    Thinking about adding a 390 to the stable, my 690 is fun most of the time but I want a lighter bush basher. I have my eye on a 2010 with 2200 km, is there anything to look out for specific to the year model?
    I have been researching these little gems and I think I need to own one.
    After toying with the idea of getting a 300 2t, my gut feeling tells me to stay with 4 strokes.
    I plan on keeping the 690, possibly motardizing it. Its such a hoon rig

    Two easily fixed issues with the slant engine 'Bergs that I am sure are detailed somewhere in this thread.

    First, if it has not been replaced, the fuel pump in the '10 is suspect. They get hot, lock up and then after they cool they will work again, but will crap out for good soon after the initial lock up episode. Later pumps have more clearance/better made and do not do this. CA Cycle sells a pump for the 'Bergs and Huskys for around $125 that works. Have had a CA Cycle pump in my '10 FE450 for about 80 hours now, no issues and I have ridden in the gnarly stuff where it gets good and warm under the tank .

    The other thing to address is fuel filtration. The stock paper filter in the tank is not fine enough to protect the injector. KTM/Berg later came out with pathetically small filters that go up by the injector that clog.

    The answer is to spend $4 on a Walbro manufactured canister fuel filter available at Autozone. It is 10 micron, never clogs and kicks ass! Put the filter in place of the quick disconnect and never worry again. So simple, and probably a mod that is worth doing on your 690. KTM seems to have it&#8217;s head up it&#8217;s ass when it comes to fuel filtration.

    Aside from these foibles, the Berg is a solid bike. Engine is a cool design with a single oil supply (1.5L). The whirly KTM sourced metal bits have proven to be reliable. I love the nature of the slant engine's power delivery and feel it imparts to the bike. The slant engine 'Bergs are passé now, but have good qualities that will serve me well for many years to come.

    That autozone link isn't working on Tapatalk for me. Could you tell me what the part number is?

    Here is my new to me `10 FE390, 170 hours, 5k kms:

    I've made an "aggressive map dongle", added FMF 4.1 can, the bike runs very nice. It is a funny bike, at first it feels like there is no great low end torque (coming from an XR426!), but it is very tractable down low and revs up in an instant. Love it, the engine, EFI, suspension, great package.

    I just did a valve check, was horrified for pulling the tank, but everything fits nice, no worries.

    Nice bike Diravi!


    Could someone tell me what the wiring colors are for the front and rear turn signals using the KTM cev switch?

    I'm horrible at reading wire schemetics. I don't understand how to read them. I guess that's why I'm an accountant.

    These wires are all behind my headlight. I have one plug out back under my seat with a KTM connector. It has Brown, purple and black. Since there is two connectors up front with Brown/Black and Purple/Black I'm assuming this is the turn signals. Now I'm trying to figure out what a black yellow wire is with a butt connector and which connector is for the horn.

    Here is my sorry redneck setup, complete with coathanger wire and old radiator hose for cushioning. :evil

    The filter goes in place of the quick connect. When pulling the tank, I leave the filter on the line, that way the sensitive injector side is never exposed to the dusty dirty cruel world.

    DJH sells the manual cam chain tensioner. I put these on all my dirt bikes. Don't even really know of KTM has an issue with this, but so many brands do have CCT issues that it is a reflex action at this point. Not much to go wrong with a screw and locknut. Set it properly, keep clean oil in it and forget about it :)

    Bonus 'Berg photo. The weep hole on the water pump faces forward. Over time fine grit can get in and work on the seal. "DaleEO" over on the Unofficial Husaberg Forum came up with this mod - adding a nipple and hose to the weep hole. I did mine in 'Berg blue! Got the tiny tubing at an RC supply store.

    I agree the manual CCT is the cats pajamas. My cam chain must be worn more than yours because it is adjusted correctly..

    Ok guys, what fan kit are you installing to help with over heating? I did some tougher single track today and over heating was definately an issue.

    Added the KTM fan kit and still was not entirely happy as the KTM thermo switch does not kick in until it is around 220F coming off the head. (I have a Trail Tech Temp gauge). I think this is a hangover from the older RFS bikes, which have little stator output and drain the battery if the fan runs too much.

    I think the KTM switch is 100/105C. I am running a 90/95C switch meant for a 1984 BMW 318i car has my fan coming on around 206F, again measured coming off the head. The earlier activation of the fan creates more "reserve" before it gets stinky hot, and keeps the temp below 215 pretty much no matter how tortuous the trail, and I ride some rocky gnarly stuff here in CO in the thin air. If you are reasonably nimble, you can unscrew the KTM switch and screw in the car one with almost no coolant loss. The Napa part number is ATM 1435033, here is a link to the switch I am using.

    http://www.napaonline.com/Catalog/C.../Coolant-Fan-Switch/_/R-ATM1435033_0257596936

    Also spliced in a manual fan switch but I honestly don't use it much since adding the car thermo switch. These bikes have 211 watts of stator output and can run the fan continuously, so draining the battery is not an issue. The only downside to all this cooling goodness is my right thigh can get roasted medium rare at times, particularly if I am sitting. This encourages me to stand up more as I ride, something I should be doing anyway :lol3

    The 'Berg wiring harness has pigtails for the KTM fan kit. It is all plug and play.

    Updated my post #5015 above with labels. At least what I think the wiring is for. Just looking for someone to help and confirm.

    The previous owner told me all 'Bergs come with the map switch. Is this true and the handlebar mount is just for convenience? Or did he pull one over on me?

    The yel/blk is engine kill just like the other one in the pic, the Berg has two. I have one connected to the CEV kill button and the other to a Sicass key switch.

    As for the Map switch, it is not factory installed, his dealer may have given it to him for free. The plug for it is there from the factory but the actual switch has to be added.

    how about a color coded one?

    yes, the purple/black & brown/black wires are turn signals, those are the plugs going to the TS lights themselves coming out of your turn signal switch on the bars.

    your turn signal relay should have a purple/black & brown/black wire going to it from the light switch on the bars.

    the horn plug should be purple/yellow & grey according to the diagram. can't tell from the pic.

    edit:

    (i may be color blind, and/or your model year may be different colors....this is for '09)

    H2 - LF turn signal
    H8 - parking lamp
    H9 - headlight
    H7 - HI beam indicator light
    H4 - TS indicator light
    H3 - RF turn signal
    B8 - map switch (IIRC)
    P1 - dashboard

    K3 - TS flasher
    S2 - front brakelight switch
    S4 - turn signal switch (CEV switch half on bars)
    S5 - headlight/kill/horn switch (CEV switch half on bars)
    H10 - horn
    S6 - rear brakelight switch

    X200 - Tail/Brake light wire harness plug under the seat (white 4 PIN plug, only 3 wires)
    X400 - Turn signal wire harness plug under the seat (white 3 PIN plug, 3 wires)

    H6 - LR turn signal
    H11 - license plate light
    H12 - brake light
    H5 - RR turn signal

    This is great. Thank you very much.

    Additional wiring question.

    Sicass racing told me the Husaberg comes with the Horn wiring. They said the wiring is tied back in the harness under the frame.

    I removed the tank but still don't see it. Next step is to remove the radiators so I can see what's in between.

    Is the horn wiring there? Or am I. On a witch hunt. Is it a set of spade connectors?
