    Haven’t decided which way I’m going to run it. All depends on where it hits the Canadian border in Maine, but I’m guessing it’s going to be by Ft Kent. Assuming that’s the case I’ll run N to S as well.

    We need 'somebody to design a pre-filter assembly to replace the lid that eliminates the snorkles without restricting flow...:hmmmmm

    B Bolton has suggested that the 2 drain grommets in the bottom of the airbox should be replaced with blanking grommets if riding in very dusty conditions... They've seen some dust sucked back thru.
    Maybe the blokes at Triple Clamp Moto are already looking at the prefilter idea?

    Yeah the oem has the filter trapped in a cage, near impossible to clean properly.
    https://www.uniflow.com.au/contents/en-us/d369_KTMADV.html scroll down a bit to get to the new filter assembly, spare foams and now, snorkel prefilters.

    I was under the impression that all AU bikes either had the oem filter swapped out at delivery or unfilters shipped out following for early deliveries (like mine - and no charge)...

    Paper filter removed on pre-delivery and replaced with foam Uni filter (Not-Oz version).
    Lots of dust got through filter and past seal (1000km service done day before ride) - KTM Aus had Air box and throttle bodies removed and cleaned, and supplied/fitted Oz Uni filter.
    Gunna keep an eye on the valve clearances and oil consumption KTM Aus will look after any associated issues.

    The Oz Uni filter is a much better fit around the Air box groove than the other Unifilter.

    I pulled the new filter and greased fuck out of the seal (although it had been greased) for piece of mind.

    Uni-not Oz? This is confusing. Anyone got a link for the good one?

    New to this world - is this only am issue for off road riding? If I'm exclusively on road are the disposable filters fine, or should I still be looking into oiled and greased?
    Thanks

    Paper filters better than foam for onroad, no question about it.

    I run equipment as a side hustle and it's DUSTY so here's my take on filter media. These machines are pricey and have pretty sophisticated filtration systems to keep the engines alive. But in the end it's a dual paper filter setup inner/outer primary/secondary. They filter well, probably better than anything but are slightly restrictive. I'm a fan of paper filters with outerwears material to pre-filter.

    If I go on a trip, what good is an oil bath filter that will be more or less un-cleanable on the trail without bringing a lot of crap along with to service it and spend time every day to do so? With a paper filter it can be bonded to the gasket creating a leak free joint and when they get full of crap you can simply beat the crap out of them pretty easily. It won't be clean and flow like a new filter again but it will flow just find for off road use.Who needs 95HP, 89 should do fine?

    For reference, I beat the crap out of my primary filters probably 4 or 5 times before replacement and they hold a lot of crap, at 80 bucks a pop I get what I feel comfortable with out of them. Probably a full measuring cup or more of dust/dirt comes out each time if I run it till it tells me it's clogged. the secondary filter shows no signs of material getting through either, they have always been clean when I replace them.

    It's hard to beat the convenience and reliability of a paper filter IMO and I'm not concerned with the possible 2 or 3 HP a better flowing filter may provide if it ends up being harmful to the engine.
