Briggs and Stratton Powered Schwinn

[Thurman]

I built this bike over 25 years ago and it still runs strong. Tops out between 40 and 45mph. Very dependable. My grandson has it now and terrorizes his neighborhood regularly.

That's pretty bad as! I used to put premium leaded in my B&S powered TACO mini bike to gain a few MPH, but doubt it ever hit 45 mph. Blew a head gasket in the end.

Yeah, Tacos, Bonanzas and Rupps. I love those old mini bikes. We hop up the Briggs a little with studded head bolts, milled head, relieved deck, advanced timing and race fuel. Torque is added with long intake and tuned exhaust.
Starting a 5hp, we may gain a couple with mods.
