Which Carb Is Better?

28mm is stock. I bought the CPW today. It should be in this week. It came with it's own jet kit, and Motion Pro throttle cable. I didn't want to buy a wehole intake boot, and all of that other stuff for a bigger carb. This was a good bolt on for some more performance. I paid 125 plus 14 shipping. I thought that is was a good deal, especially since it was brand new!
