my zxr4 revs to 4000 rpm and cuts out

[07ref.jacksonr]

I was riding my bike hard when i miss a gear and the engine reved right out and the bike just cut out now when i start the engine the bike starts lovey and revs upto 4000 rpm no problem but soon as it gets t0 4000rpm it just cuts out. if you hold the choke in half way the bike will rev to 12000rpm and then just cuts out again its like it just cuts the spark i have tryed replacing the plugs still no luck if any one could help me i would be very greatful Thaks Roy

could the timing chain jumped a sprocket?

when it cuts out is it a clean cut or it is a stuttering one like fuel starvation?

if it was only slightly out it would start but it would most likely be lumpy from the offset.

clean cut does sound electrical....does it start again ok?

Yes its starts again strait away and ticks over perfect. even revs up to 4000 rpm and sound really smoot.
