Cbr 954 start on third or fourth try it will start I’ve replace fuel pump starter kill switch fuel pressure regulator new battery and just did valves but still won’t fire up on first try but once started bike runs beautiful no issues anyone else had same issue and was able to resolve

 

Could use a bit more info on what its specifically doing whether its cranking or not and if you have injector pulse spark and fuel pressure

 

Yes cranks strong and after third or fourth try bike will fire up and run perfect
