O2 sensor eliminator — why?

[CIP57_imp]

I though about eliminating the O2 when i added the aftermarket exhaust but saw no positives only negatives. Running without it gives you a straight line A/F ratio (similar to a bike with carbs) , not able to compensate for elevation changes, cold, hot, low/high humidity. Piggyback controllers even have the ability to add there O2 as an add on.

But hey, if the bike runs better go for it
