I am about done with the throttle. Lots of time. If I had to do it all over again I think I would make my own throttle like the earlier design but make it twist the normal way. Much easier to install. I did not get p/n770 and had to make it plus p/n 767 and 768 required fitting. And if I used the early style I wouldn't have had to alter the length of the handlebar and notch it either.
