So I messed my 93 CBR up by doing a Carb Sync. They seem to be fine and fully synced REALLY close (using a homemade manometer).

Now it starts and idles, but as soon as I go to give it gas it just bogs down and dies.

ANy help?

Loaded on a trailer tonight to take to a shop tomorrow. I just dont want to be ripped off

 

Sorry to hear that.
was the bike running badly before the carb sync?
did one carb need significantly more adjustment than the rest?
have the carbs been cleaned recently?

let us know what happens.

 

Did you:

1- Check that your tool was calibrated by hooking all of the meters up to a single cylinder or a vaccum pump and check that your tool was actually accurate?

2- Did you properly re-plug all the holes for checking vaccum on all of the cylinder intakes?


Outside of those two, I can't envision what doing a job like that would result in. Perhaps you didn't hook a vaccum line back up properly? It sounds like there's an air leak, and while it idles fine, when you go to rev the motor it just is sucking in way more air than fuel, not getting the proper ignition, and is then dieing.

 

what Jesse said, but also - how much turning of screws/adjusting did you actually do.

Unless your carbs were waaaaaay off to begin with, we should be talking about very small adjustments that wouldn't cause the end result you have.
