    The dirt/dual sport miles are easy on the engine but the 200 hours as a snowbike are full open, full load most of the time.
    Upon tear down the rings had .017 ring end gap (service limit is .004).
    I thought I would need to change the piston but it is well withen service limit and the cyl is like new.:clap
    Changed the valve guide seals for good measure. It is suprising how well these engines hold up.
    I use Mobil 1 15-50 engine oil and a good motorcycle trany oil and change the engine oil often.

    I just got off the phone with a guy whos been dealing with and selling KTM since 1970.

    FYI: So Im told 2011 530exc still has the seperate oil sumps for the motor and the trans.

    1# cause of early 530exc motor failure is not getting the air filter snapped in place right. Dirt and dust by pass it with ease. Use non-water based oil on the filter when hitting streams and such. To do so will will result in sucking in dust after things dry out while riding. Top end becomes toast.

    2# Use streight dino oil no synthetic during 530exc break in. First 3#hrs riding then change, another 3 hours then change, then the final 3 hours for a total of 9 then change and run a synthetic if you wish. The rings have to be seated well during the breakin or you will burn oil no doubts. Those who don't do this are the ones who he says start the complaints about ring issues.

    It makes sense to me.

    Someone chime in here if something seems out of place with this info so as to cross check it. :hmmmmm

    That all makes sense to me but I am a smart ass. Therefore, I must point out that in 1970 the machine was called a Penton...

    You mean Penton as in "John Penton", the guy who imported the 100cc
    Berkshires and 125cc Six Days both powered by Sachs german built motors in 1968:eek1............................Now you don't have to feel alone any more brother.:freaky

    Hey, how is your ODO mounted?

    This is the closest pic I have without going outside in the -5C for you!

    In this pic I have it tie wrapped to my RallyRisers, which actually worked fine.

    [​IMG]

    But my machinest buddy wanted something a bit more robust so he tapped and threaded into the horizontal bar of the Rally Riser I mounted it there with the bottom 2 holes under the computer.

    This pic shows the bottom 2 holes that the computer normally uses to to that bracket, and I used spacers so that it stayed straight otherwise it would angle forward once the bars are in place. It is also about 1cm higher than what you see in the pic below.

    If you would like more specific pic's let me know and I'll shoot them tomorrow when it is light outside.

    Thanks Osteo, thats great.
    Its given me an idea how I can raise mine. :thumb
    I have pretty tall risers. With the risers + PHDS bar clamps, the bars are 3 inches taller than stock... I have to lean right over to see the ODO :lol3

    I hear you! originally in the position above the only time I could see the ODO was standing, now I can just see it while seated, so it is perfect. When my buddy tapped that horiz bar one side was off a bit (a bit difficult to tap that smooth round bar) so there was some shimming done, but you can only see it when the headlight is not there.

    Just got a 2010 530EXC home and went to do the muffler mod. The parts manual shows the Silencer endcap with a screen and a threaded ring. Is the mod just to remove the screen or does it involve cutting the pipe within the endcap? Thanks for the help.

    Ditch the screw on screen on the end, that's just for noise reduction. You need to remove the end cap from the can and cut the tip/restrictor off inside that looks like a washer that's welded on the end. That will open up the exhaust and let it breath like it should.

    Out of curiosity why would you want it installed? It does little for noise and is just one more restriction that you can remove. I might have mine laying around some where...I'll look.

    I find the reduction in sound to be noticeable and can't really feel a difference in power. I like to keep my bike as quiet as possible.

    I made the offer because I find it near impossible to keep these things in the muffler though. I've lost two already. Was even thinking of tack welding it on.

    I agree, I think that screen is about 2dB worth or reduction, and as I also ride my bike to and from work with most of that ride through a residential area I just don't want the noise - even though it does seem to make a bit of difference with power (at least to my seat of the pants). I have gone through 3 now. The last one I put in the vice, made it a bit oval and scored the threads + heat locktite and it still eventually came out. I'm going to safety wire this last one in place.

    I bought a 530 in December and am digging it more every day. I have gotten the placement of the bars, steering damper, and bark busters where I like. I would like to get a little more room for my hands, because the cramped area doesn't allow much room to alter hand placement and creates some post riding wrist pain. Maybe a different "back sweep" angle of bar would help?
    I also want to eliminate OEM kill switch and install a small "push button" type kill switch on the left bar it to the inside area of the left bar. This will allow for more room on the right grip area after moving throttle assembly further to inside of bar. I am looking for a "narrower" light/turn /horn switchgear which will give more room on the left grip. Maybe even eliminating said electric "gizmo" all together, but at this time , elimination would not be my first choice.
    The innovativeness and knowledge of this forum is without comparison and proves a great benefit to its members/riders. Thanks to all contributers.
    The 530 is my 4th KTM and , by far , the most versatile and enjoyable yet. With gas prices on the rise, any reason to ride this bike is OK with me.
