How do you remove the rev limiter on your 50cc 2 stroke scooter?

Get the wiring diagram for your bike. I downloaded a great tank gy6 service manual that matched both my 50cc 4-stroke tank and baja scooters. I found CDI modules had a yellow and green wire going to something called speed selectable unit... I assumed a rev limiter. I diconneted the wires to it first. The bike didnt run.Then I tried connecting the green and yellow wires together, bypassing the rev limiter, and it worked great, so i did it to both bikes.
