Handlebars
Here I've cut the right side handlebars to weld in the inner part of the internal throttle. It's a Pat Kennedy unit
Here's the assembly together. Finishing this is one of the last things done on the bike. I have to the carb in place to do that.
One of the slots cut for the internal wiring.
I've pulled the wiring harness and installed the switch cover. Note the extra wire hanging loose.
This is why. The extra wire gives you a service loop so you can work on the switches if you have to.
