    On the GS the water ingress into the snorkel is bad & there was also a recall on the GS OEM paper filter due to collapse & failure to seal

    Using the Unifilter & the US made K&P Stainless Steel washable oil filter I have no reliance on BMW consumables for servicing

    Look at the air flow graph ( middle on the right)

    Why do people insist on mounting the spring in the Unifilter anyway ? It makes it more prone to damage fitting it/taking it out for cleaning the filter.
    The Twin Air filter is also of the inverted sock type and does not use a spring. It doesn't need one as it (and the Uni one) is not prone to collapse.

    If they've (UNI) put in the R&D and concluded the spring is the best solution....I'm not saying (general) you're arrogant if you don't use it, but the performance numbers of the UNI filter might not be applicable anymore.

    I should add that my experience comes from the GS, so I tend to picture my own air box, filter and snorkel when thinking of air filters and not particularly familiar with the x airbox.

    I use a K&N myself. Bought it in 2005. Had some dust on the inside of the air box a few times, so don't think it's a very good filter, but it up'd the torque of the engine....well...that might've been the Staintune exhaust too as I did both those mods at the same time before doing a DYNO run. Using the foam block in it now and hope that helps a little.
    The UNI filters were just too expensive for me taking shipping into account even when @Aquatic had stocked a small fortune worth.

    That seems like a good choice in my book.

    eBay. If you search for X Challenge parts you're not going to get many returns. The set I bought were listed for a 2016 F800/F800R. The stalks are slightly shorter than the originals but otherwise identical. Paid $45 for the pair.

    You did your entire trip on the original air shock? I missed that on your ride report.

    The choice was easy.. replace the shock or spend an extra month traveling in south america. Plus I've never ridden anything else so I don't have anything to compare it to.

    I'm now in the market for a used replacement. Hyperpro or other. But would also like to get this gauge working again in the short term.

    It looks like there should be an o-ring in there.

    I would recommend anything but hyperpro with this point is I have blown mine up three times in the last 9 months of travelling. however I do think it would be an improvement over the air shock

    They are the same pump as a MTB shock pump. So if you cant fix it replacement is easy.

    Yes missing an o-ring, here should be a small one in there that the gauge side presses against when you tighten it.

    Just wanted to point out to the group, I recognize your name... Andrew is one of the original group posters on the XCountry thread, going back to when he purchased that bike in August 2008 !!! Too bad the pictures in your old posts are dead now... Andrew I remember reading your posts of the skid plate you were making, the first one I saw anyone make, (long before Scheffelmeier gave us choices). And your videos of jumping the bike over little berms really got me going until I ended up buying mine in March 2010 (but it took me 2 shocks later until I found one that could actually be jumped!).

    Anyhow, I respect your history and wisdom on the X and welcome back. Mine is totaled and still sitting under a tarp on a trailer in my yard, but like I've said I will still keep my website up, though I will not be owning the X again, more than likely. So everybody respect your X "elders", and Andrew is one of them!
