I have one for my 250r, and I really like the idea, but it is a pain in the a$$ to jet accordingly. I rather get the outerwears airbox cover instead.
I ordered a EHS airbox lid today.
Will post a picture of it installed once I get it. He told me would be about 1 week before he could get to mine. He has alot of back orders to fill.

Ok thanks joe hope the guy was right when he said to jet it with no cover and will be right. You scaring me now
Trust me when I say HELL NO, the jetting won't be the same!! With my 450R, with airbox lid cut (hrc airbox lid), I have to run one jet size smaller than if I were running no lid at all! When you put that cover over the hole in the airbox, it really cuts down the airflow. I know when i tried the lid setup on my 250R, I had to jet down 2 full sizes in order for it to not run too rich! I would setup your bike for jetting with a cut airbox lid (i'm running 185) if I were to run no lid at all I would go to 188 or 190! Feel how your bike feels with the cut lid!!! Then install the outerwear setup. If you feel like you have lost some power, then I would jet down 1 size.Ok thanks joe hope the guy was right when he said to jet it with no cover and will be right.

don't know what its worth but dirt wheels said they didn't need to rejet on their yammy when they tested it
i like the looks of the k&N lid does anyone have it
The EHS w/ outerwears will be 100% better than the K&N IMO because the outerwears are a whole lot easier to clean!
why does anyone ever mention what they read in Dirt wheels cause everytime someone does they get a flaming pile of crap shot at there faces. Is dirt wheels really that unreliable, does no one ever trust that they say any truth? Everytime they saysomething good about a product it's cause they want ad money? everytime they say something bad it's cause that products competitor spends more money in ads?

I had one of those lids! and I already metioned that it cut down my airflow ALOT!! I'm not saying the idea is not a good one, but just will not perform like an open airbox or even a cut airbox. The jetting will be different! the fact that dirtwheel wrote and article and said that it peforms like an open airbox, just proves to me once again that they are an unreliable source, Desert 450r has a point in saying that they don't want to piss off potential advertisers. There is a reason why dirtwheels test certain products and not others and that is $$$$ I'm sure some one will have to pay to get their product evaluated in dirtwheels..i mean there is no better advertising!! the lid is a nice alternative to running a an airbox lid, but it is not an alternative to running an open airbox lid ...IMOwhy does anyone ever mention what they read in Dirt wheels cause everytime someone does they get a flaming pile of crap shot at there faces.

all dirt wheels does is lie....all they want is money...they dont care about the truth...I think we should boycott them.

I ran one of these lids on a suzuki z400 with the same jetting as no lid at all and had no problems at all. I couldn't notice a difference. I have one for my r now and just got my bike back today so I haven't tried it yet. As far as not flowing as well as a cut lid, The hole for the ehs lid is alot bigger than the hrc hole so it should flow better. Why do you think it wouldn't?
hmmm maybe someone should wire an intake fan under the ehs material
B)
*shrug* just kidding but heck it might work

Hmm i think if we velcroed a pre-filter on top (like a filter pad or filter paper) with a fan that would pulled enough it would work. Probably have to change the pad/paper pretty often. but a 4micron pad is cheap enough, and i think you could follow your regular filter cleanings. Do you think there is room in the airbox for good sized fan?
I got a Matsupoopa AC Fan thats about 4.5inx4.5in and 1.5in thick.
i dont know if this would be enough but, is pushes it's an industrial
fan the cool off larger breaker boxes, Cool large electric motors
(with a filter pad over them) I understand what you saying about the
motor might just start pulling in more air then the fan can push. I still think we can find a fan powerfull enough it just might take some fitting mods.. About how much air and at what force does the motor pull in air at what rpm is the max?
5psi = alot of friggin air
5psi is WAY WAY to much for a 4wheeler. My 87 RX7 has a 5psi turbo
the normally aspirated has about 20+ less Hp, 5psi on a 4wheeler would
blow up.
(I know you werent implying this but i read on some forum where a guy
wanted to turbo charge his 450r w/ 5psi And saying he wouldnt need an
intercooler because it was only 5psi.) (YIKES)

I think we'd need a completly new box, alluminum frame, walls made out of the ehs material (i dont know what it is and i dont wanna say the wrong thing) put a fan in the from what the fan becomes out pulled by the engine it can start pulling from the other walls, Surley if it's out pulling a decently powered fan, the resistance that the material gives wont be signifgant at that point.
*shrug* These smaller engines seem to be more responsive to anything
compared to a car ( It would be easier to tell a difference between stock air filter
versus a sparks for example compared to a car) IMO

IMO, I don't think it is a volume concern as the air will get in there if the motor sucks hard enough ... But I anticipate a velocity drop across the material ... It has to ... Then it would affect throttle response, hence torque ...
Testing and feedback will tell us more than speculation though ... Let us know how you feel after some use !

Ok, I see your point, buts whats the difference if the outerwear covers your airbox or your filter. It still has to go through it.
So If I understand what you are trying to say. You feel if you run an outerwears whether over the filter or covering the lid you will need different jetting. I find this alittle hard to believe. On my z I ran a K&N with an outerwears and a EHS cover, a K&n with no lid and a outerwears and a stock filter with no lid. I never changed the jetting between these 3 different ways and I never had any problems, it didn't feel any different riding it. Although there may be a difference it may not be noticable to make any difference. When I sugested to a tech at several local dealers that running an outerwears on a filter would change the jetting they laughed at me. I not saying you're wrong I'm just suggesting it may not make that big of a difference.......Maybe we should get ahold of dyno jet or GT thunder(they like to dyno different combinations for the heck of it) to see if they have tested or could.
