bike misses when rolling on throttle

Hey guys, Ok, I fixed the leaking carb. It was a cracked overflow tube. I've got it so it will start and idle well, but when I head down the road it starts missing as I roll on the throttle. I have been through the carbs several times n search of another problem so I know they are clean. Float height is good. I am not sucking air around the intake boots. The CV slides move smoothly in the bore. I have new gas. Any ideas on what I may look at next? Thanks guys. Zeph
