cbr600f starting problem

I have a 1994 cbr600f. When i cold start it i put full choke on start and leave for a few mins while i get my helmet & jacket etc and it runs fine. When i go back to the bike and turn the choke off it splutters and dies and then doesnt want to start and eventually i get it going and then its fine. I've tried leaving it warming up longer and it still does the same thing. Is it something im doing wrong or is there something wrong with the bike?

I've tried to include as much detail as possible

Any help greatly appreciated!!

once its started, back off the choke a bit then let it run. after your going ease the choke off completlely. chokes not a boost switch

Pretty much as above.

I'm yet to find a situation where i actually NEED any more than half choke to get the bike to fire/idle though.

I'll flip the choke half on, fire it up, put my lid & gloves on, hop on it, ride off & flip the choke off as i'm going down the main road.

You're leaving the choke "on" for too long.

All this warming your bike before riding it is overrated, all you need to do is ensure that the engine oil has reached all the correct places, you are then good to go.

You only need the choke to start the bike, once your moving, just turn the choke off!

Your bike engine will not be fully "warmed" up until you've actually ridden it for a few miles.

...Just start it.

If it tries to cut out, keep adding a little choke till it will idle.

Switch it off as soon as it will idle without it.

still, if your using choke now and its not really cold you might want to have a look at your fuelling, carbs ect. or get your local bike garage to look.

Honda's don't like the choke being on for very long. The 'blade kicks up a fuss if it gets the merest hint of choke after about 10 seconds, Kwak on the other hand will not run smooth until up to temperature.

Ok so iv tried what everyone suggested 3 times now it doesnt like no choke so iv been using a little choke and then leave it a few seconds and turn the choke off and it doesnt really like it but carrys on running but it doesnt run right it feels bogged down and unresponsive and by the end of my road it cuts out and then doesnt want to start again. But once u get it going it runs fine. I dont no what im doing wrong and dont no if its me or the bike.

Im really getting fed up with it now lol anyone got any more ideas?
