Webbers or Bike Carbs

[Not Anumber]

I keep reading a lot of stuff on the forum about choice between webers or bike carbs which all has me confused. Do you know why people are lean to layout money for carbs when this often seems to require rejetting, sortink linkages and buying a dedicated manifold. How is it thought to be a better set up than just transplanting the fuel injection setup from the donor ? Before looking at the forum i'd just assumed this was the way to go partly because it's free and less bother but mostly because even in standard form it gives a combination between power and fuel economy, can be remapped when time allows and if it goes wrong it's all just standard injectors, air flow meter off the shelf. ?
