    No worries vintage, google found this bit of CEV info:

    Headlight switch: 50311070100
    Adapter bracket: 13011070060
    Flasher switch: 50311029000

    Thanks vintage , for the water pump link. Very helpfull.
    Outer seal had a bunch of sand behind it from the weep hole.
    I think I will replace the back seal also.

    it's o' beer thirtay! :freaky

    wrapped the harness in an old tube
    cleaned the injector & TB
    added the CanAm fuel filter
    removed O2 sensor
    added KTM headlight (soon to be LED...)
    removed the old kill switch & added the CEV switch

    i'm loving working on the Berg. all those comments i read about them being "difficult" and "awkward" to work on were totally misleading. :deal every wire connector was in place, the proper length and ready to connect up, plug & play.

    i can't wait to get this thing in the dirt!

    next up will be the low fuel sender, brake lights, UHD tube in the rear, remove the Tubliss front (soon for sale), install some black hoops, cush hub and a safari tank.

    Thanks for posting the shots. It looks very bright. So you wired it to 12v, when it came stock with a 8.4v battery pack? That would explain the extra brightness. I hope the regulator is multi-V and handles it no issues.
    That's a lot of lumens for the $$.

    I am thinking about converting my 390 to a light-rally set up (safari front tank, & 70 degree tank for a total of 5 gallons) and a nav tower setup. If I had a 450 I wouldn't think about a big bore kit. But since I have a 390, I am wondering if anyone knows of a big bore kit to bring it up to 450 or close. I do have a 690 with a full rally set up that I used at the recently held at the 1st Baja rally, but I thought a 450 would be more better suited.

    Thinking the same thing. What's the downside of keeping the 390?
    Granted that the goal was not podium finishes?

    Another rally prepper here. I was thinking of just going Safari rear tank...not sure it will be enough for the next Baja Rally though. My buddy Angelo said the fuel stops were pretty close together...in your opinion how would the 570 be? I think Bajadad ran his 570?

    purpose: reduce low throttle flame outs and hard starting, lean condition at idle

    i thought I'd do a quick how-to on adjusting your TPS sensor. i've read some write-ups about measuring the voltage at the TPS, even some using a 5v power supply to measure the TPS signal.

    i dont agree that using an external power supply to adjust the TPS provides any practical benefit other than confirming the TPS sensor is working. it's inaccurate because it doesn't measure what the ECU is actually seeing on the bike, through the bike harness. poor grounds or corroded terminals will cause high resistance in the TPS circuit and will cause the ECU to see a lower voltage than what is measured at the TPS itself. the only way to know what the ECU is actually seeing is to measure the TPS voltage at the ECU with the signal returning through all the connectors and grounds on the bike. plus, it's easy and you dont have to build anything!

    to measure the signal return at the ECU, i used two metal sewing needles, i passed each needle through the connector at the ECU plug, without disconnecting the plug. i didn't pierce any wires so there is no future corrosion issue. simply pass the needles past the insulator and into the connector at the ECU.

    the signal wire from the TPS is a yellow wire, number #5 at the ECU plug. the ground wire from to the TPS (and other sensors) is a black wire, pin number #24. both easily found on the ECU.

    whole procedure should take about 5mins. :d

    1. remove (or just loosen) the plastic cover over the ECU and slide the ECU out to the side where you can get to the connector.
    2. slide your needles into the back of the connector on pin #5 (yellow) and pin#24 (black), DONT LET THEM TOUCH! there is only one solid yellow and one solid black wire on the ECU so you can't get the wrong wires.
    3. measure resistance to ground (negative battery terminal) on the black wire in ohms to make sure you have a good low resistance connection, if it's fairly high then you'll want to clean your ground connections for the harness and at the battery.
    4. connect your multimeter to the needles, red on the yellow wire (pin #5) and black on the black wire (pin #24).
    5. jumper pins #5 & 6 on the diagnostic port (black/white and brown wires). this will power on the bike, you will hear the fuel pump prime and the headlight will turn on while these pins are jumpered. i used a high tech paperclip for this.
    6. your multimeter will read out the voltage across the two pins.
    7. adjust the TPS idle voltage by loosening the torx screw and rotating the sensor. counter-clockwise to increase the TPS voltage, clockwise to reduce TPS voltage. shoot for .64v with the throttle closed (idle position). it takes a little messing to get it perfect. when satisfied, tighten the torx screw.
    8. hold the throttle wide open (engine should be OFF) and check max output voltage signal from the TPS.
    9. disconnect the wires, remove the pins, remove paperclip from diagnostic connector and start the bike up and let it idle for 5mins to calibrate. not sure if this is actually necessary, but it's all over the boards...

    now from my research on the web, i found very little about measuring the TPS voltage on a Berg, but many KTM articles. in the KTM articles they mention .64 for the proper TPS return voltage at idle, i do not know exactly what Husaberg recommends this setting to be.

    when i measured my bike it was lean measuring .58v:

    adjusted TPS to .64v (note fancy blue paperclip my wife gave me):

    hope that's useful to someone out there! :freaky

    They were those colours from '83

    through to '93

    After that they went to variations of blue/yellow with much less white, until in '06 or '07 they oddly used Honda colours... which they used from 1903 until 1982.

    Yes fuel range was not an issue at the recent Baja Rally. Bajadad had an excellent setup on his 570. He raced the NORRA 1000 earlier this year on his 690 (similar set up as mine) and was very happy with it. However he was glad to be on he 570 for this one and I felt the same. My concern is the power of the 390 in technical terrain ( mostly dunes, sand washes ) with the extra fuel load and the nav tower set up.

    True, but I still think the 390 doesnt have enough power down low to go over dunes and long stretch of sand washes.

    Your 390 would do perfectly fine

    I have been wanting a Berg for awhile now but I don't see many around here. I think I may have found a low mileage 570.

    Now that KTM is dropping Husaburg do you see any problems getting parts down the road? I know a lot of parts are from KTM's but what percentage are unique?

    I plan on keeping the bike for a long time and am not to worried about resale value. I know that because they are no longer make that will effect selling value. I'm hoping that will help me out now.

    Thanks

    i'm in the same boat, bought mine and i dont plan on letting it go EVER! :lol3

    i think enough of the engine is KTM that there wont be trouble finding parts down the road.

    All the wear items (brakes, sprockets, bearings) are standard KTM parts.
    The engine is standard KTM except for the cases which are slightly different.
    A few things like the seat and air filter are specific to the Berg, but are still readily available.

    The only issue in the future might be the availability of plastics if you want to keep the bike fresh looking.
