noise.....until I read the bloody posts and then I IMMEDIATELY started feeling wind EVERYWHERE! So...I saw the posts by the S.African bloke and wanted to make a pair of wind deflectors for my '13 650.....except I'm too bloody lazy! So I checked in with California Scientific from whom I had bought a windscreen and they told me I was crazy. They had made some deflectors for a bloke on an '07 650 and had no luck with wind defection. I insisted so Mark, the owner said, "ok, come by and we'll try something out." Luckily, they are based in Sacramento, which is only 1hr and 45 mins away so I went up there and they fitted some mock-ups on my bike. I rode around a bit and they knocked down the wind about 80%. BRILLIANT! So Mark made some real ones and I went back up a few days later, he installed them and off I went. Awesome. No more wind on my waist, rushing up and slamming me under the chin. No more serious helmet noise. I can now hear the engine purring. I never go anywhere under 80 miles an hour and put about 2000-4000 miles a month on my bike and they have helped a LOT. Mine are made of 3 mm plexiglass like the windscreens but the ones you can buy are probably going to be made form 1.5 mm plexiglass. I'm 5'8 and 165. They aren't the prettiest things in the world but so what? The bike itself isn't exactly the Scarlett Johansen of bikes. Of course, after only 3 years, they're redesigning the '15 650 so I may have to go through all this again next year! They should be available from California Scientific right away.

I've found a new application for the Augustus Deflectors (from Mimo256). http://www.stromtrooper.com/group-b...rooper-inventors-product-showcase/189785-augustus-wind-deflectors-sale-now.html

Up top on the upper edge of the bodywork, using the two factory screw holes.

If you go back to my earlier post in this thread http://www.stromtrooper.com/dl650a-2012/81897-winglets.html scroll down a few posts.

I'm trying to eliminate the blast of air that is coming up under the corners of my windshield. Windshields with wider bottoms, like the Givi, Manta and others would not have this problem.

I just had to drill a new hole 1 3/8" up from the original and the screw and space bushing worked just the same as they do in the original side mounting. I then cut off the excess part of the tab with my dremel. A pretty simple operation.

It's made a nice difference, gone is that blast of air that came under the corners of the windshield and hit my upper shoulders, that flow has now moved outward about 3" past the side of my shoulders and the wind noise in the helmet is also significantly reduced.

Two thumbs up! :thumbup:

In their originally intended position. I recently mounted some LED driving lights on the SW Motech brackets and the Augustus Deflectors no longer fit.
