Do you need non vacuum dizzy for bike carbs?

[rread97]

So I’m in the process of buying bike carbs and all the bits I need to fit, do I need a non vacuum dizzy to run these carbs? Can I run without or block the vacuum off? 
 

im already on a budget so just trying to save as much money as poss!

I have Yamaha R1 carbs on my 2.1 pinto. The distributor is a vacuum type and the set up works fine. As long as the engine is getting fuel delivered to it the dizzy will tell it when to fire. If the engine is running okay with the vacuum dizzy set up, it should be fine with the bike carbs. All you are doing is changing the fuel supply. You will need a pressure regulator in the fuel line as bike carbs only need a low pressure.
