Hi all ive recently bought my first zxr 400 for use on the track, it has developed a fault which after hours of checking i cant solve. some days the bike will start and sound brill then the next day will not run at all. ive checked most of the basics like spark plugs and carbs but still she wont run. can someone point me in the right direction. help

bad connection somewhere on the wiring? dirt in the carbs? dodgy fuel? dodgy coils? dodgy fuel pump or relay? my fuel pump used to pack up every now and again and id give it a bang and it would go again, choke working ok? dodgy ignition switch?

sorry for not gettin back to you cheers for your reply, sorted starting probs now.
bikes runnin brill, done a couple of track days on it now and i love it, cornering is fantastic just love goin round and overtaking the boys on there big bikes.
