My zzr400 keeps blowing the cdi - ZZR 400 kawasaki Motorcycles

You could try closely looking at each crankshaft for any part numbers moulded into it. These should help identify which engine the crank fits. A good Kawasaki specialist should be able to help figure out the difference with these numbers.

I had the same problem with my 2006 Vector. Blown 4 CDI units. Changed out complete wiring harness and Stator, new plugs, Carbs. We narrowed it down to the coils. They were for an RX1 (based on the part number). swapped out with OEM vector coils. installed new CDI.. Sled is running flawless now.

sounds like alternater to me, check voltage from is ok. http://www.electrosport.com/media/pdf/fault-finding-diagram.pdf

Were you using the winch when it failed?
Apparently winch wiring issues tend to take out the CDI......
heres just one case...

spary wd-40 on all electrical connection that was expossed to water liberally.....if that doesnt do it, then you probably got water in your pulse generator system coils and will have to pull the cover off and see if theres water in there.

HELLO; Sounds like a bad rectifier.

My kawasaki has the same noise, specially when cold, but this should go off when your bike temp goes 1/4.thats my observation with my ZZR400

Hi!
Not being well familiar with the ZZr's however what is the Red LIne on this particular model? if it is around 10.000 then your rev limiter is kicking in stopping you blowing the engine.
Hope this helps!
