I' m not a racer but I'll disagree with it (dirty filters). Maybe slightly dirty won't matter, but when they really get plugged up - doing the job
you put them on for - mileage dives.

The problem is not with the filter being dirty, it's with the element not being fine enough to filter out the dust and it getting into the cylinders.
That's why Ken was recommending the pre-filter.

Getting Gassed
We can look forward to this, and related, threads going on for a LONG, LONG time. There are NO short-term fixes available for the fuel price problem
despite what ANY political hack might say. We're going to have to get used to this. The only "action" we'll see will be the new administration
blaming the previous one for the problem when, in reality, both factions have rejected the other's attempts to prevent the situation.
Most of us will grouse, complain and simply pay the price while moderating our lifestyle in some respect when said price becomes more than an
irritation.
I suppose one Upside is that most severly effected will be the Lower classes who can't afford to acquire alternate and more fuel-efficient vehicles,
but also can't afford the fuel cost for their gas-guzzlers. Since most of them aren't going to work, that could be a plus for the economy.
Another problem, should we have a severe Winter, will be those who can't afford the Heating Oil. Perhaps they can move to Florida.
In the meantime, WE can look for ways to fuel our Trucks and SUVs while we complain.

In my case the element is fine enough to get the dust - it gets so plugged that it is choking the engine. Knock the dirt out and it the buggy runs OK
again. The larger the area of filter media, the longer it will last without plugging up in heavy dust.
Pre filters work great at reducing the total dirt getting to the filter. I used to sell them to garbage landfill operators to put on the tractors to
extend the life of the filter elements. These elements have a indicator that shows when to change by measuring the amount of air restriction caused
by the filter. Without a pre-filter, if a element doesn't get plugged up in severe dust, it isn't doing it's job and is allowing dirt into the
cylinders.
I am now running the canister type with internal blades to swirl the intake air, similar to some pre-cleaners, to throw much of the dirt out before
the air hits the element.

On a race bike we'd oil a womans stocking and put it over the filter and feed the end out an opening so at the first pit we could pull the stocking
off and out. The dust for a bike would be in the early part of the race where most of the passing (and getting passed) takes place.

I would add to the string on dirty air filters.....mileage isn't the only thing that is a concern. If the fuel mixture becomes more rich than normal,
this extra little bit of fuel vapor can certainly help in cleaning off the cylinder walls which, in turn, lead to premture wear on those parts and
also the ringsand valve buildup. I'll bet a dollar to a donut, if you had two similar engines and ran one with a dirty filter and the other one was
maintained, cleaned and replaced regularly, the the latter engine would still be running well after the former developed some serious issues
internally.
Just a thought.....
