Love my 05 zx10. Got it because it was closest thing to a GP bike for street. !3,00 miles on it now and only problem is lower case cracking. had it fixed by kawisaki 1.5 urs ago, cost 4,500 buks. Now it looks like it has done it again. They said it has weak spot in case right above the water pump. it cracks right where a bolt hole is and oozes oil. Small amount but any is too much. Kawasaki corp accused me of rough riding and refused to pay at 1st. I ride curves and wheelies, no drag strip or stetched BS. I love this bike and treat it like my kids but I cant see keeping it if i keep having this issue. Taking it to get it looked at sat-6-13-09. maybe they will fix again. if not they can have it and am done with kawasaki. Only bike I have ever owned and think they have engineering issues with the lower motor casing. Any repies would be appreciated.
