Default 99 gsxr carb problems HELP!!!!

i have a 99 gsxr 600. i have had bad luck with getting this thing running right. i took it to a mechanic, and he just made it worse...definatly will not be going back to him, but anyways, i found a good friend who works on these bikes. had him clean and resynchronize the carbs. the bike has yoshi pipe and headers, and k&n filter. so we rejetted it to what the recommended jets are for these custom items. now i am having a problem with the bike running extremely rich, (shooting flames out the exhaust). also when i start it, the rpms stay at around 4-5k for atleast 30 seconds, and then when i mess around with the idle adjustment, it goes down. everytime i rev the bike up, the rpms stick at around 4-5k until i let out clutch. but then when coming to a stop, it will die. we replaced the needles in the carbs, and made sure it was jetted right. what could be causing this problem? any help would be great, thanks!!!

It may not be a carburetor problem, But rather electrical. Did you take a look at the pick up coil? It may be retarded and your trying to compensate with the fuel air ratio by mistake.
