    Did you clean and set the overthruster volumn control valve to 2.5 turns out? :ear

    No? :eek1

    Yer' doomed. :grim

    In other words... adequate power.

    It's how Rolls Royce, when asked, would describe power output. A euphemism for "plenty 'O power... don't ask again you twit".

    I'm having trouble getting hold of some copper tube to make the burping tool. Can I use just the clear plastic hose pushed through the stopper instead? Does anyone know if there will tears if I try this??

    Colin,

    On an '03 and later bike, with the large hole in the top of the breastpipe, just sticking the KTM provided hose in the hole to add the 600 mL will work fine....

    You can use what ever is practical and logical for you. The "burp tool" is just something I made up in an effort to eliminate any mess, rather than anything manditory.
    The mess that is usually made without a burp tool is fairly minor... if your quick about shuting the bike off at the first sign of oil. :evil

    Cheers, thanks fellahs.

    I appreciate where you are coming from regards the burp tool; just didn't want to ignore having the solid tube if there was a good reason for it.

    btw thanks for all the tech how-to's. It's easier to learn from someone else's experience! My dealer did the 5000km service and removed the radiators, replaced the coolant etc because he didn't know any better - which of course, I had to pay for.

    This 10,000km service will be my first on the KTM. Should be simple with your documents.

    Woo hoo!... nothing like paying for someone else's education is there. :wink: Hell, you may have even bought him some new tools too! :lol3

    Thanks to everyone involved in making this tech thread. Did my first oil change today and made a mess, but it wasn't too bad. I'll be making a special burp tool for my '02 before the next time.

    First off, Creepers instructions were great... but I got so caught up in following them and building a burp tool, that I over looked the fact that the oil that a friend picked up for me at the dealer was 10w 40 non synthetic until I had it in the bike.

    I'm leaving on a trip tomorrow and it took so long for me to change that I was hoping that you guys will tell me it's no sweat change it to synthetic when you get back...

    It's my first oil change on a 2006 with 800km on it and I put usually put synthetic in all my vehicles... should I dump it before I go?

    Na... go for your ride, change it when you get back. It's not that big a deal one time around.

    Ya, I guess I'm being a little too uptight about it.

    Thanks

    Up until a few years ago, KTM didn't even recommend synthetic oil. As long as what you put in isn't Pep Boys paraffin base sludge but rather something decent... it'll be fine.

    Questions:
    Why is this not a good idea on the 03 and later bikes? I see they have a different sized bolt/hole but for the life of me can't understand why that would matter.

    Also, is it critical to tighten the bolt and then shut off the engine (in that order)?

    Danke

    Meat my friend... the first paragraphs I wrote involved tearing you a new asshole.
    Then I remembered something that I try very hard to remember and as often forget... something I need to remind myself of so often that the last paragraph is actually that reminder.
    And the first few paragraphs are a toned down version of the original asshole tearing. :wink:

    It's a fine idea on '03 to present... as Chris has already indicated.
    What makes it extra fine for '02 and earlier is that the smaller size of the filler bolt makes the more complicated "burp hose" method somewhat less effective.
    Allowing the oil to simply bleed past the filler bolt is a quicker, simpler and only slightly more messy method... if your timing is good.

    When I wrote that DIY guide, I said right up front that nothing is chiseled in stone, that there may be a better or different way that works for you.

    I learn new and better ways to do things every day, and although the method may not be new and better for some... it's a perfectly viable alternative to the more finicky, neat freak burp hose thing that I came up with a few years ago as my first alternative to the book method.
    If you'll recall at the time, there was no guide anywhere other than the owners manual and there were a buttload of people spinning out about changing their oil... so much so that they were paying a dealer to do it.
    My original intent was to provide a simple, clean blow by blow methodology for the novice oil changer.

    Some people can only do, or even think about one thing at a time, so for those folks, would you rather stop the oil from spewing all over your bike first, or shut off the engine first... which does stop the pump, but does nothing for the oil level that's an inch above your filler bolt by now?

    I've lost track of how many times I've tried to explain how the LC4 oiling system works.
    Every few months, or at least every model year, someone questions the procedure, wondering why KTM made it so comparatively complicated, and why can't they just cheat... and not dick around with the frame fill/burp or-fuckin'-deal.
    If those same people would take the 10 minutes they spend bitching about the system and procedure, and look at the oil system schematic and read the point by point description that KTM provided......
    Or... maybe I'm being too presumptuous where mechanical aptitude is concerned. Perhaps, what skills and knowledge I take for granted may be an ability not readily found in others.
    Maybe I should remember that a common question means a common lack of understanding, and that figuring out an oiling system, although a natural process for me, is the equivalent of rocket surgery for the majority.
    I can't play a musical instrument to save my life... it doesn't make me an idiot, just a guy that has no aptitude for musical instruments.

    And so it goes... I apologize for almost tearing you a new one. :wave
