    Thanks Boatman- Would you say those carb settings apply to sea level to 3000ft?

    BTW I removed the pre-filter, put the snorkel back on and hard start problem solved. Seems the combination of the pre-filter opening being smaller than the snorkel & and oiled foam restricts enough airflow to requiring jetting to compensate.

    For now, I'm not going to re-jet, and I think I will leave the snorkel on, and simply ziptie some UNI universal foam over the snorkel opening when I get in super dusty conditions-

    btw I have 2 new prefilters in the packaging I'd sell $20ea

    Seems to me that replacing the paper filter and upgrading to the full UNI set up - and running with out the top of the filter box on would produce best performance. When you look at all the hardware the air has to pass by in the airbox before it gets to the paper filter- sure seems that airflow would be less than optimal.

    Will either of the two versions require remapping of the FI system on the 990? Or can I just install and go?

    On a standard bike with no other modifications you should not need to remap the bike when using the off road version. On the road version you may need to adjust the settings slightly as the air flow will be improved over the standard filter.

    Going down on the mains was actually the change I made when I installed the pre filter.



    I'm at around 1200' and been sea level to probably well over 3000'.

    Ok afta much chatter we have our filter and prefilter.

    I cut some small channels in the UNI for the airbox front clearance where the cables come through as it was making the opening considerably smaller with a big bow in the base.

    Also took a few comparo photos of the snorkel v prefilter, looking at the two there would be very little in it if at all in theory restriction wise.

    My reasoning in the UNI is 200mm shorter in the intake length thus less drag, the UNI inlet would be pretty close to that of the top of the snorkel which is the bottle neck of the system.

    The fit and finish of the MW-R is good and an easy install.

    We change the engine oil at 5000km and wash the filters at the same time so will continue to do that with this.

    Will do fuel economy tests again now, at sea level we were doing 46 - 48 MPG and mountains up and done 38 - 42 so we have good comparos.

    If we find it restrictive we will open the two side doors up and glue some of the same or similar foam in place as precleaners.

    Anyway, here are the pics.

    You didn't need to cut those notches.... the base fits perfect if you turn it around. Yeah it looks the same but it's not. No big deal though.

    I turned it around 180 degrees and no better fit either way so that us why I notched them out.

    I checked the depth of the grove both sides and neither would work.

    Interesting,,,

    I wonder if Uni Australia makes them differently? Pics of mine below....

    Installed correctly...

    Also thought it was interesting the label says the filter fits 950 and 990 bikes.

    FYI , don't do what I did , I had a filter sock over the UNI and just cleaned that and ignored the foam since it looked clean .

    It was full of dirt when I got around to cleaning it after my 950 started smoking from sucking oil up the crankcase vent ...oops !:eek1

    Hi We have fitted our final sample panel filter for the 990 Adventure & Super Duke to a couple of test bikes. We will have them available from June 1st. Any question please ask.

    Sorry I have had issues posting photos from Photobucket today so here is a link to our Facebook page where you will find some pics. https://www.facebook.com/UnifilterAustralia

    thanks for the heads up, interested to why you developed the Panel filters as well as the figure 8 filter.
    What are the Pro's and Cons of each ??

    In regards to why having two filter designs. It wasn't our intensions. Originally we just planed on having the figure 8 design. But after designing that filter we were able to use the manufacturing process to develope the panel filter.

    As you can see the original paper filter is not like any other panel filter with the intake trumpets coming through and sealing the filter. This makes it hard to re-produce the panel using foam as there is no strength in foam. Our new state of the art CNC foam cutting machine allows us to cut and shape the foam foam in a way we can successfully mould the foam into the urethane seal. We have been able to scollop hollow the foam block out to increase the surface area of the filter and allow the foam to be dropped into a mould to attach the urethane seal for the trumpets and the air box sealing edge.

    Both filters have their benefits, The figure 8 design is two stage with the 2nd stage been able to be removed for easy cleaning. It also has a bigger surface area providing a longer service time.

    The panel is a simple straight replacement panel filter providing better filtration over the standard paper filter. No crank case breather filters required.

    Both are completely servicable.

    We are also looking for a 1190 Adventure to design a filter for. If in Australia and in Sydney or the NSW Central Coast will would like to hear from you.

    Cheers

    Hi we have finished the figure 8 filter for the 950 and will testing over the next few weeks. Should have it available from June 1st too. We will make a panel filter for this too. It will be available towards the end of June.

    Griz, didn't you like the other style foam filter?

    Do you know which of the two is more restrictive
    using stock airbox with snorkel?

    I did. It's good. The panel style seems more simple though. I like the idea of a foam panel style.
