Street Demon 625 experience so far

I dont get post like this. Everybody is entitled to their opinion. But your post really isn't helping me much either. I wont write a carb of as garbage just because one person is telling me it is. If you read my first post I have a lot of positive things to say about this carb. I just have a bog when I stomp on it to WOT. Many carbs untuned for the setup could have that. I would be suprised if it's impossible to cure taking the time tuning it.
Ignore it.
Are you sure its a lean bog?
What elevation are you at? Most factory setup are for 72*F sea level. If your at high elevation you are rich and need a tune kit. I always tune the secondary door spring in 2nd gear WOT pulls. I'm a TQ guy but the Demon is similar. I run a Demon 750DP and they are good carbs IMO.
