Is that what your father told you, "son, when you out there, take care your rubber!"? :lol8:

That's not the point, isn't it? Or don't you get it? But maybe you are not interested in reading a field report. Or maybe it is just the wrong forum. If at all that's what could make me upset,...

What else did you inspect at 800km?
Is it necessary to tighten the cylinder head screws? My dealer is saying it would not be necessary, but I am doubtful. :confused1:

Swarf from your bike is very similar to the BJ, but much less in quantity.
Most likely (and hopefully :rolleyes1:) the swarf is from the gear box. Anyway, on most bikes, gear box and engine are...
