It's a test fit part, jlccnc will make the final piece out of 6061

No idea what they are trying to achieve outside of the "trying to kill this engine" part. I'm just hoping for the video of what goes wrong. (Hopefully not one of someone getting injured)

I'd run it for the prototype, just for funsies, until a shop can make the real part or the plastic breaks. It might last longer than you think.

It's a honda dax replica by skyteam, with a yx125 motor, barely cracks 50mph but it's the one that get used all the time,

Charger is a very rare 60's VW smog pump, by my meaurements it's a 94cc per revolution
