Re: refurbishment video
Cringe ! ! !
Apparently S.O.P. I have watched similar videos repairing the Indian made Royal Enfield motorcycles.....engine rebuild at the roadside, for example. Same techniques. Parts are cheap.
Most amazing is that after all the abuse, it starts easily and runs OK.
Shows how tough these engines are.
Indians may not have much to work with, but they are resourceful.
Appropriate technology.
