Will a modified ignition affect carb tuning ???

Welcome all aboard, I have a 1992 Yamaha VXR 650 with the stock ignition and wires. I want to bump up to the MSD ignition enhancer and coil unit.
Currrently this ski has an aftermarket pipe and billet Aluminum carb adapter W/ K&N 59-2000 spark arrestor on it. The oil pump has been removed and I run 50 to 1 premix , Will this install affect my mixture ? Will I need to re-tune the carb? It is an SBN 44 Mikuni. Would I need to run hotter plugs?
Or stay with the NGK BR8S ???

Any help would be awesome.

You might have to run cooler plugs if you have more ignition. Shouldn't have to change anything else since it have nothing to do with letting more air or fuel into or out of your engine.
