First, I just wanta say that I love this bike (when it is running right) but now it is not...I have around 200 miles on my month old klx450r...I think...not sure because the front sending unit stopped working during the second ride and is on back order. The bike has been in the shop now for over a week...it starts fine, runs for a few minutes then starts to spit and sputter and cuts off as soon as you give it gas. The CDI box has been changed out, the coil has been changed out, now the mechanic is swapping sensors from a new klx450r on the floor. The kawasaki tech people have no idea...they have suggested numerous things and all have been done and still there is nothing to show for it. I am going crazy now. Is anyone else having these problems? Let me know if you have figured anything out. Thank God for my 36 month warranty, but all I want to do is ride!
