Hey man, haven't seen you on here for awhile! Glad you're back for a minute. Lol. If I'm not mistaken, CT pipes are made by the same company which makes the F7, so the pipes are one in the same. Pretty sure. If this is true, the only advantage of getting the F7 over the CT is multiple color choices for the silencer.
A 35mm carb will be fine for the BBK, especially if you're not running a stroker crank. Bolt it up, jet it, break it in well, and have at it!
