NC23 idle/rev issues

when my bike starts (when it can be bothered), i apply full choke and no throttle.. the choke keeps it ticking over, still its kind of warmed up when i can drop the choke a bit. but when i go to rev it, it de-revs instead of revs. From my knowledge that is caused from too much fuel as if i pull the throttle back slowly, the revs increase..
is this caused by wrong fuel / air mixture or something else?
once the choke is completely off, the bike dies. unfortunatley i cant ride it as i have no chain or sprockets as they will be purchased within the next couple of weeks.
could any shine some light on the situation to why it dies when revved (what steps i need to do to fix the problem)
thanks guys

Is it running on all 4 cylinders? when its started, lick your finger (wont burn so much!) and touch the downpipes, see if they are all hot

sorry to mess you about wozza, just went to try a sparkplug to make sure its sparking, to notice that the spark plug cap wasnt even in the engine. it was laying on top of the engine from where id removed it from the spark plug and forgot to plug it back in again!!

everything seems to be working in order!
the revving is instant now. i guess my bike is female, and she's just came off her monthly
roll on the 29th for my Mod2 then the 30th April for the RAF meet
i need to thank a few guys on here for the help
