Correct, and I do different things for different applications. I will get more into this and maybe even start a new thread just for this. This harness being theres no fan or lights will be pretty simple, however as you stated, grounds are #1 priority. I will be replacing some wiring, repinning and also checking terminal tension on both cdi connectors. I also ensure atleast 1-2 motor mounts ground the motor to the frame, if it had a fan I would run a ground from t-stat housing to the frame since I make jumper harnesses for the temp sensor to allow constant fan. It all depends on what I or someone else, and where the want the cdi, reg/rec mounted.
