are fuel reading on stock

[ebockus]

Lots of guys say these apex is run lean. I put a wide band air fuel ratio gauge on And set all my tuning to stock. It ran 12.8 bang on the money stock. Maybe it's just my machine but stock is perfect. just a fyi. I am planning to do the airbox mod and I'm adding fuel that's why I got the wide band And the hauck accelerator. I was just curious to see where would run before I modded everything.

My recollection is;

The 2011's & newer run lean.

The 2006 to 2010's are not lean.
