he was referring to chain stretch NOT slack, in his case I would stick to the manual and replace itThere is no need to worry about an extra mm of chain slack. I think you will find a lot of the riders on this forum keep to the long side of the recommended slack, or even a few mm longer.
Lot going on here so let me take the chain issue first. If beyond the recommended specification on pin to pin distance, I would replace the chain and sprockets. They don't give any warning beyond showing you they have stretched that much when it comes to them failing. A broken chain can often ruin the bike as on the DL 1000 it will often shear off the clutch slave cylinder mounts and that cannot be easily fixed.Hello, thanks for all the input. I went for a 30min ride today around town and afterwards I noticed that the oil (in the sight glass) is foamy on top. The temp gauge was normal, mostly 2bars, at the end of the ride it was 3bars.
Foamy oil is not a good sign I presume, right?
Yes, I mis-read that. Pin to pin stretch should not be ignored.he was referring to chain stretch NOT slack, in his case I would stick to the manual and replace it
I changed it last year and only done like 1000 km with it
It might be worth revisiting my original mistake on this thread. Did you measure the chain stretch (the distance between 21 pins, not sure what the spec is on this bike, but my 2nd gen wee is 319.4mm) or the chain slack (how much the chain moves up and down in the middle of the run, in the 20 to 30mm range with the bike on the side stand). Please forgive me for putting these definitions into the question, but like @BackPacker, I'm having trouble imagining a chain wearing out that quickly, and thought perhaps a language issue might be the real problem.I can only think of two ways to ruin a new chain in such a short time. One is to adjust it way too tight - and that should probably kill your countershaft bearings as well -, and the other is cleaning it with a pressure washer.

I have no idea which chain it is because my previous mechanic installed it and never got me the receipt. I changed the mechanic and he told me that the chain was ok. But I have trouble now trusting mechanics because they screwed me over a couple of times and I like to check things on my own now. The mechanic who told me the chain was ok obviously didn't check the chain, otherwise he would have told me that the distance is on the limit. He also told me my radiator doesn't have a fan, then I checked on my own and of course it had one.Did you get a brandname chain (DID for instance) or some cheap Chinese thing off eBay? A proper brand name chain suitable for your bike (525, O- or X-ring), properly installed and adjusted, should not show any signs of wear after just 1000km, even if you did not do any maintenance at all. To me this sounds like a warranty claim.
