I'll keep this short. I live in Lahore and I want to buy a second hand 70cc (can be a China 70cc, no need of honda etc ) to basically tear apart, put back together and learn about engines as a whole hands on. (Engine can be smaller or bigger then 70cc, just needs to be cheap. Under 6k and complex enough to learn something if I open it) and it needs to be working. If its from a motorcycle maybe I'll tear apart the gearbox and learn something there too.
Any ideas ?
