Kawasaki zx6r ninja 2002 carb
So I recently purchased a zx6r ninja 2002 carb. It started stuttering round 7500 revs in gear. I pulled the engine and on cyl 3 the inlet valves werent seating properly. I then the grinded it with some grinding paste and it then seated properly. I also striped the carbs and cleaned everything with carb cleaner. I also installed a new tps. After putting back the engine it started and didnt miss anymore. But now it doesnt rev up at all even if I twist the throtle to the max. Please help and I hope it is relevant. Thank you

 

wow, from a carb rack swap to valve lapping. That is some serious work.

did you verify the cam positions after you assembled the engine?

I am just fishing here of course.

 

Yess I had the timming set by an engineer in this field. Could this problem be the ecu

 

I have not seen a pre 2005 ecu fail yet. So I am unable to answer that one. (The 2005 models ecu failed due to the exhaust heat under the seat as an example. The 2002 model is different of course.)
Do you think that you may have overcooked the ecu? Charging issues in the past? Did you verify that the coils are not the culprits?
