Fantomas, I'd go to another dealer.
Your clutch is a wet clutch, so burning the plates would be really hard in just 3500 km, unless you spend all your time drag racing.
My bet is that the clutch cable isn't adjusted properly, which will cause rough and noisy shifting. That coupled with the fact that these bikes are notorious for notchy shifts when they are new.
http://www.cyclefish.com/tech_tips/l...utch_cable.asp is not a bad place to get an idea on how to adjust your cable, but better still, get a shop manual to show you exactly how to do it. It's really the first thing to check with hard shifting.
