I had a problem with the little plastic kill switch for the Raw 2 stroke motor kits, i have had a few kits for different bikes and they all broke or didnt always work. So I decided to pick up a micro switch from radio shack and soldered the wires on and put it in place of the old one. Its an easy fix id recommend anyone to do if they by one of these kits.
heres a link to the switch i used
