The only reason clones exist is because of: (1) demand, (2) someone else can manufacture it cheaper, and (3) penny wise pound foolish consumers, but that's just my opinion.
I had a carburettor gasket fail within 20 000km twice on a German OEM part at one stage. I put it down to the rubber used reacting to the petroleum distillates in the petrol, yet it was meant to carry petroleum. I used a pirate for 236 000km without ever failing.
Years later I found out a different German manufacturer voids motor warranties on their bikes if you use a certain brand of fuel here in SA (sorted since) the South African fuel producer / refiner had an additive destroying all rubber seals on the engine.
Sometimes, the OEM doesn't get it right not even German ones
