i just got my first bike... i gotta do some work to it , but before i bought it i was told that it was dropped so the carbs were out of sink... i have never heard of that... how do i resinchronize 4 carbs... do i need to have someone mess with the linkeage? it runs fine but when you get on it at about 2500-3300... it hesitates for a sec , i was thinking it was just boggong down but dont know anything about a sport bike so i dont know how they are supposed to act... when it gets above that and hits the power band its gone.............. literally.. any thoughts.... oh and the owner said the carbs were just rebuilt...
