Looking at 2011 FS570 producing some steel shavings. What's likely wrong?

I've wanted an FS570 for a long time, ever since they came out.

I recently decided it's time to buy one, and asked a friend who has one what problems to look out for.

In reply, I got:

I've still got mine and was planning to take it to a shop the second week of July to have them get it road worthy for sale since I'm clearly not going to ride it. It's a FS570SM. Still needs to be run through from top to bottom, there were some oil shavings in the pan on the prior 2 oil changes (15ish hours of engine run time), rear tire is toast and brakes are totally soft after sitting. Want to buy it as is? I'll cut you a hell of a deal.

I'd like to get in the $2ks and big enough that it could need a trans and/or motor rebuild but might not.
...
Less than 5k miles, probably less than 4500, not sure on hours. Bike has FMF exhaust, trail tech computer, seat concepts seat, J&D jetting fuel programmer.

'11. They stuck to the drain magnet so I'm guessing steel. It's entirely possible it needs both a motor and trans or it could just be the clutch dying since the hydraulic clutch wasn't adjusted well when I first got it.

Obviously it's possible that it needs quite a bit of work, but it's also possible that it's nothing abnormal - I know KTM thumpers are also prone to producing some debris when it isn't anything significant.

What's likely to go wrong on these? I'm not afraid of splitting the cases, although it's been a while since I've done so.

If I decide it's time to pull it apart, and it's not worth repairing, I'd probably use it as a parts bike - I race a KTM so it shares a bunch of parts.

I also came across a very nicely sorted FE570, with the 70 degree tank, HDB handguards, Akra, XL Pro headlight, etc for $4500... but I'd need to pick up SM parts for it. I suppose that, if timing works out, I could swap the FS parts over to the FE (and swap back on the occasion I want to ride dirt - this will be mostly SM). I'm awfully tempted by it given the tank, I know they're impossible to find, but I don't really have space for 2 bikes (otherwise I'd likely just buy both right now) and converting it to SM isn't cheap.


I'd appreciate input on what, if anything, is likely to be wrong with the FS, and if it's a bad idea to pick it up.

lets say I crack it open and find what it is... is there anything likely to be bad that isn't available?

One of the things that's bad is the clutch master.

Is there a reasonable clutch hydraulic system upgrade for these, or do I just get OEM parts?

The bike is generally pretty clean (other than having been sitting for 1.5y), but there's some corrosion and apparent fluid leaking from the clutch master, which is why I was thinking it needs a master.



I know on later Huskies the thing to do to fix the clutch setup is replace the parts with KTM parts, didn't know if there was something similar with these.

also, it isn't entirely failed - clutch won't fully disengage, but it'll disengage enough to start and idle (with some drag), rather than spinning the tire on the dirt I was on (with a bald 17)

I got a clarification that it wasn't so much shavings as just some fuzz on the magnet.

Regarding the clutch, there's probably at least an inch of free play. I'm assuming that isn't normal. Between that and the condition of the master, I imagine something has failed.

The part # for the clutch slave is 75032061044 (at least on Munn's fiche)

Oberon lists a unit for that

https://www.cjdesignsllc.com/about-us/brands/oberon-performance/oberon-ktm-lc4-clutch-slave-unit/ states that it fits a bunch of KTMs, including all the smaller bikes and 690s (although I assume not the new ones)

does anyone run one? given that it appears to be a common point of failure I'd rather go with something less prone to problems.

Apparently it was very fine, which is part of why I bought it.

I'll be putting maybe an hour on it, dumping the oil, and seeing what I get. Don't want to do any more damage than has already happened but also don't want to waste money.

Is there a common clutch master upgrade, given the condition of mine, or should I rebuild it?

I'd found the slave, and am planning on going that way. Given that it looks like my master has failed, I was wondering whether there's an upgrade at that end too.
