My buddy has a 70-something Rupp Hustler mini bike he's trying to sell so he can get his license back. It runs great. The stock tecumseh 3.5 horse has been replaced with a briggs-n-stratton 3.5 horse. Starts easy, does a strong honest 35. Needs rear wheel(wobbly) and a seat pad (doesnt have one on it). Taking offers, pics up later today. Painted like a rat rod, flat black with whitewalls and red rims, looks sweet.
