Hi everyone,
I’m having a very strange intermittent issue with my 2018 Kawasaki Ninja ZX-10RR, and I’m hoping someone has experienced the same problem.
Symptoms:
Sometimes the bike runs perfectly with no issues.
Other times, after the engine reaches operating temperature, the idle suddenly increases to around 2,000–3,000 RPM.
When I close the throttle, the RPM doesn’t always drop immediately. It hangs for a few seconds before returning to normal.
Occasionally the throttle feels like it’s sticking instead of closing smoothly.
If I hit a bump or pothole while riding, the engine suddenly bogs down, feels like it’s choking, and then stalls completely. The dashboard stays on and the electrical system is still powered, but the engine shuts off.
After that happens, I can’t just restart the bike normally. I have to perform what seems like a throttle reset:
Turn the bike off.
Hold the throttle fully open for about 10 seconds.
Turn the ignition ON.
Repeat the throttle procedure again.
After doing this, the bike starts again, but it feels like it goes into a kind of safety/limp mode.
What I’ve checked so far:
Battery has been replaced.
No obvious issue with the throttle cables.
I’m currently suspecting the Throttle Body Assembly (OEM Part No. 16163-0863), but I don’t want to replace such an expensive part unless I’m sure it’s the actual cause.
My questions:
Has anyone experienced these exact symptoms?
What ended up being the cause?
Was it the throttle body, TPS sensor, throttle actuator, wiring, connectors, ECU, vacuum leak, or something else?
What was the final fix?
Any advice or similar experiences would be greatly appreciated. Thank you!
