Metal shavings?

<font color="orange">Is it normal to be pulling out metal shavings with the magnetic oil drainplug? My Dad has changed the oil in his 2001 KTM 520 EXC about 8 times now and metal shavings are still coming out with the plug. There has been very little to no shavings in the oil filters.

Changing the oil today, a sliver of metal approx. 1/4" long and about the width of a small safety pin came out on the plug. This just doesn't seem that it could be normal after 8 oil changes. The piece was textured with very small lines in it, looking to me like a piece from a fiber clutch plate, but I'm not sure if the fibers have some steel in them or not. (making it possible for them to attatch to the magnet) Otherwise, I'm not sure where it could be coming from.

I understand from experience with my YZ426 that SMALL metal shavings coming out on the filter is normal but I have never seen anything that large on my oil filter.

If this is normal, even after that many oil changes, then I think I should and I will consider a magnetic oil drain plug for my YZ426.

Thanks for your help!



I don't know if it is normal, but my 2001 400 did the same thing for about 6 months. Now I only get the black micron metal on the magnet. I have not seen any problems with the bike and it's 8 months old. I have talked to other KTM owners (two and four stroke) and there bikes have done this as well.

I agree with Otis although I haven't had any large shards come out of my RFS. Well, after the cam bearing blew up I had a couple but I expected that.

Did you replace your cam bearings with sealed bearings?

Yes I did. I got the updated bearings from KTM in nice KTM boxes. Pretty reasonable about about $9 per. Turns out, they're just standard sealed bearings I could've gotten from the local bearing house. Still, I wanted to be certain I was putting the KTM blessed bearings. Much quieter now.

<font color="orange">Otis, approx. how many hours do you ride a month? We ride generally about 20 hours a month and he's had hid bike for about 6 months now. Thanx

      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?
