Scat-Bat Mini-Bike --- My first entry into Mini Bikes

#2
I've been wanting a mini bike since I was a kid in the 70's. Spent many hours staring at the Sears catalog dreaming of one. Bought this the other day, says Bird Engineering on the sticker, model 703004. What would this have had on it for an engine.

Does anyone know what size engine it would have had? I assume 3 1/2 hp but could be wrong. Could you go 5 HP on it? Tiller engine or any vertical work?

You’ll need a horizontal engine….and yes if it fits run it….hs40 or hs50 either one….but I’d guess factory was a h30….
