Kawasaki's don't suck, but Scumrise does. My suggestion, don't hold your breath when you take to them. All mine had was a recall on an exhaust can ('03 6R problem), and it took them over 2 months before I got tire of not riding and went and took back my bike.

All I can say is good luck. It doesn't sound like a common problem, but it should be under warrenty, so you should have some luck with that. Hopefully, they will just swap the motor...never did truck their mechanics going inside a motor...
