O2 eliminator kit?

If memory serves most bikes only have 1 o2 sensor, a precat.

Its also pretty common that a lot of bikes have issues with the o2 sensors causing jerkiness on the throttle so if that does as it says it will help smoothness when going from no to some throttle. I know taking out the o2 sensor and disabling it on my bike deff helped the on-off throttle transition.
