'04 400 EXC

Does anyone know anything about the '04 400EXC :) I'm looking at getting a new bike in April and was looking at the 450 but then I saw the 400 was coming out. :D Any help would be greatly appreciated :D

It's the same bore & stroke as the original '00-'02 400 EXC with all of the current chassis, suspension, exhaust upgrades, etc. as the rest of the '04 EXCs. A lot of guys preferred the quicker revving, shorter stroke (by 8mm) power delivery of the 400 vs. the longer stroke 450, so KTM is offering the 400 EXC for '04 again in limited numbers. They might be tough to get, depending on your location and who your dealer is. The 400 can also be modified by installing the optional 453 kit which increases the bore, but retains the original shorter stroke. It's the set-up that Mike Lafferty rode before switching back to the new two-stroke just recently. The stock 450 EXC is an excellent bike. The re-launch of the 400 EXC simply illustrates the "different strokes for different folks" brand of thinking that KTM has long since been noted for. Choice is a very, very good thing!

Thanks Slayer.......I was wondering if it was the same. :)

The 400 has ALWAYS been available so there's no "re-launch" at all. It's made in very limited numbers for some race series or other in Europe. There's an ISDE class called 400cc four stroke and I think that was all that was legal last year. Apparently they allow 450's now but still call it the 400 class.

I owned an 01 400E and own an 03 450E and I never noticed one iota of difference in the revability of one motor over the other. They're almost identical in lowend power but the 450 has more power in the middle and on up. I'd personally go for the 450 just from a re-sale point of view. You're sure not gaining anything, IMO, by getting the 400. Almost the same price new.

As to what Lafferty was riding, who knows? There are a LOT of different rumors about all the configurations of bikes he rode last year.

Thanks Jeb. I am looking forward to my first KTM and want to get all the information I can about the different bikes. I'm 99% sure I will get an EXC but haven't ruled out the MXC yet. I took a quick look at your web page and it appears I can get a lot of info there. I may be asking you a few more questions in the very near future. Know anything about the 50 Sr Adventure? :)

I'm happy to answer any questions I can but I know nothing about the KTM's under the 125, sorry. KTM wasn't on the radar screen when my now 19 year old son was growing up so he's a green rider.

      Hi Folks!

      Sorry if there are a bunch of threads already but I used the site's search function and didn't find anything so far...

      I just found a decent deal on a '14 350 EXC-F with 11k km (unknown hours). Has a few goodies including skid plate, hand guards and it's for sale for about $2k CAD less than a '16 with 6k km on it.
      The bike is in showroom condition (appearance) with no indication it has been offroad at all.

      What would be the gotchas that would make this deal realistic? I'm coming from a WR250R where the engine lasts forever, is 11k street kms high for these bikes? 
      Are there any big defects in the '14s that I haven't dug up yet?
      With no service records what things should be done, checked, etc?

      I purchased an '06 525 EXC some time ago, and recently pulled the motor out of the frame to address some other issues. When I removed the clutch slave cylinder, I noticed an issue the previous owner neglected to tell me about during the purchase.
      It appears that at some point, the chain broke and damaged the engine case near the clutch slave cylinder (see pics, please). I have noticed that the clutch does not fully disengage (bike lurches a bit going into gear, neutral is hard to find... its worse when engine is cold) ... I did not notice any leaks around this area (mineral oil or engine oil) before or during disassembly. 
      The previous owner (or someone) repaired it with some sort of epoxy.
      Without doing my due diligence (checking clutch fluid level, bleeding) I hesitate to state that this is the cause of my clutch disengagement issue ... but pardon my ignorance here and help me out: How bad is this?  Am I looking at replacing my engine case here or is the previous owner's jerry rig good enough?

      SO, for information sake and to power the search engines with some key words that i couldn't seem to trigger during my research...I'm posting my desmog process on my new 500exc. Being a new bike...i wanted to make sure that all of my "doings" were going to keep the short excuse for a warranty in tact. I have part numbers for the plugs, washers etc as well as what all came off of the bike. I know it's a simple process for some, not so for others and would like to give credit to the advrider.com writeup for some great info.
      Long story short...i plugged the hole left from the smog pump thingy on the right side of the cylinder, the Secondary Air System (SAS), the overflow canister, and all the hoses/wires that go with. The electrical plug that was involved I simply taped up with grease in it and strapped it to the inside of the frame rail.
      After i took all of it off, it would not idle....i turned up the idle adjuster (to the left) or counter clockwise in order to increase the idle speed.
      Result!!!!!! NO popping on decal, no stalling after hard accelerating, etc. Sometimes after much creeping and low rpm riding it will load up and flame out. I plan to try a different map after i install my exhaust. I think a new map will be able to add some rev to the top end. Right now it seems kind've flat once you pull through the sweet bottom and mid ranges. The bottom end power of this bike coupled with the silky smooth clutch action makes for the easiest and best suited off road bike i've ever been on. It does what i need it to do!
