    You're ordering a $60 air conditioning filter from us... right? :evil Don't worry, we know how to handle customs... (Canadian shipments priority mail usually take 3 to 5 days USPS)

    Anybody know if you'd still have to take that Safari tank off in order to clean/change-out the Rottie on a SE? I'm guessing yes, but didn't see it anywhere for sure. If you don't, man that would rock.:clap

    Sooooo tired of removing that tank every time the dust gets close to the beast ....:puke1

    Uli-

    You CAN access the filter w/o removing the tank... one of the reasons I went for it!!! Sorry I don't have a pic.

    I am running an oiled pre filter. It's easy to reach in, grab a dirty one, and put another on. If you want to remove the entire filter assembly, you'll have to reach in to get the front fastener. The trickiest part is on re-assembly making absolutely sure you have the lip seated correctly on the left side and the fasteners in line for a good seal. It's worth double checking when you do it, for obvious reasons.

    Ease of service alone makes this setup worth it. The added oomph... I'll take that too! :D

    Personally, I'd pretty much count on having to remove the tank to get filter off/on CLEANLY with the OEM tank or any other aftermarket tank. There just isn't enough room to easily get your hand/arm between the tank and the filter to get to the forward fastener.... and even if you could, I'm pretty darn sure that there isn't enough room to get the filter over the velocity stacks with the tank in place. On top of that, you would be dealing with a DIRTY filter over the top of the open CLEAN side....

    Thanks guys for the opinions. Hmmmmmm .... Uli has pretty damn big hands. They are great for moving kegs of IPA:slurp; not so great for working in confined places. (You should hear my German cursing when I'm trying to stick the carbs back into that blasted black box. "Where's the hidden camera?")
    Riding off-blacktop mostly in the dusty states -- think John Wayne or Sergio Leone here :jose -- cleaning the filter is a daily chore. (How often can you take a Safari Tank off and put it back on before it totally falls apart anyway?)
    I can spray my hands with filter oil to lube 'em up to get in those tiny recesses. Lube me up, I'm going in ...

    The foam prefilter and/or the 'filterskin' is a workable solution that would allow you to maintain a mostly clean primary filter while out in the dusty wildness... there is enough room to easily remove/replace both of these type of filters that go over the primary filter, even with Hulk Hands Hans (Uli)

    Been using that for a few years but just can't replace the skins with a Safari Tank on it. I can pull a skin off if I tie a bit of string to it.
    I was contemplating replacing the entire gooble-di-gop (German technical description for air filtration system) with something I can clean by the campfire at night.
    Keep searching ...

    When I say "prefilter" and "filterskin", I am talking specifically about the add on options to the CPR filter, not a "prefilter" for the OEM airbox.

    We have something coming very soon (sorry, only for Adventure owners) that will make filter changes insanely fast and easy. We are very excited about this one and will have them at the KTM Rally. Stay tuned. :evil

    (And yes, this on is patent pending)

    Here is some tinkering for you.

    Go with 14.1 up to 20% and 4,500RPM. This is your closed loop MPG area. Some engines will idle smoother at 13.1-13.5. If yours idles better at that then leave it there. After 20% TPS you want to add fuel evenly until you get to 12.8. Kinda like this,
    [​IMG]
    but we are starting at 14.1. Ride with that map for a couple hundred miles. Pull the map then save it to your laptop. Make another one and set everything to 12.2. More fuel like this on the bottom will increase torque a little. Ride with this map for a few hundred miles. If you can't tell a difference, put the other map in. If you find some areas that you like the second map better (richer map) then add fuel to the first map in that area and try it. Anything you change in the closed loop area "<20%TPS" will effect MPG.
    Report back on your findings for others to try.

    I'll post up pics to show you what to set the LCD to that will show you (what we feel) the best info. We use the dual dial with the 5 squares below.

    • Dial left: Front AFR
    • Dial right: Rear AFR
    • block 1 (from left to right): fuel adjustment front
    • block 2: fuel adjustment rear
    • block 3: gear (I will show you what wire to tap to do this)
    • block 4: RPM
    • block 5: throttle position
    This will allow you to see pertinent information for tuning as in at what RPM and TP are the cylinders putting out AFR wise. The only thing we would like to add is temp but if your at 13.0 plus or minus your good.

    Got it Tahoeacr. I will set it up and try it over the next couple of days.

    CPR, you're gonna force me to do it...:D

    You'd be wrong. There is plenty of room to get both the pre-filter off and the main filter in and out. Once it covered in dust the "wetness" of the oil is mostly gone so it is not that messy. Nothing a single paper towel can't handle. You have to remove the glove box and trim (obviously and then there is a TON of room in there. As mentioned earlier...you just have to make triple sure the filter is cliped over the lip on the left side.

    We are talking about two different things here..... Yes, of course it will work with a ADV, either with OEM or AfterMarket Tanks, as you describe...... With the SE/SM it is as I have described. :freaky

    Well, I held a response till now until I had a chance to verify my thoughts.

    I am at home today being a good Bro-in-law fixing motor mounts on a 2003 Civic. YeeHa. Wish I was working on the beast instead.

    I am waiting on parts @ O'Reilly's so I fiddled.

    FWIW, this is meant as no disrespect or jab... just personal experience. I have a ton of respect for H2W, purchase & own his products, and have reached out numerous times to him for tech support with great results. I also get the concerns of removing a dirty filter/filter rim over open throttle bodies... so I appreciate his words of CAUTION! This is info for the collective, esp. those on the fence regarding benefits & downfalls of mods.

    The Steed:
    2007 950SE: sickeningly not very stock any more
    [​IMG]

    Mods affecting airbox area:
    Safari Valdeze tank
    Desmog (of course w/ this filter setup)
    CPR filter, xrings, and updated baseplate
    Oiled Filter skins (I misspoke earlier & called them a prefilter. The foam prefilter for the CPR setup is for you ADV folk. Skins for us SE folk)
    Rejet
    CJ Designs trimmed intake horns
    I even have my fuzeblock mounted in front of the filter assembly, on the splash guard behind the ECU. It works great... I keep my underseat storage for spare parts, fuel line & fittings, tool kit, etc.

    This took all of 4 minutes taking pics. No cleaning done, just removal & replacement. All done w/ my big gorilla hands & forearms!

    I'd say it's doable. I havent yet "trashed" the filter in the muck and dirt, but I love it so far. It's done a great job of filtering so far, but I'll keep watching carefully.

    I'm sure if this would be attempted w/ stock height intake horns, it would be more difficult, but stock height wont work w/ the domed filter.

    As has been said multiple times, double-triple-quadruple check the left (clutch side) bottomw lip of the filter to make sure it captures the baseplate correctly. I use a headlamp to light the crucial areas to make sure it's in place. Then use your God-given thumbs and fingers to gently squeeze the filter and baseplate tab together. Use no tools! It should not be hard. On my first fitment, I had to help it in place more. Now that it's been on the bike a while, I falls right in place.

    What say you?
