    Tried it on a Husky TR650. It wasn't worth it in the end as the ECU will learn to counteract it on Lambda values.

    Clutch Plates
    So with making an effort to address known issues on these bikes I ordered the appropriate replacement clutch cover for my new to me 10,000 mile bike. (Clutch seems to drag very slightly and pretty much can adjust it out of there with the cable adjuster on the perch.)
    I was figuring to replace the friction plates while in there for a clean base line but BMW wants to sell the clutch as a package with steels and springs for $270.
    Is there a preferred go to source for the friction plates on these bikes? I am a big fan of quality and longevity and dont really abuse a clutch.

    Thanks

    Get the EBC friction plates. Unless the steel plates are warped, just reuse them.

    Thinking on clutch friction plates...

    My X hase just under 30K miles and I have been considering replacing the plates, just updated the clutch case cover and both operation and drag are fine, however when I did the case cover I couldn't find a Spec on the thicknes of the pack or plates to check them, visual inspection they seemed fine, so am not sure if I really need to replace or not.

    Im not sure either but figured while I am in there it may be peace of mind. I hate doing things twice.

    That was my thinking but couldn't get plates local and didn't look up the EBC plates before hand as I should have.

    Just found a set on Ebay for the 650 Dakar. From what I read these should fit......Nothing EBC was coming up under our Unicorns!

    Correct. Use the Dakar parts.

    We are talking about two different devices.

    The one you describe is an IAT shifter which it does learn around and negate. You're right, a waste of money.
    The one I mention actually changes the voltage that the ECU sees from the O2 sensor so there's nothing for it to relearn. It simply uses the existing AFR tables in the fuel map as though the O2 sensor is telling the ECU the mixture is lean.
    Thanks!

    You've probably already seen the quoted post below but, it sounds like we'd just need a different cable for use on the xchallenge.

    I ran an AF-XIED on my F800GS and it worked great. I'd be interested to see how it performs on the xchallenge.

    Hi Matt, Thank you for your reply.
    A couple guys I know use them on their BMSK controlled bikes and, like you, find them to be a great addition to the bike.
    I'll call BB now and see what they have. I'll report back when I get some useful info.
    Thank you

    Hi all,my troubles with the water pump continue...
    To recap, I've done the pump seals and shaft at 11000 km,after noticing gradual water loss from the overflow tank.

    Now,at 23000 km,i changed the oil (no water in it) and started the bike after a 6 month hibernation.

    This time, however, there was a visible stream of coolant from the weep hole!!

    Worth noting is that it starts to leak immediately when started and almost no leakage when stopped.

    Any ideas where to look now? Is there any reported case of the radiator cap NOT venting excess pressure into the overflow??

    I'm thinking like that since also there's no pressing of water out through the overflow reservoir and into the drain tube (had it full to the brim especially to check that!)

    Thanks!

    I remember seeing an alternative radiator cap for our bikes on here. Don't know what page though :lol3

    The seal on mine seems to be on its way out too but I'll keep topping up the coolant for now. It's not much on mine.

    You are right. The TR was running so lean it often died in mid traffic !
    Both out X bikes are running perfectly though so I'll leave it at that. I am going to fit a bigger injector though to see what that brings.

    Very interesting about the bigger injector. Please keep me posted.
    I'm not looking for more power, just more smooth and cool running.
    I wasn't able to get ahold of Beemer Boneyard today so I'll try on Monday. It looks like they do have a harness that will fit but I must be sure before I'll order one.

    Some Bosch injector information is here. Wayne C did a bunch of work on the GS911 diagnostic tool and was working on the F650gs, G650x and Husky Terra. You can find the injector recommended for the X for around $120. The other way to cheat the system is to use a higher fuel pressure, but that is a harder nut to crack since the pump and regulator are stuffed in the tank on the X.

    I posted this in the X front suspension thread also and thought maybe a wider audience would wander through here:

    Great thread! Thank you all for your information and willingness to share.

    Let's say that cost is no object and I want the best handling, smoothest riding set up that exists for dual sporting. Not much single track, more high desert and pine forests. I weigh about 105kg with gear.
    What would be the most ideal set up? (I want to ride the damn thing, not spend my time tinkering and making a Frankenstein mishmash of parts.)
