    Do the SVHO have an O2 Sensor or Catalytic Converter?

    Just tried to search to see if the Yamaha SVHO has an O2 sensor from factory but just keep getting results for people installing them aftermarket?

    Do the engine have a Catalytic Converter or anything similar to control emissions?

    Thanks

    No they don't have a o2 sensor from factory....they have a ribbon it's like a catalytic converter on the manifold...

    Ok thanks for the responses just was curious because in my other post on the forum I was asking about blending fuels or using octane boosters to try to achieve a slightly higher octane rating because of the poor fuel quality where I live. The issue is that most race fuels/Avgas and some octane boosters contain led which is not good for Catalytic converts or O2 sensors.

    tune it for the fuel your going to be running, then remove the sensor and put the plug in. simple solution....
