Airflow adjustment on the 06

[weekend rider]

: A couple of sentences could have said it all;

1) heat transfers from a warm surface(air) to a cooler one(air) or air flow dierection is to mix

the hot air flowing from hot to a cooler enviroment (incoming air)

no mangement here just direction keep me cooler than thee 03, 04, 05's

the heat from my 05 keeps my chess-nuts roasted really well :yahoo:

Are you guys sure that the outboard position directs warm air further away from the rider? Or, does it just route it away from your legs and re-direct it toward your torso and upper body?

Yes, I am quite sure. The vents are way too low to affect anything above your knees.

If you look closely at how the panels are designed to swivel OUT and look at the opening to the radiators and engine bay just in front of them, it becomes very obvious that they are designed as DEFLECTORS. The mistake many make (including myself) is thinking that the vent action come from opening them outward to let heat in between the frame and the panel, but if that is what they intended them to do, the whole panel wouldn't need to swivel out like it does. The purpose of them is to deflect the hot air that comes out of the large vent in front of the panel off your legs when the panels are extended.

Another thing I noticed, is that I think I know why your left ankle gets hot. If you look right in front of the shifter and oil filter, you can see a gap all the way through to the exhaust headers. This allows hot air to exit right onto your left foot/ankle area. If you look on the right side of the bike, you will see that same gap is blocked by the water pump and hoses. This explains why the left ankle gets warm. A simple deflector could easily be fabricated to push this air away from your ankle, and in fact, I saw some sort of toe deflectors shown here on a Canadian model that might do just that.

Here is a photo of the left side by the riders ankle. You can clearly see a clean shot to the exhaust headers.

Here is the right side, where you can see the water pump blocks the air flow.

Thanks for the pics and thorough explanation, Fred. I see your point now.

Fred, Do you have an infa-red temp guage? When I first got my bike and moved em out I felt hotter. I was thinking this, " thinking that the vent action come from opening them outward to let heat in between the frame and the panel" was accurate. Can you check the temp at the frame with the panel open and closed?

P.S. Don't wreck while doin it

2006 FJR1300A/E - AIR Management System
What is the Air Management System?

The air management system is a series of new features on the 2006 FJR that work to keep the rider comfortable by managing the way that air flows around and through the motorcycle as it moves down the road. There are two main elements of the Air Management System: the first is designed to direct hot air away from the rider and motorcycle keeping the rider cool. The second is designed to direct cool air around the rider, making for a more comfortable ride at speed.

HOW DOES IT WORK?

Heat Management

The heat management system was created using computer simulation and wind tunnel testing and is based on the principles of fluid mechanics.

Part of the heat management system is the use of a new curved radiator with twin ring fans that work to push the majority of air, heated as it passes through the radiator, out the sides of the motorcycle and away from the rider. In addition, the heat management system directs cool air through a vent above the radiator. This cool air mixes with the warm air that has passed through the radiator and mixed air then passes below a new formed heat shield located above the engine. This mixed air then exits the motorcycle below the engine.

The heat management system also directs low temperature air through vents on the sides of the headlights. This cool air enters the area between the fairing and frame creating a high pressure area. This high pressure pushes the air through a cool air inlet at the front of the frame. The cool air then passes above a new formed heat shield located above the engine and absorbs any heat that escapes above the heat shield. The air then exits the motorcycle between the fairing panels below and behind the rider.

Rider Airflow Management

The rider airflow management also manipulates air pressure to ensure the rider is comfortable. Two new vents located at the base of the windshield are opened when the windshield is in the highest position. These vents feed air up the rear side of the windshield to dampen the air vortex that is formed as air passes over the top of the windshield. This reduces helmet buffeting.

In addition, a new vent located in the fairing below the windshield feeds air through the fairing and out a vent located below the instruments to reduce the low pressure area behind the windshield. This reduces the helmet pulling sensation that most motorcycles experience when the shield is up. Adjustable side vents also allow the rider to direct warm air on or away from their legs, depending on outside temperature.

After adjusting mine outward my shins did feel less hot on the way home today. Then again the air temp was about 5 degrees cooler as well. I think that tomorrow I'll have one in and one out and see how much difference I feel.

 

[DrBunsen]

Yep, definitely like it better with the side panels out. I had the right one back in and felt more hot airflow over my shins.

Now I'm wondering how I can make those newly exposed screw-holes look better.

Yea, I was thinking the same thing. They should have at least supplied a rubber plug for em.

I have been riding with my panels out for several weeks now. The temp indicator said 109 yesterday on the way home. I definetly don't get the hot air blast on my lower legs like I was before.

 

[c2insa]

I tested the out position yesterday. 107 degrees in slow moving traffic. It was much cooler than the in position. and chicks dig it too.....

So where'd you get the picture of my mother-in-law?

Man, that is classic. :clapping:

:blink: What I think is the scary part is mother's are a good indicator of what the daughter will look and act like in a couple of decades?

STC 10,

Does your pup always look that smart?

:blink:

 

[Fencer]

OK FRED, I concure with you assessment. I usually ride with gloves, but i took em off yest. While riding with the panel out it did decrease air flow on the body, but it was hotter manifold ait that was decreased. I did not feel any air comming from between the bike frame and open fairing. It also helped with protection in the rain.

Summer = open panel

I think it made a big difference. It takes about 1 minute to move them either way, probably the best way is to try both ways and stick with what works for you. All you need is a screwdriver.

Riding in Alaska, we need all the heat we can get. I have removed all of the '06's "air-management foam," with the exception of the heat shield under the tank. I removed the plastic side pieces that helped hold the shield on with those nutty rivets Yamaha is so addicted to, giving me more warm air at my upper legs.

I have placed some of the removed foam in the vents near the headlights. On my CalSci windscreen I have plugged the vent hole with a blue tinted piece of thin plexi-glass (from Home Depot) that surprisingly looks good. It is weird, but I didn't find any significant change in the airflow pattern (buffeting, etc) after plugging the vent on this screen. Just less air on my neck.

I have found more heat on my legs with the side vents in the inward position.

Happy Riding

Um..ok...here we go. Many of my friends female parents, I call mom. It's an indian thing....don't expect anyone to understand that. :blink:

Well, I have my flow in the "out" position and I could definitely feel hot air blowing on both my shins and ankles yesterday. It was about 100 degrees when I took my ride. I'll give another run either later today or tomorrow with them in the "in" position.

BTW, how much of a gap should there be when in the "out" position? I loosened the screws and pulled them out lightly and tightened the screws. It didn't seem like much of a difference between the frame and the fairing. Maybe I don't have mine in the full open out position... :confusedsmiley:

The adjustment is not variable. They are either in or out. There are 2 sets of holes for the fasteners to go in. Remove the screws completely, being careful not to loose them, pull out on the top of the fairing while looking through the empty screw holes :dribble: until you see the outward position (about 1 inch). Reinstall the screws in the outboard holes. You should be able to see the holes for the inboard position i n the gap created by moving them. Sounds confusing but all will become clear if you try it.

I tried them outboard in 100+ degree heat. About all I noticed was four fugly holes in the fairing now. Maybe my left foot is a little cooler, but too subjective a test.
