New (to me) trx90 and new member

Traded out some electrical work for a 2006 Trx90. My daughter is 7 and has been riding a Kymco Mongoose 90 for 2.5 years (time to shift). On Wednesday I ordered a Teixeira Tech 3.5" over arms with Fox Floats front and back. Can’t wait to get her going. Anyway just changed the oil, cleaned out the carb, put in fresh gas and battery. Runs like a champ. Sat most it’s life and stock to the bone. When she’s ready (soon I’m sure) I’ll do the bolt on things.
I read to cut the pink wire? Is there a CDI i can change out or is cutting the pink wire the same result? So just air cleaner (soon) and a pipe way down the road. We live in central Ca. and desert, dune and trail ride equally.
