1966 Briggs Powered Schwinn Stingray

#44
Tested it today. I'm using a Hillyard clutch on it, and I like how it operates. Seems to "slip" pretty good when I get on it and accellerate smoothly. This is 22" tire diameter, 225 pounds of overweight grandpa on it, all with a 3HP BS. There is a lot of vibration, but no worse than most vintage minibikes. I've got a PZ20 slide carb on it. Jets aren't marked, and I was set to get some different sizes, but it's working fine. Starts first pull every time with choke. I hate the way that banana seat feels like Curt Hartney in 9th grade giving me a wedgy, but it blue AND sparkly. You won't see me hiding my mug on this place, so I apologize for that. It's been a rough week. Test Ride 3.jpg Test Ride 4.jpg Test Ride1.jpg Test Ride2.jpg

Thanks for the nice comments. I do appreciate hearing how awesome I am, because most of the time, I am a dumb ass. For example, remember yesterday when I typed: "Seems to "slip" pretty good when I get on it and accellerate smoothly."

It was slipping because I was pushing oil out of the drain return on the PTO housing, having pushed the seal too far in. In my defense, I had to dig up the bearing type sump cover, find the bearing, figure out which seal I needed, because in the "book" there are these photos and options and applications, but no specs. Anyway, it's a bastardized bearing engine.

Clutch 10t, JS in 17t, JS out 9t, sprocket 46. (iirc) It feels like I could go a bit lower. I got on it and let it accellerate and it went about 70 MPH on the Predator scale, or 27 MPH on the flathead scale. I did not want to go any faster. Note I have a more robust front wheel coming in with 12 ga. spokes, and a meatier tire (Moped) at 16X 2.25 which of course fits a 20" heavy duty BMX 20 inch.
