Gilera runner 125 172 180 Electricity & Carburetor

So I have 2 questions in 1 thread.

1- Electricity
When using original ignition does anyone believe having the wiring hooked up with all the lighting and electric starter can affect your performance?

2- Carburetor 35mm+
Dellorto or Keihin?

 

Very little performance loss on electrics, what's spec on engine to need a 35mm carb?

 

Everythings upgraded and tuned only thing oem is exhaust and ignition

 

You are fine off on the original ignition and no, the electronics do not affect the performance
