Choose your own damn carby... Lol nah... There's just so much choice you are gonna get so many different answers lol... But basically:

I'd just take a guess you will most likely need a carby between 24mm and 30mm. I just guessed some sizes but principal is still the same.

Small Carby (24mm round or 26 Oval)=Best off the line, Best torque, good midrange, Lacks top end.
Medium Carby (28mm Oval or 26mm Round)=Good All round, Good Torque, Strong midrange, Good Top
Large Carby (30mm Oval or 28mm Round)=Poor off the line (Flatspots/Bog), Good Midrange, Awesome top and really revs out high.

Thats just for the sizes... Then there is flatslide, D-Slide and round slide but i don't know much about that. From what i have read the flatslide is the best followed by the D-slide then to round slide. After that there's quite a few brands like Mikuni, Keihin, OKO, Molkt, etc...
