From what I am reading the code is for being to rich.
the bike has new injectors, o2 sensor, spark plugs, air filter, throttle pedal, fuel pump, and I swapped the maf from another 900. What am I missing here I have pulled on wires and connectors without luck. The only way I can get the code to clear is to unplug the maf and plugging it back in but after 15 min of riding it comes back. I’ve tried running the bike without the air filter to create a lean condition without luck.

I just had the same Ranger with the same code and it was caused by a dirty t-map sensor. They had incorrectly seated the air filter and it sucked A LOT of dust into the engine. Cleaned it up with some MAF sensor cleaner and the code went away. Although, the engine is toast.

The bike also has a lot of what I would call blow by or crankcase pressure. Is this normal?

Time for a cylinder leak down test.
