You need to roll them on more progressively, you cannot open flatslides like cv carbs, it's not necessarily a set up issue, sometimes you just need to "learn how to ride" with flatslides! Once you get it cracked you will love them!!!

Are you using a QAT? You need to use either the standard throttle or a simlar action as a QAT will pull the slides too quick and bog the motor.

A classic flatside problem is fuel bypassing the float valve seats via worn/perished O rings......................causes bogging down problems

Can you post a dyno fuel curve, & carb specs. These things are infinatly adjustable so you need to take note of,

Needle Code
Needle Clip position
Main Jet (Hex or Round) Size
Main Air Jet
Pilot Jet
Pilot Air Jet
Idle Screw Setting
Float level
Stack Length
Accelerator Pump Position

Engine Tune
Camshafts
Cam Timing
Exhaust System

CDI std or kit
Is the air solinoid still in use

There is really a lot to go through but they can be made to run really sweet.
Regards,
