ktm lc4 400, metal in oil

[The Stranger:Me]

I drained the oil today and found this on the magnet

Fark, who'd put a 20c coin in an engine?

your sposed to put them under ur forks

My magnetic plug always has a bit of fuzz on it by the 5000km oil & filter change, but nothing shaped like those pieces look/ like you describe.

What it is, and what to do about it, are two questions beyond my expertise, sorry!

I cut up the oil filter and it has collected quite alot of small particles (looks worse in the photo)
After this filter the oil goes through a 'dunny roll' type filter which will have trapped any real small stuff.

Does this mean I can just replace whatever is buggered or will I have to strip the whole engine and clean it ?

strip it down

If this was a DR650 I'd say third gear was on the way out...but there's really only one way to find where those bits came from. Pull it apart and inspect.

I usually throw a few handsful of them in the sump ...Theyre cheaper by volume than that fancy synth oil .

[LBD]

Looked at your filter photo...yes I would say it is worst case...it does warrant stripping down....

[Underground]

OK , thanks for all the input .
I've started stripping her down and the motor's going on the bench
All that metal is coming from some place that its not suposed to be coming from.
Motor in and out looks like a doddle compared to doing my Africa Twin last year...that motor took a lot of beers to remove , and a truckload more to reinstall

[LBD]

Good luck, keep us posted


At least you did not have this much to find...

Go on.....thats just molybdenum paste in it's early stages of formation, it'll be fine.

Good call Underground, your regular oil changes have paid off in catching this early rather than when the entire engine is full of filings. Let us know the outcome so we can gloat, oops sympathise.

And pass the Tui's while your at it....

Rainy day yesterday so I put the motor on the bench and disected it.
Not good unfortunately
I couldnt pull the cylinder off through lack of a 15mm spanner ,but there is play when I turn the crankshaft back and forth -meaning buggered big end/small end.
And there is what appears to be a crack around the bore
See pics .

[Crisis management]

Sorry to see that, it sounds a bit nasty and certainly the cylinder crack is unusual, any idea why that should happen?

No idea , I suspect it has been like that since I bought it (assuming it is a crack) because it has always small amounts of coolant .
Can only think that someone in Japan was unkind to it in its previous life.

strange you can still see the honeing marks
