Sorry I have been so long with the pictures. After looking at them, I realized that they need a lot of explanation to make sense. Actually, I just followed the instructions that came with the kit.
One area that needs particular attention is the moving of the starter control set on the left handle bar. It must be moved 3/4" inch inward to allow the thumb throttle to mount next to the rubber hand grip. The clamshell starter group has a tab that sits in a hole on the handlebar to keep it from rotating. I removed the starter group and drilled a new hole in the handlebar 3/4" inward. See the attached pictures.
Also, I wanted the cable to be tight against the handlebar all the way from the left to the right side. I was afraid I might be going through some brush or low hanging limbs and something catch the cable and pull on it. The result would be a sudden acceleration which could be bad. So I purchased a new, longer cable online that I could zip tie tight to the handlebars.
