    Wow! I took a look at the Guglatech and it’s pretty cool that essentially acts like a paper filter but it can be washed.

    For whatever it's worth we used the powerparts foam filters at Merzouga in addition to some prefilter socks on the inlets to the airbox backed with expanded metal to keep the prefilter from sucking into the inlet. We plugged the prefilters daily and replaced the filters daily as they were always packed, and did not have any issues with dust getting past the filter. It did look like those filters would be a little more of a pain to clean. Highly recommend rigging up some kind of prefilter sock since that seemed to make a really significant difference in how much made it into the airbox, as those trumpets like to suck the dirty air coming off the back tire. We did grease the hell out of the seal surface around the filter element, which may have made a big difference based on earlier pictures. The more the filter loads up, the more it's going to want to suck dirty air around that seal face.

    Very cool. I run Outerwears on my RAM intake. Didn't realize I could buy it bulk. I could have been sewing my own for my bikes and trucks all this time. Definitely want to fashion an inner mesh framework so the pre-filter doesn't just get sucked in.

    No, I have never seen them for sale. The ones we used were just sections of prefilter material with a zip tie around the snorkel to keep it in place.

    I’m going to use these in combination with the PP filter. Saw a video awhile back from some guy in Australia that tried them and showed how they helped filter the dust on his 790.

    What’s the deal with guglatech? It looks like a k&n style filter.

    Here’s the video on the pre filters

    One of the first things I changed after my 790r purchase was install the guglatech air filter and their fuel pump sock. I don't really ride much in dusty conditions so have only had a look at the filter once in 2,000 miles and it was fine and nothing noticeable in the intakes. Yes it seems similar to K&N and that filter gets a bad rap sometimes. Not sure the differences between the guglatech and K&N. Might be in the details of the materials used.

    What sort of grease does one use on the inside edge of the filters?

    I use waterproof grease. The stuff I have at home now is bel ray, but I’m sure there are lots of options. It’s messy but it will seal the edges of the filter against the plastic housing. Old school method of making sure no dust can get around the filter.

    I haven’t had the 790 in dusty situations yet but have done lots of filter changes on my 640 enduro and there is never any dirt that gets through the grease seal.

    I got my filter from guglatech before I got the bike installed the day i got it ,after riding 150 miles.
    a month ago I did the MA BDR most of the ride I rode behind a 701 which kicked up walls of dust add to that the dust I created the bike and me were full of dust
    got home took out the filter it was filthy but the airbox was clean no dust.
    I use Rock Oil Factory Foam Eco Foam Air Filter Fluid
    wash the filter in warm water and and gentle soap,let it dry reapply spray and i was done.
    the rest of the bike needed much attention(i did the best i could ;))

    Perfect, I have some on the shelf. Leftover from greasing the thrust bearings when I redid my 500's suspension. Thanks!

    How was the MA BDR? Looks like it’s a fairly easy ride. Looking forward to the NEBDR, planning on riding it this summer. Should be a good mix of easy to expert terrain.

    A few moderate parts but fairly easy
    Except the bridge that was knocked down to be rebuilt.. We had to improvise a bit and make our own trail betwen some trees down to the stream and over the other bank.
    Planing on doing the NE in summer as well but North to South
