In any event, I can understand why the guy who posted this on Facebook is pissed; I think most of us would be if something like this happened. However, if this is actually a six year old bike (based on it's location and paint job), expecting Yamaha to pay for a new engine is pretty unrealistic. And I certainly wouldn't default to the "it must be a manufacturer's defect" excuse, unless the defect affected only one bike in the 12 years that the bike's been made. I haven't been on the forum as long as some, but I have been around for almost eight years, and I've never heard of this happening to anyone. Sometimes stuff just breaks, and sometimes you're the unfortunate dude who owns it when it breaks.

when a new connecting rod or main bolt is tightened, it is practically impossible for it to loosen. When "the same" screw is tightened again (in a repair/disassembly), that screw is already "stretched", if it is tightened according to the recommended torque, the screw itself will no longer have the capacity to sustain that torque in the time, the screw It has already lost its initial elasticity. The washers that are used in this type of screw are usually flat….because the clamping tension is exerted by the screw when it is “new”….
The con rod bolts are tightened to a specific angle after the initial 20 Nm torque rather than a final torque as you just cannot trust a torque wrench to get it right, My guess is that these bolts are tightened to 90% of their yield and the manual comes with a big warning to replace them if you have gone too far. This tightening is common practice in the marine indusrty where i reside for the more critical components. The recommended torque for the bolts you buy over the counter only goes to 60% of its yield. So yes, it sounds like they, or at least one, has been over-tightened.

Agreed, my ‘16 has the same colors and there is not enough information. And IF it really is in Turkey, no way that it costs €10K. People in Turkey with a normal job make around €300 per month, labour is cheap. Brain fart: Sounds a bit like some GS bloke trying to bash the S10. Just like we (i) do to the GS.

I don't think the guy on Facebook ever mentioned the year of the bike, but based on the paint job it's either a 2019 or 2020 (can't recall which year they went to the blue rims).
Am I missing the part where he said it was 6 years old?
I‘ve seen it somewhere, its a 2016. He also reckons it has 4yrs warranty as std where he’s from, and therefore only just out of warranty……

The year is unimportant. What is important is the mileage which at 60,000 km is very small and puts a question mark on the original post in Fakebook.:D
