    >>I know this setup will not work on an SM, that is my issue. Could be the same issue with the SE.

    Don't the SE have the same tnaks as the ADV?

    >>smalled or slanted fiter for the one side that touches the tank on the SM

    There's no stock part that would fit and K&N do make specials but the price is $80 per filter, which adds up quickly! I'm still kicking around ways around it but realize that I did choose these filters because they fit best!

    It seems like a lot of 950SM guys are interested in the kits! It figures that the version of the bike that the kit does not fit well may be the most popular one.

    Even though K&N has nothing stock that is suitable and the custom filter program is pricey I continued to look for ways to fill that space in the market. At the instigation of a list member who purchased the Full Monty system yet wanted to find a way to keep his Rottweiler air filter system I started digging again.

    Initially I though I'd have to bite the bullet and fork over the NRE charges needed to develop a custom filter shape for this application. I found a couple of companies that do this and emailed inquiries. At the same time the customer had asked CPR if it was possible to adapt their system for the FCRs. A few emails later we realized two nicely dovetailing facts:

    1. I did not want to invest in a foam filter design that may not be a good seller.

    2. CPR Fabrications was focused on the FI market and didn't have much interest in doing a kit for FCR carbs.

    After a bit of discussions with Chris Parker at CPR we came to the conclusion that a CPR filter on a set of Cosentino Engineering velocity stacks would be a great product for the FCR carbs. Since CPR was not really interested in the FCR market they agreed to sell me filter elements and cages that I would design FCR bellmouths and a lower filter mount around.

    CPR would benefit by selling more filters and I'd benefit by not having to do the R&D needed to get an optimized filter. By partnering with CPR I also get the benefit of having KTM Orange parts instead of whatever the OEM produces! The Rottweiler filter element is not an off-the-shelf part, they worked with the manufacturer to tweak the foam's properties for this specific application. Its one of those rare situations where instead of two companies trying to undercut each other we decided instead to work together. CPR did a lot of R&D on their setup and were the first on the scene with this type of filter system. Copying their design would not be something that's cool to do. I've done a bunch of R&D on the FCR setup and seem to be the only alternative to the non-optimized Sudco parts. Them glomming my efforts would have left a bad taste in my mouth. So instead of 2 companies fighting over a niche market we'll collaborate instead.

    The end result is that I am working on a revised FCR kit that will utilize the Rottweiler optimized filter system and revised versions of my velocity stacks that will fit on ALL the 950 models. As of now pricing is uncertain but it should not be more than the K&N kit, which will still be available. Performance gains for both kits should be similar so it will come down to filter preference, or if you have a SM, its the foam version.

    I hope to have a kit ready before spring and although having another project on my plate sort of sucks, if all the interest that has been shown comes through it will be worth it.

    I'll keep posting updates to this list (and likely on Gregor's 950 refresh thread too) so keep posted for updates.

    This is great news Chris!!! I have been watching this thread waiting for the day to be able to get the FCR’S with your stacks on my SM. I just happened to read over most of this thread tonight and then saw your post, great timing ;)

    Not to be greedy, but will a choke solution be ready as well?

    Thanks...Kent

    Very interesting! :ear

    I imagine the total filter surface area would be greater with the CPR filter vs the K&N ?

    I still have my stacks on the shelf and will be saving them for the day you get that Rottweiler adapter done! Chris@CPR is a smart fella and I can see how the two of you would want to go at this conversation from the same side of the table. Did he mention his special chambered mufflers? They may be interesting for some of your other pursuits.

    All the best for your efforts!

    07 KTM 950SE 39mm fcr's , single pull cables only & 1/5 quick action throttle.

    I just installed the TPS bracket

    is this the right settings ?


    TPS reading set at -0.55
    [​IMG]



    TPS @ WOT reads at -5.21 ? ? ?
    [​IMG]


    Or are the leads in the wrong holes ? black in the bottom red in the middle should be ?

    update:
    swapped the meter leads as above - black in the bottom red in the middle

    had a play with the settings again now have it set at

    0.56 closed
    3.66 WOT

    so that's in the 0.5 closed & 3.6 WOT

    PM'd him a couple of weeks ago. He did not know if they would fit the SMR, but said they do not fit the SM very well.

    Well there are two more of us SE owners up here in Saskatchewan that have elevated heart rates now and are curious about the full package fit up on our 950 SE. Can't wait to se it. :clap

    I've learnt two things recently;

    1 - When not balanced for cruise revs, they give big vibes to the bike. Though it feels powerful, it is unpleasant. It takes really fine adjustment to make a difference. When balanced, it's very smooth and strong.

    2 - Going for a quick swim, even though I turned the engine off before we went under, had filter skins on and had the bike up in seconds, water is going to go down those two big drains.

    The hole is behind

    That's thigh deep, I cross rutted and couldn't keep it up

    [​IMG]

    There's a dam down there. Front vales were open. I was on my own. Used the centre stand to tip the bike upside down to get the water out the carbs and exhausts.

    [​IMG]

    Once I'd cranked the water out with plugs out and dried as much as I could, I tried starting it. My Lithium battery fused itself after about 20 seconds and left me stranded. Nothing for it but to call a freind and get on with drying my clothes

    Aaaaan we're outta here.

    Oil filter was swollen but oil wasn't milky, two oil changes later and my beast was back.

    One of the few times, I missed my airbox

    Hmmm.

    I've dumped my SE in water. Not very deep. Silly, silly thing it was, went to dab, but caught my pants on the footpeg. But I got it up again, and I didnt even bother looking - I knew there was no way water could have gotten past the airbox, let alone the air filter...

    Its the one concern I have in ditching the airbox... I guess I will just steer clear of water :lol3

    Shame kamanya, not much luck, dumping in water AND having your Li battery crap out on you.

    I got nuthin but heavy breathing to add... and the note that my SM still needs someone less busy to swap motors from the seizure salad in the chassis, for the runner in the tub on the garage floor.
