I tried using this without a woodruff key and it slips every time I shut off the engine.
Using the woodruff key and kinetic box, it works. Its ok.
Using a parmakit box and NO woodruff key and it ripps. but it slips and then you have to drop the motor and re time it.

Kinda like putting a cdi on a french bike but you gotta get your light and find out where it fires first. Also kinda like hooking up an HPI with no line on the wheel. You gotta find the line. It's like riding a bike once you got it, you got it.

dang what a cool upgrade for vespa's! make sure you toss that old woodruff key and time this puppy, use your master skills to make your timing marks, tighten it down and after that it's pure fun!
