Point is having the crank rebuilt cost less than either the speedo or the alternator.. and unlike the alternator, once fixed stays fixed.
Truth is Enfields have no quality control. so sometimes they make bad parts which get fitted at the factory. Sometimes good parts are fitted badly at the factory. Sometimes badly made parts are badly fitted at the factory. All these things make themselves known to the unfortunate owner. Once fixed it is a good bike. I have heard rumours that just to confuse customers, sometimes they properly assemble a whole bike with all good parts.
The big end failed because the crankpin was badly made (poor case hardening) and like the rotor above flaked metal which the rollers in the big end bearing did not like. It was aided and abetted by them machining the woodruff key slot on the crankshaft badly resulting in too advanced ignition timing. I made an off set woodruff key to fix this. Now it runs relatively smoothly and will even accelerate whilst going slightly uphill in top gear. It is a lovely bike for touring and on it I make more miles per day than I did on my BMW.
