ktm 500 exc?

I saw this , http://shop.ktm.com/usa_en/powerparts/airfilter/water-protection-for-air-filter-1.html but I also thought I read somewhere there was a mesh version that was small enough to prevent water going through yet let enough air. The only mesh version I see now is for dust. I didnt look into it what so ever but if you have the seat off and maybe the battery out can you get your hands into the airbox , so the side cover remains intact, to seal it up with some grease or even a nice thick finger bead of silicone? I have great success with getting large beads of silicone off easily, it's when I use small amounts it becomes impossible glue. Grease in all the seams and gaps I would think would slow the influx of water. The top of the box is wide open if I recall. Like you Im used to rubber air boxes that squeeze onto the throttle body/carb and get a spring in the groove with a snorkle on top right under the seat. This is new to me as well so take what you will. My crossings altho deep have never been very lengthy. Maybe 100-200 ft. My uncle would just scream at me " GO FASTER, DONT STOP! " :)

why not just get a boat if youre gonna be riding in water like..

Yep, it works good.

Download the KTM 500exc European manual and it explains how to use it. Its not in the US manual.

Thanks for the info!
I downloaded the manual, where does it explain how to use it?

The K&N filter (oiled cotton) will not pass water. It will choke out the motor first.
BUT, the adapter the sell for the KTM's in the past sucks, it will pass dirt. Good filter, bad application.

Foam filters let water right in. The con-rods on these bikes are VERY expensive.

Re-think that boat.

Thanks guys. I removed the seat, turned off the lights and took a flash light to the bottom of the air box to find the big gaps and taped em up - not too many. The air box seals pretty good (not as good as the LC4) and most the gaps were on the left lower side. I only covered the lower half of the right side - looks like that's a big breatheing spot as well as the top under the seat. If it does not choke the bike up I'll replace with silicone.

Thanks for the links! I cannot do the mod myself, but for those who can, it's a wonderful information!

OOPS - The info is in the 2012 manual. KTM updated their website to 2013.

Page 13 - map switch operation. The switch under the seat is the one you need. The handlebar switch isn't necessary.
There is a plug under the seat that is for the map switch.

Thanks, found it.

Thanks for answering my questions, guys. I put the switch on & wow, does it make a difference. Wild is a good description for that position! Way too much fun to ride that way! Must be illegal! Thanks again.

I must have missed something, where did you get the switch? I have a 13 500 EXC.

It's the Trail Tech switch, bought it thru my dealer.

Thanks, I'm going to try one of those.

Remember, it won't work with the stock map, I have the euro map in mine.

Will it work with the XC-W map? I have the XC-W map installed in my '13 EXC.

yes it will.

Nope

http://www.trailtech.net/map_switches.html

and btw, the competition map code shown on TT's site is the old version

new version for the 500 xcw is KM787EU12C0701

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.

You might find the answers you're looking for in the following thread

http://ktmtalk.com/index.php?showtopic=463906&st=0

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
