I have a complete Bike Bug on a period correct Hiawatha Flying Jet 3 speed bike. I have the original Manual with it too. Engine runs great. Comes with a few spares. Price is $250 but I will entertain offers.
I have a complete Bike Bug Motor Kit too. This is complete with all the required parts to mount to a bike. I have cleaned the tank and carb and feel this unit will run just fine once assembled on a bike. Not all the parts are pictured. The carb is not pictured but looks like new inside and out. $100 and willing to entertain offers.
