carb out of sync symptoms?

i have about 1000 miles on my 02 yzf600r now, i changed the oil and filter at around 800 miles. anyways, lately its a huge pain to get the bike to start and alot of time when i rev the bike hard from idle, it kinda chokes before it spins up. i know that i need a carb sync now that i'm out of teh breakin period, but are these symptoms common? and will a carb sync definitely fix these problems?

well i got my bike back from the dealer, they told me that they changed out the spark plugs because the ones i had were fouled. which is weird to me because there's only 1k miles on the bike so far, what would have ruined my plugs. i always try to turn off the choke as soon as i can keep the bike running w/out it. they said that no ochanges were made to the carb, it was fine. they said that the idle was set to low, which is why it was lagging when i revved it, and its not as quick to spin up as, say, the r6. i just don't know why the bike wasn't starting very well, and if it wasn't starting very well because of the bad plugs, then what was it that caused the plugs to be fouled. could alow idle foul the plugs? i have the plugs because i asked the mechanic to give them to me. another yami dlr told me that the bike not starting right up shouldn't have been due to the low idle because having the choke on raises the idle right up anyways. i dunno...
