Dry Country Air Filter

Postby Doc » Tue Jun 04, 2013 4:26 am

Anyone try the Raceway Ural Dry Country Air Filter (PN10263)

http://racewayservicespaa.com/ural-accessories-page-1.html

What is the overall consensus on the best air filter modification set up for these rigs?

Doc, do some searching on "airbox." There is a great product in development right now from WindMill. There is also a review for the Raceway Pods. From my experience with the Modtop airbox, and a better system then Raceways, IMHO, simply because of the "box" or shroud (This thread will divert now that I said that... :lol: ), tuning can be a pain when using pods. A combined source of air for both carbs, a plenum, is required for the bike to run well. I combined my two pods and got better results.

I am well experienced with heavy rain, sleet and road spray causing the Ural filter to clog up, which is why I switched to the Modtop box years ago. I am now testing FrogzSkin on the intake of the stock box. This product was designed for Snowmobiles. The skin keeps water, dirt, snow out, but allows air to pass. For the vast majority of Ural owners who don't report water ingestion issues, or have experienced it only a couple of times, this may be all they need, again, IMHO.

+1 on the need for a plenum...there are better options than that "dry country" set up (you are right Derek...we'll be labeled haters). Several of us have worked on our own air boxes that far out perform the stock box and as Berger said, windmill has a fantastic option that is being tested now by several steeds and is less expensive and by all measures a far superior system. It's always good to ask...good luck!

With the risk of starting an all out airbox war (or at the least an airbox thread), what does "far out perform the stock box" translate to? I've enjoyed reading all the threads and watching the development of the various airboxes.....however.....

Are you getting measurably better gas mileage? Are you getting measurably better torque/power? :pot: :D

While I cannot attest to more torque or mileage (not caring about the later personally) because I never tracked them, the piece of mind of not having to worry about water ingestion or filter clogging due to sand, dust snow on trips, was the main reason I switched. The issue with Pods, of any design, is the difficulty in tuning them.

Spoken as a true professional! I can fully understand and relate to the "physical" aspects of a different airbox design. Thanks Derek. :cheers:

Yes,
Measurably improved fuel mileage, measurably improved real world Torque/power, increased resistance to the elements, and improved serviceability.

I have been fooling with this for years, pods are simple and inexpensive, one of the first things I tried. They are too exposed to the elements, and have a narrow power band, didn't like them at all.

OK I am extremely anal about numbers...... When I ask "measurably", I meant real world numbers...not just how it feels.
What was the measured gas mileage with the stock vs the new? What was the measured stock torque/hp vs new?

Darrell,
if you follow my posts on my 3 air boxes you see:
leftka 1 - 15% increase in fuel econoy over stock, and big jump in performance from stock...no dyno tests but corraboration from others that did the same type of box. Virtually water proof and 2 minutes to service the high flow k&N filter
Leftka 2 the plastc windmill with precleaner- less fuel economy than leftka 1, still 7% better fuel economy than stock. Huge jump in low end midrange torque over stock, gave back some top end vs leftka 1. still a 2minute service job with just a screwdriver to loosen a hose clamp.
Leftka 3- hit over 30 mpg with this box...stock box was lucky to get 23mpg. right sized intake and large prefilter volume created an excellent compromise between leftka 1 and 2 delivering excellent fuel economy and srtong torque through the entire power band.
Windmill has similar documented results with his windmill and we are seeing that the MK III delivers improved performance, an OE look and a 2 minute service time.
Go back read the posts follow the numbers, "far out perform" may be an understatement...

Mr. Cobs MK-III installation thread shows how " numbers" can be obtained in the real world. viewtopic.php?f=11&t=28442

I keep track of my fuel mileage on every fill up...even have a fuelly display in signature to show the tracking...don't know of anyone that dyno's thier rig, but i know Cob and windmill have a specific track that they test on, as do i. we all track things like top speed, top sustainable speed, speed in what gear at a same point on a hill or point on the track. windmill even has a gauge on his throttle to measure 1/8, 1/4, 1/2 and 3/4 throttle to measure the speed at those points. all in all think its accurate to say that the results and improvements are very well documented.

What numbers do you have before and after you drilled your slides?
Changed your Needles?
put in Herzog timing Gears?
changed your mufflers?
Just askin'... :D

I knew that was going to bite me in the posterior! :lol:

1. Drilled my slides because it was free and did make a "marked" improvement on throttle response (notice I didn't say measurable!) :D
2. The needles I was anal about numbers. Wanted to see the difference between the older stock needles vs the newer stock needles. There is a "measurable"
difference....two M3 washer difference.
3. I intstalled Herzog timing gears because I am third owner of rig and not sure how the first owner took care of it. Plus I did it for the experience and love of wrenching.
There is a "marked" improvement on noise level.
4. I changed my mufflers for the sole purpose of trying to keep them on the rig when I off road. I lost my left pontoon twice at Moab and vowed to find a different
solution. The Harley Sportster mufflers are short and sit tight to the frame. Plus, I got this set for $30. :D
