    I have been through this thread front to back a bazzillion times, it seems there is new/conflicting info on the re-mapping of the EXC ECU's.

    I am going to get my EXC reflashed and have been trying to get the correct info on the "proper" map to use.

    It looks like the unrestricted EU or AUS map is the one to load.

    There have been conflicting stories on the correct version to use. I understood the KM787EU12C0601 was the program to use IF using the stock exhaust, and the KM787EU12C0701 program was the one to use if using an AKRO or FMF exhaust.

    Can someone chime in if both will allow the use of the map switch and if the difference is in the fueling for the exhausts, or is the 701 the only option if you want the map switch.

    At this point I plan to keep the stock exhaust on the bike, I may install the map switch if the tune will allow it, but i mostly want the tune the XC-W has and will work with the stock exhaust.

    Thanks for clarifying.

    It seems the KM787EU12C0601has been superseded by the KM787EU12C0701Map and the switch will work.

    I will find out when i go to get the re-flash done.

    Thanks

    Well the bike did great in the wet this past weekend - rider just ok :D. Looks like the right side air box took in the most water and random swamp crap. Not enuff to bog it down but back at camp I pulled the cover and noticed where it collected.

    Swamp tatcis - skirting the sides to avoid the deep spots :deal. Every hole has a deep section - In this pix it looks like I just pulled out of it.

    Are you still using the stock exhaust on the bike? How do you like the way it runs with this map?

    Also, probably good to know whether the little perforated disc near the outlet of the muffler has been removed. The stock muffler flows really well with it removed.

    '0701 EU map installed with stock exhaust, JD tuner, desmogged and map switch. Works fine. Have had several maps installed. Hardly noticeable difference between any of the unrestricted maps. Only reason I went for the EU map is to allow the switch to work.... do notice the difference but I think it's over rated... you'll be significantly happier with any of the unrestricted maps over the original crap that is loaded on there.

    I have the JD installed as well, it really helped but the bike still dies off idle. Are you still running the recommended settings? And yes, the exhaust baffle fell out.

    Yes, except small screen at end removed & slight mods to internals at spark arrestor area. Yes, I love the way it runs! Haven't had it in the dirt since the switch install but rode it around my area with it. I can see where I might use the mild in slippery conditions but plan to leave it in the wild for most riding. It ran very well with just the tune before the switch though, big improvement over stock!

    Been away from this thread for a while and trying to catch back up,



    Dirty in all - Thanks for the reply with the link. I'll look into that filter and see if I can find anymore info on it. From the picture it looks just like a normal foam filter but I'm assuming its different in some regard. Like you I silicon-ed my 525 air box seams but found the silicone only bonded to the plastic for a few days before peeling itself off the air box and the gaps presenting themselves. When I return to the states in a few weeks I will be stopping by the body shops in search of plastic filler they use for plastic bumper repair as it supposedly bonds without the issues of the silicone sealer I had. Its not cheap as peanuts but if it will slow down the entry of the water I'm interested. I feel sealing off the air box lid will be key but it needs to be re-usable for air filter maintenance. I'll first be trying good ole fashioned duct taping the lid seams. So hopefully between the plastic filler on the seams and duct tape on the air box it'll make it a bit farther on the water crossings.

    A BOAT!!! I'm not quite that dead yet, still got miles of riding left in the body hopefully. My view is its an off road enduro bike and should be able to get across river crossings if they are below seat height. My Japanese MX bikes never designed for river crossings had no issues but my Race Ready enduro KTM wheezed to a halt faar to often. I'm silently hoping the 500 does not fear the water like the 525 did.

    I tried a K & N filter on a dirt bike 15 years ago and once it got dealt a thin coating of dust, it as you noted, choked out the motor by restricting the airflow to the point I could not even make it back to the truck one ride. Sadly the oiled K & N's work well enough in the clean air on street bikes but I feel they are inappropriate on a dirt bike.

    Put enough miles on my KTM to replace cranks, rods ,etc and yep they are not cheap. Just a shame the one piece air boxes I've used in the past never had these issues but KTM's air box on the enduro bikes leak like a sieve.

    Good progress. Hopefully you have better quality Silicone or one that bonds better than the stuff I used on my 525. After a few days pounding about offroad it was peeling off the airbox. Keep us updated on the progress.

    Hey guys I am thinking of joining the 500 club. I can't read through the 200+ pages. Is everyone still happy with the bike, any problems or issues I should look for when shopping. Thanks.

    You should really get yourself a 70° Berg Justin! :wink:

    How about using an oiled foam pre-filter on top of the K&N, is there such a thing available that would fit? I know that this is the way the 950/990 guys like to do it.

    Running pretty close to the original JD tuner settings. WIthout the JD I still get a lot of flame outs even with the re-map - with the tuner only the occasional one. The bike is pretty good now with this setup. The fuel injection/tuning still doesn't feel 100% like it should though. I had a 2009 KX450F and the fuel injection/tuning was much better. No flame outs ever and consistently crisp and agressive response every time you twisted the throttle from anywhere in the rev range.
