    i have a question but not really sure how to word it so ill try my best.
    why is it only 1 liter without filter changes?
    i don't understand why we originally need to fill the filter housings with oil and still top up 1.2 liters so in total 1.2 liters will be inside the engine but w/o filter changes, considering there is oil already in the filter housings, if we top up with 1 liter, there will only be 1 liter inside the actual engine. it doesn't seem to make sense or is a bit inconsistent.
    so why do we need to put 1.2 liters + fill up the filter housings one time and the other time, when there is oil already in the housings, we only need to put in 1 liter?? when originally regardless of how much oil we put into the housings, we still need to top up with 1.2 liters???

    it kinda defeats the purpose of doing the original step and putting in 1.2 liters to begin with PLUS filling up the filter housings anyway and a bit contradicting because when we aren't doing a filter change, there is still oil in the housings so the 1 liter we put in, isn't going to goto those housings, so if we need to fill up with 1.2 liters originally when we are doing filter and oil changes PLUS fill up the filter housings, wouldn't it still be the same if we are to put 1.2 liters in regardless(considering there is oil already in those housings)...because if we have to put 1.2 liters in aswell as fill the housings, it makes more sense to put in 1.2 liters when there is oil already in those housings(just as we would with a filter change) and putting use to the 1st step which is filling up the housings anyway.
    that's the best i can explain my question, i hope others can understand what i mean or am trying to ask/get at.

    Put the coke away!

    1L without filter change, 1.2L with filter change. You're over thinking it

    I use 1.2 liters for a full filter change.

    I "pre-pour" the 1.2 liters into my fill container.

    Then I soak my filters in the fresh oil sitting in the container, then install them.

    Pour in the remaining amount into the bike.


    Viola. Still only using 1.2 liters.

    yeah i get all that but i was just wondering why, as it wasn't consistent and contradicts what the manual states and why we have to do that step originally, even though when installing new filters you still put 1.2 liters in the bike plus fill up the housings making it more then 1.2 liters anyway and just can't see how it's any different if 1.2 litres is meant to be in there anyway WITH the housings filled. i am just a deep thinker lol

    Rules were made to be broken?


    As long as you're good, via the sight glass... Why worry?

    Its not 1.2 plus fill the housings. As stated, when doing filters, pre pour your 1.2, fill the filters half full or so, place back in housing. tigthten cap, pour the remaining 1.x into the engine.
    don't rely on the sight glass

    ok cool. fair enough. ill listen to what your saying but all i was saying is that that's not what the manual was saying. nowhere in the manual did it say pre pour 1.2 liters. it says fill the filter housings up then fill in 1.2 liters of oil. that's where i was confused.

    I see where your confusion is.

    For what its worth. I change my oil/check srceens @ every 15 hours (or less depending on use) and my filters every third change. For the oil changes,I measure the amount that comes out and replace it with the same. When I do the filters, I premeasure the .2 l in a measuring cup and use this to fill the filters. I then add the remainder. I know that I've always heard 1.2 with filters, 1 without ,on ktmtalk and adv and so I have done it this way for quite awhile. Its an 04 with 412 hours and 12,800 miles.
    Enjoy it. They're great bikes

    I think I have finally figured out the oil capacity on my RFS, but my problem is how to avoid getting oil EVERYWHERE when I do the filter change with the bike on its side. It is the worst oil change procedure I've ever seen, and I've owned an oil-in-frame LC4. I'm curious what tricks people have come up with to avoid that puddle in the garage (other than cat litter, duh!)

    I'm curious why you feel it's so torturous. A full change took me 20mins, and the more common drain/fill takes under 5-10mins.

    How do you not get oil everywhere when you open up the filter housing?

    Not when the bike is on it's right side, no.

    I see. I took the filters out before laying the bike over, that was mistake one. Mistake two was slightly misjudging what "half full" was when pre filling the filter housings. I'm due for another filter change in the next 10 hours or so, I will try to do this one right!
