Fairing Vents

[ScrapeApe]

Due to what seems like is mass confusion, I wanted to share this. After reading numerous posts, I finally decided to mess with my fairing vents. They have been in the closed (in) position since it was purchased. I opened them yesterday and rode 30 miles of freeway in 97' heat. What I found was that my lower legs were much warmer with the vents OPEN (out). Today, they will be closed and remain that way until NOV-DEC. Just thought I would add this to the pile of words concerning fairing vents.

I didn't know we had movable fairing vents. What fairing vents? Pics maybe?

Hasn't anyone contacted Yamaha to get their take on these "cowlings" work?

The outboard position will slightly reduce airflow, but it also will direct the hot air that comes out of the forward opening in the fairing off your lower legs some.

Reach down with your hand and feel the air temp coming off the sides of the fairing near your lower legs, and I think you will then understand the intended purpose of them. There is a thin layer (about 2 inches or so) of hot air that flows along the outer surface of the fairing panels. This is what gets deflected off your legs when they are out.

There is no vent that they open around the frame to allow airflow when in the outboard position. All they are is deflectors. Look closely at the design of them and I think the puzzle pieces will fall into place.

It must depend on how you position your legs while you ride. Like Fred, I too have found my lower legs to be cooler with the vents open (out). I typically keep my legs tucked in close to the bike.

I have tried them in and out on the same ride and IN is cooler, NO question about it.

I have tried to call Mr. Yamaha but he's on vacation and won't be back in the office for a couple of more weeks..

Go figure. I have tried them in and out on the same ride and OUT is cooler.

Try this test. Put one in, and one out, and then go for a ride and pay attention to how much heat you feel on your lower legs.

Did that. Even swapped with which side was open vs. closed. I think what happens is that with the vents out, it creates a bigger hole in the wind, reducing airflow around the rider, allowing engine heat to saturate. It is defintely cooler with deflectors closed at freeway speeds. The design appears to deflect the air coming out of the slit in the fairing away from the rider, but I think this is a case of reverse engineering. Maybe it's time for another poll and a general concensus on this matter?

Well, I think the main purpose of the moveable panels is to adjust the amount of heat on your lower legs, not your whole body. I suspect you aren't paying enough attention to how the hot air on your lower legs has changed.

But hey, I could be wrong, have been before.

Well, this sounds like a job for a Yamaha "Product Specialist". Since I have been in contact with one in the past, I volunteer to try to contact him. Unfortunately, you have to battle a barage of front line Customer Service reps before they let you talk to a "Product Specialist". It could take a while ... (days or weeks). I'll see what I can do.

Well, in the final analysis, I guess all that really matters is where YOU want to ride with them. Some may want them out in hot weather and some may want them in.

All that really matters is that you are comfortable, so experment with them and then do whatever works best for you.

There, how is that for a politically correct response?

Stay tuned tomorrow for another exciting episode of, "As the Stomach Turns"!

For what its worth, I am just totally confused as to whether it is better in or out. I seem to get more "fresh" air when they are in, unless I hug the tank. When they are out, I get more air passing thru, but the air is warm.

This will be an interesting test when the temps get into the 30s.

I think you hit the nail on the head. The Yamaha literature which talks about the "Air Management System" says that the adjustable side vents allow the rider to direct warm air on or away from their legs. It says nothing about directing cool air with these things, only warm air. So, the only question is where the warm air is directed when the vents are open as opposed to where the warm air is directed when the vents are closed. This is what I will be asking Yamaha, if I ever get through.

I think the vent discussion has ventured right in to never ending and pointless discussion. No offense, all, just nobody seems to have a consensus. Try both and see which YOU like.

OK, if nobody cares how it's supposed to work, then I won't bother contacting Yamaha.

Well, Yamaha is suppose to be at WFO in Reno so maybe they could fill us in there. Well I guess I vented enough.... see you in Reno God willing. PM. <>< :lol:
