Anybody have and/or use them. What is your opinion?

I've used one on a CRF450. Super easy to change. Great seal, never have to worry about any air leakage. No stupid wing nuts to play with. I'd say go for it.

Do you or would you still use one? Did it require any different tuning or jetting? The opening just seems a lot smaller than factory restricting air.

The CRF450 didn't have a problem. Fuel injection.

I have a KTM 150 right now, and I would love one for the convenience factor. Like you said tho, it does look fairly restricting on the KTM. That I can't answer for you. I just don't know enough about jetting to know if that much of a restriction would make a difference. That picture looks about half the size of a factory filter.

I agree about the size thing, which is my concern. This has me leaning more towards the twin air or this moose kit.

Any links to those? I wouldn't mind taking a look.

To be honest I think I like the twin air better. The moose will keep the filter from moving a little better, but the twin air has a lot better sealing area than the moose.

I emailed them and asked them about the narrower opening and this is their response:
The Loud Mouth Intake gathers air from low flowing areas and concentrates it as a higher velocity flow entering the intake tract. It's based off of Bernoulli's principle of fluid dynamics. When constricted, the velocity of a fluid (Air) increases. Obviously there are limits, but that's what we have engineers for.

You should not have to touch jetting/mapping and installation is quite simple. Everybody that gets it on their KTM's claim big increases in Bottom end performance as well as gains all over the RPM range.

Still don't know which way I want to go.

Well that's all good info! Thanks!

On a side note, for oil changes, do you use the left or the right side drain plug? The right one, on my 150, is a smaller bolt and feels like it is stripping out the case, but the left (shifter side) seems like it would just make a huge mess trying to drain oil out of it.

I had no idea what you were talking about till I looked at the manual. There isn't a shifter side plug on the 250's. The only one we have is right by the rear brake. And looking at the pictures in the manual the 250's is a lot bigger. It almost reads like you are suppose to remove both of your plugs to drain the oil. Not sure why.

The smaller opening theory is correct assuming the intake is too large to begin with. How does one know?

I've seen some guys run smaller carbs for more low end. Only like 1-2mm smaller.

They , on every bike make more power then a stock style system with the screen removed. As for protection against dirt... Bar none the best.

And I'm about to take the plunge and install on my new KTM 250SX.

Let me know how it goes for you. I am highly interested.

I use the one on the shifter side. Doesnt really make much of a mess, just do it while the bike is on a triangle. Drain it out and wipe the frame and youre good to go.

The 10 mm one on the right side is to check ur oil level

Sweet thanks! I'll give that a try next time I do it. I really don't like the one on the right side.

Braders - The oil check level is an 8mm I believe, and it's up higher than the one I'm talking about. There is a lower plug on the brake side that drains the cases. That's the one I was having problems with.

This is the response I got from loudmouth when I emailed them about the smaller size and jetting. With that said it still has me leary. I personally like the twin air the best for sealing area and it seems to have a nice dish out to keep it in place without pins. I'm don't know though. I think you should all put a different set up on your bike and get back to me on who likes what! hahaha

Edit. Damn it. I meant to put this in diggers thread.
