Problems with 02 520

I was wondering if anyone knows of any problems with the 02 520's. Things like decompression bolt, cam bearings and so on. I know that I have heard that the cam bearing thing was supposed to be limited to the 01's. Are there any concerns and if so, what is required to remedy the problems?


I'm actually looking for the same information since I'm looking to buy a used 2002 EXC 520. What are the major things to look out for on this bike?

The only problem I've had is that it's to much fun :)

I have a 02 520 sx. Just getting back into it after 20+ yrs.Harder than I thought to start over! :D

I looked at the posts for months before deciding on what to get. Between the 520 and crf 450.Found nothing on the 02's 520 You'll love it, your'e friends will to. Do a search on 520.


The only problem you will have is the "breaking in your ass/the seat". The combo of slick/hard seat and the sheer hp this bike has was pretty humbling the 1st day. It will definately teach you throttle control and to hold onto the tank with your knees.

I've got a 520sx. The 1st day on the stock seat was torture. The 2nd day was better (my friends still complained when they rode it). Common break in for the seat is about 10 hours of riding time.

I bought my 02 520 E/XC new and have ridden it for over a year now. Except for having to replace my fork seals

a few times I have had ZERO problems. The bike still runs great! Hope this helps a little.

      I have a 2007 450 EXC that I recently installed a new clutch slave cylinder on. Per the 2007 KTM service manual it clearly states that the clutch needs to be filled with hydraulic oil, which I did (magura blood). That was yesterday. I went out to double check the level today and when I removed the cover, the rubber seal was all contorted and out of shape. I then looked at the cover and it's a Brembo clutch and says "DOT 4 brake fluid only".
      I flushed the line and the master cylinder about 7 times with DOT 4 brake fluid and there was no sign of the magura blood left in the system. My question is: other than the rubber boot on the master cylinder, what damage might have been done by putting in the hydraulic oil? It was in for about 24 hours.
      Thanks in advance for any advice!

      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?
