Did the car just start doing this? If so you probably have some trash in the metering block. I had picked up something and had to clean the carb. I think if its been doing this since bolted on its a lean condition. I had an extreme lean condition and it would bog like you said. My carb is a BG 650 DP. I jetted up and fixed the lean condition. Wide band on the dyno is the only way to tune. Good luck
