Still no dust fix

I posted this in another thread but it's OT there so i thought I'd get it off my chest in its own topic.

We--manufacturers, dealers, hobbiests--are all running around like chickens with our heads cut off jumping on unproven "solutions" to the dust issue. I've suspected for a long time that nobody really knows what the problem is. As reports come in of people still getting dust on their TB after spending hours or hundreds of $$, I'm more convinced everyone is just guessing. I'm becoming more convinced every day that the Rzr is capable of sucking dust right through a high-quality air filter. I don't know if the problem is intake restriction leading to a vacuum in the canister, the fact that many of us ride our Rzrs WOT far more than we would any other machine we've owned, tiny leaks around the filter, or who-knows-what but it's clear that dust is getting by the filter and coating the canister outlet tube, rubber boot and TB throttle plate.
All filters have an efficiency rating. Let's say it traps 99.99% of particles 5 microns and larger. That means .01% of every CFM your engine draws is dirty. ANY change that results in cleaner air to the filter will result in less dirt going into your cylinders. Most of the "fixes" we've seen are simply attempts to feed the filter better air but they do not fix the base problem--just make it more manageable. I'm not criticizing the work that has been done to try to improve the situation. Something HAS to be done--even if it's wrong. My gripe is with the claims that this housing or that tube, etc. is THE fix.

At this point in time I don't think even Polaris knows what the problem is or if they do, it possibly can't be fixed cheaply so they keep mum on the subject.

Just the opinion of someone who's been watching very closely for the past 12 months.

I hope Polaris surprises the hell out of me and has made a major change in the '09 Rzr. We'll just have to wait & see.

I agree with dragonfireracing 100%, the problem is that the dust is getting sucked in through the intake tube clamps, whether you use grease, rtv gasket sealer, or anything else it doesnt matter, because the airbox itself is mounted to the frame and is not able to flex with the engine, therefore those intake tube connections will never actually be 100% sealed anytime the engine is flexing.

How is it going to get by the rtv gasket sealer??? Guys have used that and silicone...both are flexible and should seal it up better then any stock clamp alone. Unless the filter is clogged...there's not that much air flow to pull that much dirt through those connections if sealed up?

you all want to talk about the air filter not flexing since its mounted to the frame well go open the hood on a few cars most are mounted to the fenderwells that are not flexing the tube flexes so that isnt the issue i agree i to think the dirt is getting throught the filter also remeber any engine will also have a buildup on the throtoll body look at any car or truck pull and look and you will see build up so are all eng defective? not a negitive person here just pointing out some facts their is almost no way for a massed produced thing to be perfect no mater how bad we want it to be if it was they would cost 100,000 each and still would have problems

I agree with ya Johnnycat I am using the kms kit and have had 0 dirt get by that is visable to the naked eye. Never really had any on the stcok set up. I ride in very dusty areas ie the wagon wheel just ask any body who has been here. But running a offroad vehicle no matter who makes it requires more maitance than the truck you hauled it there with. I clean my filter after everyride. Change the oil and oil filter after every other ride. grease after everyride if I submerge. and always clean it up so I can inspect for damage of anykind.

change the oil and filter after every ride 25 dollars a ride for the oil and new filter 25 thats 50 bucks everytime u ride or get A NEW motor

Damn where you buy oil and filter at.

The difference is that a car is not driven in dust 95% of the time like a rzr is, which is made to be an off road machine, a car is not made to be an offroad machine. I dont want to argue with anyone but we all have our own opinions and I'm not even saying that anyone is right or wrong, and we may never find out the true answer. But I see that a lot of people are saying that the dust is coming right through the filter, then why are so many people switching to an aftermarket filter setup, the aftermarket filters almost always have more and better airflow than the stock one, so aftermarket will make the problem worse!!! People are still getting dust with several aftermarket filters installed, so if dust is coming in through the filter then, that means almost all air filters out there are complete junk!! I just dont agree with that. I think the dust is getting sucked in somewhere else, but like I said, thats just my opinion and we all have our own.

Your opinion counts, very good points. most after market filters and all off road filters require you to oil them. I guess this is to help stop some of the dust from getting through

My airfilter was CLEAN, very little dust on it or in my airbox, BUT the boot going from the airbox to the t-body was dirty on the outside of the boot only at the throttle body end, pulled the air filter off and the intake tube was clean inside until it got to the throttle body and then there was a small amount of dirt/dust sitting at the bottom of the throttle body, I really think it has a lot to do with such a short hose going from the air box to the t-body and with it being mounted to the frame it moves slightly different than the engine and I am sure it is not alot but enough to pull a slight amount of air through the hose clamps and BAM dirt at the throttle body...... Just my opinion from what I have seen on my machine so far with only 103 miles and 8.4 hours on it. I am going to try the Dragon Fire Intake Well see if I am wasting my time and money, I hope not

how is the air box connected to the throttle body?

the airbox is technically not "connected' to the throttle body but the intake tube from the airbox to the throttle body is the "connecting link" between the two. I agree with rzrcrzr completely, filter was clean, airbox clean, but still dirt in throttle body, the problem is not with the filter or airbox itself, it is the piss poor design of the intake routing from the airbox to the throttle body.

sounds like the hose is the problem then bad connections?lousy hose itself?

Mine is still at the dealer. When the dust problem was found I also found it to be using oil. The dealer is now rebuilding my top end and replacing my air filter. I had only 29 hours on her! I feel that the problems are causing more than just repair costs. If you look up the wholesale on a 2008 RZR at Kelley Blue Book (New Car Prices, Used Car Prices, Blue Book Value, Car Reviews - Official Kelley Blue Book Site) my brand new 2008 is worth $6,600! Besides for the recall crap my RZR is in mint condition. This really hurts the pocketbook, it is like just stealing 4k of my money when it is not our fault they have a bad design.

Ignore the blue book, it's true value is what people are prepared to pay for it - since it's sold out everywhere and there is a waiting list it's entirely reasonable to charge list price or even more since you are offering instant availability.

The downside is that I imagine used RZRs are given a wide bearth because of the whole dust thing. If anything, higher mileage ones are probably more attractive since their lengthier lifespans indicate they run fine.
