I've got a 1.0l polo fox, I'm gunna buy a polo gt and do an engine swap but i dont know whether to put bike carbs on the engine or just leave it to injection?

it depends on what you want from it, it would be cheaper and easier to use the injection but won't sound as good although i'm not sure what kinda performance figures you'll get from the bike carbs over the injection?

abd with injection mate :)

Just use a 1.4 ABD with bike carbs from a 600-750 4cyl sports bike. I used that set-up and it was the best all-rounder I've ever ran. Sweetest sound,very economical,nicely rapid yet tractable,reliable,smooth and flexible.. No need to look further really,unless you want mental speed.

Seems pointless breaking a GT for less,though I've never ran a GT.

Thats my word on my experience,before the haters jump in.
