So if you asked me, I would throw it in the scrap iron container.
The Blata with the little wheels drives really crappy and you have almost no parts.
Isn't to ride anyway. Just a project foor fun.
Ok, you have to know it.
Engine parts are normaly not the problem. Is there a name on the cylinder, look at the cylinderbase.
Pretty sure he said it was a frame. Had no engine.
Rides crappy or not. Just clean it up, put a Chinese 40mm or 44mm on it whether its a shelf queen, you resell it, or a rider.
Its fun no matter what. Find all the used parts you can.
Its all about hot rodding and having fun. I honestly would spend $300 rebuilding it my way then buying another bike from someone else and inherit a $300 bikes problems. and dump $200 more in it. Plus the journey is what its about AND you built it with your own two hands.
