05 z1000 cutting out

Hi all, I have an 05 z1000 and the engine suddenly cuts out whilst riding, its only does it on hot days and longer rides, if I ride locally in my town it's never happened. The first longer ride this summer and it cut out at 50mph after about 30 miles as if I'd hit the kill switch, no warning signs, no spluttering etc and no FI codes are stored. I replaced the fuel pump motor and filter last year and thought that had fixed the problem but obviously hasn't.. I've replaced plugs, coils, air filter, battery, fitted a PC3. Any ideas guys ? Its very frustrating and potentially dangerous. Any ideas ? Thank you for reading.

Hi,
We haven't figured out our similar problem yet but we are starting to think it may be engine heat related. The bike coughed after about 2 hours on a cool day.
What we're going to try is these things.
Going to replace the Tip Over Switch
Going to wrap the ECU and Power Commander with that metal heat reflecting sheet. Maybe keep the engine heat away from the electronics.
Maybe disconnect the PC from the system.
I'll try to keep everyone posted on anything we find out.

Yes I've dismantled the cap and checked it over and also the overflow/vent tube? that attaches to under left side of tank isn't blocked.

Thanks mad, I've just put my bike back together after checking, cam and crank sensors, sidestand switch, fuel cap vent, and fuel pump relay. So far the only thing I've found wrong was my fuel line was routed incorrectly, backwards instead of forwards which I've now corrected.

I agree its heat related but finding what is overheating causing the engine to cut out isn't easy. Mine has only ever cut out on hot days and longer rides 30 miles plus. It can cut out at any speed or even at a red light. I have just bought some heat reflective tape to put on bottom of tank near fuel pump to keep it a bit cooler.

I have an 03 that's only given me one problem in the three years I've had it and it was very similar to yours. I was about 110 miles from home doing around 80 or so when it suddenly turned off like I had hit the kill switch. I coasted over to the shoulder thinking it was something minor. I had it towed back home and gone over by a mc mechanic friend of mine and after 3 days of checking everything out he couldn't find anything definitive wrong with it. It wouldn't start when he was trying to find the problem so he gave up for the night and when he came back in the next day it started up like nothing was wrong. It's ran perfectly since then but now I'm scared to go too far from home for fear of being stranded again.

Hi, yes I'm the same, I won't go on long rides or use motorways due to the fear of it cutting out. Mine usually starts up after it stalled but I need to turn ignition off then on again but once its cut out I just want to get home asap.

I've found another possible solution on another Kawasaki forum. It involves turning over the reg/rec bracket like in the pic allowing a gap between the reg/rec and the plastic undertray, as its possibly overheating the ecu causing the bike to stall ?? Anyway this fixed the cutting out for the guy on the other forum. I take no credit for this idea.

I have this same issue. You'd think by now someone would've figured it out. I'm leaning toward a faulty fuel pump relay.
