Jerky at 30-50 km/h

Hey Kwee
Maybe that’s the solution. But I think it’s quite strange that Kawasaki can’t fix it! As long as the warranty is valid I’m a little bit worried about flashing.

emission standards :/

I'm sure flashing would improve the engine behaviour but there are plenty of owners who don't have a flashed ECU and are not having the same problems. If my bike had this problem a couple of things I would check:

• Check to make sure throttles are balanced

• Reset accelerator/throttle position data in ECU

To be honest, on a new bike I would be surprised if either of these steps cured the problem that jpsylt and Galbert describe but they are zero cost/ zero risk tasks so maybe worth a try.

My H2SX is a bit "jerky" too at low revs. But I didn't considered it as a problem yet.

I can't compare my bike to yours Gilbert, but if it is "jerky" when your cruising within swedish cities at 50 km/h in 3rd gear, then we might have the same "problem". Cruising below 3000 rpm is not very comfortable on mybike, but on the other hand neither it wasn't comfortable on my old 2001 VFR800. Same problem there.... jerky below 3000 rpm. Maybe thats the reason, why I didn't consider that as a problem yet. Personally I can handle this behavior of my H2SX, I'm normally in first and second gear in town and well above 3000 rpm outside.

But as I said, I don't know if our bikes behave the same way or if your bike behave even worse. But for me I kind of expected a bike, thats capable of 11.000 rpm to "not like" low revs. But I'm curious whether Kawasaki has a solution for your bike.

Kör försiktigt och hej då från Tyskland!
