Yes really. Instead of jetting/adjusting your carbs, you bought bigger ones. The problem was you IMO. Judging by your mods in your sig, you dont NEED 33's. You bike would run fine. But it also runs fine with 33's im sure. Again, you stock carbs where fine. Not all of us can afford to spend money on bigger carbs so we will rebuild stock ones and get them working because it's a cheaper alternative. And when we spank big carbs bikes, it feels even better.
People upgrade them for many reasons. Some are: they want more performance, to fallow the crowd, because someone said so, tired of taking the bowls off to change jets, found a good deal on bigger ones. I went with 30mm carbs to keep my low end power and i got a great deal on my carbs. So what you said about going with 30 or 33 may not be ideal for everyone set up.
IMO a person should talk to their builder and see which carb will perform best for their riding style, set up and port job.
muggzy, i run VF3 reeds on my bike. I love how crisp the throttle is. I personally hate the feel of stock reeds on a banshee.
