This is a short write up on how to install the Honda Minitrail hidden/internal throttle assembly. The hard part is the drilling and milling of the handle bars. Ideally, you will want to use a mill, but you could do this with a hand hand drill and grinders and files.
The process begins with drilling a 5/32" hole all the way through the bar 3.625" from the end of the bar. Follow this by a 27/64" drill through one side only. And finally mill a 5/16" wide slot from the hole you just drilled to about 7/8" from the end of the bar. Debur.
Route your cable and assemble.
