EXC - emissions, gearing,street, rims are "supposedly" not as strong
And a different ECU, stock with an off-road-only map that can be more easily changed.
the EXC ECU is locked
XCW is NOT
The rims are plenty strong for hare scrambles and the rock ledges I have encountered (lots). I don't think these will be a problem.
The stock ECU cannot be modified with a map switch such as the one from Sicass that I have on my bike. However you can burn a new code in the ECU from the XC-W (the US code ends in 0701) and then you can mess with the ignition mapping. You can also use the JD Jetting Tuner 6X to increase fuel in the mid and upper end. (I am still messing with that.) That is, you can get the XC and XC-W performance out of your EXC. You have to be willing to consider racing only use for it, however,to be legal. Scofflaws can do what they wish.
The stock ECU on the EXC can work quite well with the JD Jetting Tuner as has been reported in this thread. You can stay with that and have very good performance as well.
Sorry if the answer to this question has already been answered on this thread but here goes.
Has anyone remapped, desmogged or removed the AIS on a 2013 500EXC? I read in an earlier post that there is now a LAMBDA sensor on the exhaust on the '13 500EXC. Is there now an error code if anything is removed? There is a LAMBDA error code listed in the 2013 manual and there is none listed in the 2012 manual.
My son and I took my '12 and '13 500EXC's out for a shake down ride up to 9,600 ft elevation last weekend to see how they compared. The '13 was all stock and the '12 has the 0601 MAP and the above stuff removed plus an FMF muffler. The '12 ran perfect at all elevations with no need to adjust the idle.
The '13 ran good up to 4,500 ft and then wouldn't idle so I set the idle up but it still ran rough at idle. I set the idle up more and then as I climbed in elevation it started running better so I set the idle back down some. As I rode back down hill from 9,600 feet back to 4,500 ft I once again needed to adjust the idle but not as much this time.
Once back to 200 ft elevation, I once again needed to adjust the idle on the 2013 500EXC. No adjustment of the '12 idle was needed at all and it ran perfect at 200 ft all the way up to 9,600 ft and back down again.
I am interested to know what has been done successfully so far to the 2013 500EXC.
My 13 500exc has no lambda sensor, I removed the sas, and removed the evap system completely. Did not remap, had to adj. the idle setting at first, now it runs great, have not had to readjust. I ride from about 400m to 2500m, even at sea level, no issues.
Try cleaning the fuel filter inside the fuel line. I think its at the quick disconnect on the 2013. My experience has been that when the bike starts idling erratic, the filter is starting to plug up. The bike will run just fine everywhere else.
Big Adv and BP:
Thanks for the feedback on your '13 500's. I will check the fuel filter when I get home.
"It idled rough and then got better", sounds like it could have been a clogged fuel filter. I could have checked it on the trail last Saturday but I didn't think to do it since this was the first tank of fuel and fresh gas was put in by my dealer and I topped it off at the gas station. I suppose there could be some plastic shavings in the fuel tank, since it is so new, and I did not make sure there was no loose stuff in the fuel tank before my ride.
I plan to remove "the stuff" to make room for a 4.0 gallon (15L) Safari Fuel tank I hope to have in the next 6 weeks. No prices yet on this tank and I will have to pay a premium to get it that soon or wait until January.
If anyone has installed the 5.3 gallon Acerbis and has also used a 4.0 gallon Safari tank on an older KTM 525, I'd love to get a comparison of the two tanks since they both use the shrouds for fuel. My friend has a 2004 KTM 525 with the 4.0 Gallon Safari fuel tank and I'd like to know how that tank compares with the Acerbis 5.3 as far as width at the knees.
Another friend of mine had the 6.6 gallon Acerbis fuel tank installed on a Honda XR650R and it was just too big and he regretted buying it and last year sold that bike and bought a 2007 KTM 525EXC with a 3.1 fuel tank. He loves it but has to carry extra gas when we ride in Death Valley.
I know I like a 4.0 gallon fuel tank but just don't know about a 5.3 for my 500EXC's.
You must have some amazing scenery where you ride in B.C.
B.C. is one of my favorite riding destinations on my street bike. Rode to Bella Coola in July of 2011. One of my best trips yet. http://www.youtube.com/watch?v=_fSbd8eCgqE
But, I left the KTM at home. Taking the 500exc to Death Valley in a few weeks for a 4 day dual sport ride. I will have to carry extra gas since I don't have a big fuel tank yet. Can't wait.
This is one of the areas we will be riding in: http://www.youtube.com/watch?v=0pghyXkGOLE
Nice vid! Yes, it is a great place to live and ride. I have just moved here, so just starting to venture and explore. But have rode many of the paved roads in the area in the past.
Seeing as your bike is new, I would give it some time to break in and see how its running. The dealer may not have done the idle learn to it before you got it, so it was still learning on your first ride.
I have a 2013 and have not remapped or piped. I removed all of the emissions equipment and used the Blais kit for block offs. I have had it up to 6000 feet and at sea level and have had no issues. I don't believe I will remap or pipe it. It has plenty of power already. Prior to de-smogging, it popped, faltered and was unreliable with elevation changes and difficult to start if I dropped it. It is perfect now. Just needs a better rider :)
I got a second set of wheels for my XCW and now I can fool people into thinking it is an EXC
EXC's have black spokes...no fooling a true enthusiast!
Thanks for the info. Glad to know the '13 can be cleaned up with no issues. Does anyone know the MAP numbers for a stock 2013 500EXC and a stock 2013 500XCW?
Still waiting to hear if anyone has installed the Acerbis 5.3 gallon fuel tank and how they like it. I'm concerned it might be too wide at the knees, or too bulky of just too heavy. 4.0 gallons is also too much extra weight and bulk but I have been able to live with that on my prior DRZ400S to get a 200 mile fuel range I need when riding in Death Valley.
I will know much more about MPG in a few weeks after spending four days in Death Valley.
The 2012 500EXC's have black rims and black spokes.
The 2013 500EXC'c have crome rims and black spokes.
The 2013 500EXC's have an additional FI light error code in the manual that flashes 4 times slow and 5 times fast. This error code is not in the 2012 500EXC manual.
2013's have silver/natural colored aluminum rims with black spokes, they are not chrome.
whoa this is getting picky. look what you started saltydog!
i'm willing to bet by "chrome", 2on2off just meant "not black".
That's right, but I can be corrected. I'm all for accuracy and I wasn't 100% sure what the rims were other than not black.
I have gotten the best information on setting up my 500 from this thread. Just about everyone I come into contact with on advrider.com is very helpful with great information.
Keep it com'n.
absolutely! this is hands down one of the best forums with the best group of folks out there!
No black spokes on my 12?
