Throttle arrangement

To have a hardware adjusted idle and a good enough return spring something had to be made.
I took the return spring from a Buell throttlebody I had in the shop. But first I made a nylon bushing for the spring and shaft and then a bracket to hold the idle screw and stop screw for throttle travel.
Many templates of both cardboard and Pepsi can was made before I started with the real pieces. But soon enough I had some pieces I was satisfied with so I just welded them with the TIG. Drill holes, tap and some screws, some grinding and I had a throttle arrangement.
