Slowly but surely the dreaded whining noise has developed. At the 18000km service I asked the dealer about it. It was just faintly in the background when at idle, couldn't hear it while riding. A bit more pronounced when selecting "Power". He said it's nothing to worry about, they all do it just ride it and we'll watch it. Ok so slowly it's getting louder until I can hear it at slow speeds. When stopped at idle, it can be clearly heard and when either the "Power" or "Manual" button is selected it's very pronounced. So I dropped off the bike at the dealer for the 24000km service, new tyres and check out the noise. Well it's been two week now and they are still trying to find the cause. The dealer said he discussed it with the Suzuki Technical Guy at national level and nobody knows, they are saying open her up. I have to say I'm worried.
