If this is the case then it was the assembler at the factory. The headset is original to the bike. I'm pretty sure the bike is out of warranty now, darn it. I suppose it would not hurt too much to ask the dealer who originally sold the bike if they would replace the headset under warranty. They could use a good laugh I suppose.

No "indexed" or gritty steering, play seems to be the same no matter which way the bars are turned.
