ECU fueling or ignition problems...
I have an issue with an 09' zx10r with approximately 1190 miles on it. I took it for a ride yesterday and it will not rev or accelerate past 9500 RPM's in any gear. I can put it in neutral and it will rev past 9500 all the way to the rev limiter near 13000.
I took it on the road and did numerous pulls in 1st, 2nd, 3rd and it hits a brick wall at 9500 and will not go past it no matter how many times I tried it.
Bike has no Power Commander but has a 2 bros slip on.
So, to ensure it wasn't the fuel pump I swapped over my 05' zx10r fuel tank in place of the 09' fuel tank. It doesn't mount up the best but it works for some troubleshooting. I took it back out last nite and it did the exact same thing, it won't pull past 9500 in gear but will rev to the limiter in neutral.
I am concerned it maybe the ECU now, since I seen someone post up something close to the same problems as I have now but the member posted up what fixed it or if it got fixed.
It idles perfectly fine, starts up on the first hit of the starter and sounds great. So that rules out spark plugs and a few other things.
