It generally looks good, but the clearances are loose. It's going to need to have washers added as shims to keep it from rocking from side to side at the fulcrum and over-stressing the hinge points. And the hinge points are just cap screws in drilled holes. Really what you'd expect given the cost so no real complaint there. But it's going to be a little tempting to try to add bushings or bearings when I install it.
Some sort of instruction diagram would have been helpful. Taking it apart and reassembling it with the components in the different positions is interesting, but it's difficult to see how all the different alternatives would actually work.
The universal throttle cable that they recommend to go with it looks a little sketchy, primarily because what looks like the pedal end consists of a loop in the cable that will fit over a bolt at the top the lever, likely riding on and pulling against the sharp thread edges, and the carb end is just collar with a set screw. A little searching has turned up some other, more secure-looking possibilities. Particularly one of the Lokar XTC universal cables.
