I was told the servo buddy doesn't work well on the gen 4. what i would do is put the servo back on just to see if it goes away. have you gotten a reflash done yet?When I bought my Gen 4 back in Nov. I noticed that every once in awhile when I started the bike the red FI warning light would not go off. If I turned the bike off and restarted it the light would then go out. I was able to retrieve the error code and it's 39 which the service manual says is a ECU/CAN communication problem.
Once I restart the bike and the light goes off it never comes on again while riding. The problem has gotten worse this week and it happens almost every time I start the bike forcing me to shut it off and do the restart.
I finally took the bike to the dealer today and they checked all the wiring connections and nothing wrong was found. The dealer called the Kawasaki service support center in So Cal but they have never heard of the problem. The dealer will continue working with the service center next week but for now its a mystery and my 10 is stuck in the shop.
Has anyone out there heard of this problem? Any ideas??
Oh the bike was totally stock until a month ago when I added a Leo link-pipe and Servo Buddy. Adding these made no difference in the FI light issue. The bike runs perfect without any other problems even when the FI light is stuck on.
