CRF450X now with LoudMouth filter system

Great purchase. Easy install and the filter keeps clean for awhile and is easy to remove and clean. Has a MUCH better deal then OEM. One of those upgrades that are well worth the money. Can't go wrong with this system.

Impressive USA build quality.

I was thoroughly impressed with the build quality of this intake. Main plate is milled from a thick piece of aluminum and looks really trick. All of the welds are very clean. This is clearly a high end, high quality part. The filter seal is full contact and nothing will seep by. Also, I can hear the intake when I pop the throttle. The extra air flow seems to make throttle response a little snappier and the intake "hiss" is awesome.

Haven't gotten time to put the new one on, but liked the one I put on my older CRF250R that it was a no brainer. Great product that makes a terrible job a bit easier.

Excellent to look at

Definitely catches the eye easy to put in and could hear it sucking air when just idling

Small Modification Insane Power Boost

Bought this air intake system for my YZ125 and the power increase was insane. My bike has so much more power through the entire powerband than it did before. Plus this system seals 100% of dirt out of your engine and makes filter changes quick and easy. Installation was also a breeze. Buy this product you won't regret it.

Better than stock

The stock Husky/KTM air boot/cage design is total garbage.

After 1 single day at the track I would have dirt past my filter and down the air boot almost every time.

The Loudmouth system fixes that problem by eliminating that junk plastic/rubber strap that holds the already poorly designed air filter/cage assembly in.

Only problem I had is the kit they send you for a Husqvarna is the same kit they use on a KTM. The airbox on a Husqvarna is a different shape than the KTM...... The part still fits you just need to trim the airbox so the loudmouth adapter sits flat. By doing this you now have about a 1" opening on the front side of your air box just under the plastic latch for the side panel.

I'm happy to have a filter system that will actually seal. Just wish they would make a Husqvarna specific part that doesn't require me to hack my airbox up.

A: On it's own the power increase is insignificant. However, with the increase of air intake, a jet kit or power commander, plus a full system exhaust is going to give you the most power gains,

I would like to install on my son's Yz 850, how easy it to install and how much power gain will he get on flat dusty track in Botswana? Would we have to increase or decrease the sprocket sizes front or back, any suggestions.

A: Installation is simple depending on prior MODS. This will help throttle response. Cleaning and regular maintenance is a Snap!!
Q: Does this kit get rid of the back fire screen?
Over 3 years ago
Just wondering what happens to the back fire screen with this kit, as I'm not comfortable removing the screen for a tiny improvement in performance, at the cost of a fire in the air box. Thanks in advance!

A: Yes. The Loud Mouth is a very simple system. Intake (flange on housing) and clamp-on style filter. It eliminates the thumb screw, cage and OEM filter receiver. The filters manufactured by Twin Air and No Toil are flame retardant. According to these companies, a non-petroleum-based filter oil is recommended. Avoid petroleum-based solvents, gasoline, mineral spirits etc..
Q: I have a 2007 KX450F. Would I need to adjust my jetting?

Would I need to adjust the jetting on my bike? Could I correct any discrepancies with the air/fuel screw? Or It should I just leave it alone.

A: Loudmouth claims that you will not need to re jet after installing the kit. You should not have to rejet.

A: The Loud Mouth makes as much performance as $2000 in bolt-ons. It's proven, patent pending technology and it will keep dirt from entering your engine. Filter maintenance so easy that you'll save 20 minutes to an hour per weekend on filter changes. As a rider, the air filter is the number one thing you work with and the most important part on your bike. You might as well be happy when you pull your seat off after a long day of riding.
