ZX9/E mis-fire problems FIXED

The diagnosis and theory in my previous email was 98% correct it was fuel starvation in the manner I thought; however it wasn't fuel draining back to the tank that was the problem, it was a lack of 12Vdc at the pump. Pillock!!!!. Yes these engines run without the pump running!!! The engine suction isn't powerful enough which is why Kwak fit a nice little electric pump. I had connected the the blue and black fuel pump supply to an incorrect feed. Simple.

Thanks for the reply from Jasper, his problem sounds like sticking pilot jets.
£20 spent at the local bike centre will get them cleaned and should cure the problem.
